Technical Field

[0001] [Cross-Reference to Related Applications] This application claims the benefit of priority from U.S. Provisional Patent Application No. 63 / 778,139, filed March 26, 2025, entitled "Dynamic Testing System Control Valve Adapter", the content of which is incorporated herein by reference in its entirety.

[0002] Embodiments of the present disclosure relate generally to test stations for dynamic testing systems, and more specifically to speed control of working fluid pressure actuators of test stations.

Background Art

[0003] Dynamic testing systems, such as the dynamic testing system developed by MTS Systems Corporation, are equipped with test stations that perform various tests by applying loads and displacements to test objects using working fluid pressure actuators. The test stations may include, for example, a vehicle test station that applies simulated driving conditions to a moving vehicle, or a building test station that applies simulated seismic activity to a building.

[0004] The actuators of the test station are driven by working fluid flow. The operations performed by each actuator are carried out using control valves (e.g., proportional control valves) that regulate the flow rate and direction of the working fluid flow through the actuators. Control signals and power from the test station are supplied to each of the control valves via a series of cables spanning distances that may exceed 150 feet.

Summary of the Invention

[0005] Upgrading existing legacy control valves in a test station may be desirable. However, such upgrades may not be supported by the existing legacy cables used in the test station. As a result, upgrading such control valves may require additional, costly replacement of legacy cables.

[0006] Embodiments of the present disclosure relate to an adapter for connecting to a control valve of a test station configured to control the fluid flow through a working fluid pressure actuator, an assembly comprising the adapter, and a test station comprising the adapter. The adapter facilitates the connection between a legacy cable and the control valve.

[0007] One example of the adapter comprises a control input, a control output, a power input, and a first power output. The control input is configured to receive a valve control signal, and the control output is coupled to the control input and configured to connect to the valve control input of the control valve. The power input is configured to receive power from a power source, and the first power output is coupled to the power input and configured to connect to the valve power input of the control valve. Embodiments of the adapter also include a fuse connected in series between the power input and the first power output, a position input configured to connect to the valve position output of the control valve, a position output coupled to the position input, and / or an enable / disable input and an enable / disable output.

[0008] An example of an assembly includes an adapter and a control valve. The adapter includes a control input section, a control output section, a power input section, and a first power output section. The control input section is configured to receive valve control signals, and the control output section is coupled to the control input section. The power input section is configured to receive power from a power source, and the first power output section is coupled to the power input section. Embodiments of the adapter also include a fuse connected in series between the power input section and the first power output section, a configured position input section and a position output section coupled to the position input section, and / or an enable / disable input section and an enable / disable output section. The control valve includes a valve control input section connected to the control output section and a valve power input section connected to the first power output section.

[0009] One example of a test station in a dynamic test system comprises a working fluid pressure actuator configured to drive the operation of the object under test using a working fluid flow, a test station controller configured to transmit control signals via a control cable based on a test program, a power supply configured to supply power, an adapter, and a control valve. The adapter comprises a control input unit coupled to the control cable and configured to receive control signals from the test station controller, a control output unit coupled to the control input unit, a power input unit configured to receive power from the power supply, and a first power output unit coupled to the power input unit. Embodiments of the adapter also include a fuse, a position input unit and a position output unit, and / or an enable / disable input unit and an enable / disable output unit connected in series between the power input unit and the first power output unit. The control valve comprises a valve housing, a valve body housed within the housing and having a position that controls the flow rate and direction of the working fluid flow, a valve control input unit coupled to the control output unit, a valve power input unit coupled to the first power output unit, and a valve controller configured to control the position of the valve body based on control signals received at the valve control input unit.

[0015] [Figure 6] This is a simplified diagram of an example of a controller according to an embodiment of the present disclosure. [Modes for carrying out the invention]

[0016] Embodiments of this disclosure are described more fully hereafter with reference to the accompanying drawings. Elements identified by the same or similar reference numerals refer to the same or similar elements. However, various embodiments of this disclosure can be embodied in many different forms and should not be considered as being limited to the embodiments described herein. Rather, these embodiments are provided so as to make this disclosure thorough and complete and will fully convey the scope of this disclosure to those skilled in the art.

[0017] The functions described in this document may be performed by a single controller, multiple controllers, or at least one controller. Where used in this document, when one or more functions are described as being performed by a “controller,” for example, a specific controller, one or more controllers, or at least one controller, the embodiments include the execution of one or more functions by a single controller or processor, or by multiple controllers or processors, unless otherwise specified. Furthermore, where used in this document, when multiple functions are performed by at least one controller, all functions may be performed by a single controller, or some functions may be performed by one controller and others by another. Therefore, the execution of one or more functions by at least one controller does not require that all functions be performed by each of the controllers.

[0018] Figure 1 is a simplified diagram of an example of a dynamic test system 100 according to an embodiment of the present disclosure. The test system 100 may comprise one or more test stations 102, each of which may be configured to perform a test or situational simulation by applying force and / or displacement to an object under test 103 (e.g., an automobile, a building, etc.) using a working fluid (hydraulic) actuator 104 driven by a working fluid flow 106.

[0019] Flow 106 may be provided based on a working fluid flow 108 generated by one or more hydraulic power units (HPUs) 110. The system 100 may include an accumulator 116 that stores pressurized working fluid received from the HPU 110 and discharges a working fluid flow 118 that can be used to form the flow 106 supplied to the test station 102. The system 100 may include a distributor 120 that receives the working fluid flow from the HPU 110 and / or the accumulator 116 and distributes the working fluid flow 106 to the test station 102. Other configurations of the system 100 may be used to supply the required working fluid flow 106 to the test station 102.

[0020] The system 100 may be a closed system in which the low-pressure working fluid flow 106' discharged from the test station 102 returns, for example, as a mixed return flow 124 or the like that returns to the HPU 110 through the working fluid pressure distribution system 120.

[0021] The system controller 126 may operate to control various aspects of the system 100, including the functions of the HPU 110, valve mechanisms (e.g., valve mechanisms of the accumulator and / or the distributor), and / or other aspects of the system 100 for supplying the required working fluid flow 106 to the test station 102.

[0022] Figure 2 is a schematic diagram of an example of a test station 102 according to an embodiment of the present disclosure. As described above, the test station 102 includes a plurality of hydraulic actuators 104, such as hydraulic actuators 104A to 104D, configured to apply a force to a test object 103 and / or drive an operation. Each of the hydraulic actuators 104A to 104D is driven by a corresponding flow portion 106A to 106D of the working fluid flow 106 generated by one or more of the hydraulic power units 110 (Figure 1).

[0023] Each test station 102 may comprise a test station controller 130 that is generally configured to perform a test on a test object 103 based on, for example, execution of a test program stored in a non-transitory computer-readable medium. The test station controller 130 controls the actuator 104 to apply force and / or motion to the test object 103 in a conventional manner in response to execution of the test program, via control of working fluid flows 106A to 106D using the corresponding control valves 132.

[0024] The computing device 134 may be configured to generate a graphical user interface that allows a user to interact with and / or control the test station 102, execute test programs, view data, and / or perform other tasks, for example via a series of communications with the test station controller 130.

[0025] One or more safety inlet valves 136, such as solenoid valves, can control the inflow of high-pressure working fluid flow 106 to the test station 102, for example in response to a control signal (e.g., an emergency stop) from the test station controller 130, the system controller 126, or another suitable device. Each safety inlet valve 136 has a fully open state that provides a path that barely restricts the movement of the working fluid flow 106 to the test station 102. The valve 136 also has a closed state or a substantially closed state, in which the valve 136 blocks or substantially blocks the working fluid flow 106 to the test station 102. The solenoid of the valve 136 may have a default state or a de-energized state corresponding to the closed state or the substantially closed state.

[0026] Figure 3 is a simplified diagram of an example of a test station 102 according to an embodiment of the present disclosure. As described above, the test station 102 comprises a test station controller 130, and at least one working fluid pressure actuator 104 and its corresponding control valve 132. In Figure 3, only a single pair of working fluid pressure actuators 104 and control valves 132 are shown for the sake of simplicity, but it will be understood that the test station 102 may comprise two or more actuators 104 and corresponding control valves 132, as shown in Figure 2.

[0027] A control valve 132 for each working fluid pressure actuator 104 controls the flow rate (e.g., gallons / min) of the working fluid flow 106 to the actuator 104, which is received from a high-pressure source 137 (e.g., one or more of the HPUs 110 or the accumulator 116), and operates to discharge the flow 106' to a low-pressure reservoir 138 (e.g., back to the reservoir of the HPU 110). Furthermore, the control valve 132 controls the direction of the flow through the working fluid pressure actuator 104 to control the operation applied to the test object 130.

[0028] In one example, a working fluid pressure actuator 104 comprises a cylinder 140 and an actuator rod 142 having a piston 144 housed within the cylinder 140. The cylinder 140 has a first port 146 and a second port 148 through which a working fluid flow 106 passes. A valve 132 controls the direction of movement of the actuator rod 142 by controlling the direction of the working fluid flow 106 through the first port 146 and the second port 148, and controls the speed at which the actuator rod 142 moves relative to the cylinder 140 by controlling the flow rate of the working fluid flow 106.

[0029] The control valve 132 can take any suitable form. Examples of the control valve 132 include a servo valve or solenoid valve configured to provide the variable flow rate and direction control described above. As shown in Figure 3, the control valve 103 generally comprises electronic equipment 150, a valve body 152, and a valve body drive unit 154. The valve body 152 has an adjustable position that controls the direction and flow rate of the working fluid flow 106. For example, the valve body 152 can take the form of a spool, and the valve body drive unit 154 can take the form of a servo. An example of this type of control valve 132 is described in U.S. Patent Application Publication No. 2016 / 0123355. The electronic equipment 150 is configured to control the valve body drive unit 154 to adjust the position of the valve body 152 in response to an actuator command signal 156.

[0030] During the execution of the test program, the test station controller 130 emits a reference signal 164 regarding the desired operation to be performed on the test object 103 by the working fluid pressure actuator 104. Each actuator 104 is equipped with an actuation sensor 166 configured to sense parameters of the operation performed by the actuator 104, such as displacement and / or force, and to emit a feedback signal 168 indicating the sensed parameters. The actuation sensor 166 may include, for example, a displacement sensor 166A, such as a linear variable differential transformer, configured to detect the displacement and / or movement of the actuator rod 142 relative to the cylinder 140 and generate a feedback signal 168A indicating the detected displacement and / or movement, as shown in Figure 3, and / or a load cell 166B, configured to detect the force applied by the actuator 104 to the test object 103 and generate a feedback signal 168B indicating the detected force. A conventional conditioner circuit 169 can be used to process signals 168A and / or 168B (e.g., amplification, filtering) to generate the final feedback signal 168.

[0031] The actuator controller 170 is configured to compare a reference signal 164 and a feedback signal 168 corresponding to each actuator 104 and to emit a differential signal 172 to the corresponding control valve 132. The electronics of the control valve 132, such as the valve controller 174, adjust the flow rate and / or direction of the fluid flow 106 to produce the desired operation based on the differential signal 172. In Figure 3, the actuator controller 170 is shown to receive a single reference signal 164 and emit a single differential signal 156 corresponding to the described actuator 104, but the actuator controller 170 can be configured to receive multiple reference signals 164 from the test station controller 130 for each working fluid pressure actuator 104 of the test station 102 and to emit differential signals 172 to control the corresponding valve 132.

[0032] Test station 102 has been in use for many years and can utilize legacy control valves 132, which are controlled via differential signal 172 and power transmission via a corresponding legacy control cable 176, as shown in Figure 3. For example, if the control valve is a 252 series servo valve manufactured by MTS Systems Corporation, the legacy cable 176 can take the form of a shielded multi-core transmission cable supplying the analog current-driven control signal and power (e.g., ±250mA) required by the legacy control valve.

[0033] Newer control valves, such as the 255 series servo valves manufactured by MTS Systems Corporation, the servo proportional valves manufactured by Domin (e.g., SxPRO), and other modern control valves, are generally incompatible with legacy cables 176 used with many existing test stations 102. For example, legacy cables 176 may not be able to fully connect to the newer control valves (e.g., due to fewer pins), may not be able to supply the necessary signals or power, and / or may be unsuitable for other reasons. As a result, when upgrading test station 102 with newer control valves, legacy cables 176 generally have to be replaced with updated cables. This can be a complex and costly process due to the length and location of legacy cables 176 within test station 102, which generally hinders the upgrade of control valves.

[0034] Embodiments of the present disclosure relate to an adapter that enables an upgrade to a legacy control valve 132 without the need to upgrade the corresponding legacy cable 176. As shown in the simplified diagram of Figure 4, the adapter 180 is generally configured to connect the legacy cable 176 to the control valve 182, and the control valve 182 can take the form of an upgraded, modern control valve having functions and input / output functions unique to the legacy control valve 132. Thus, the control valve 182 can replace one or more of the control valves 132 in the test station 102 shown in Figure 2 and operate to control the flow 106 to one or more of the actuators 104.

[0035] The control valve 182 may include functional components similar to those of the legacy control valve 132, such as a valve body 152 and a valve body drive unit 154, operating in a similar manner to the corresponding components of the legacy control valve 132. The control valve 182 may also include electronic equipment 184 that can be configured to perform functions similar to those of the electronic equipment 150 of the legacy control valve 132. However, the electronic equipment 184 may have different input and / or output units and may be configured to perform functions not performed by the electronic equipment 150 of the legacy control valve 132.

[0036] Figure 5 is a simplified diagram of an example assembly comprising an example of an adapter 180 connected to a control valve 182 according to an embodiment of the present disclosure. The illustrated input and output sections can each take any suitable form that can be housed in appropriate connectors.

[0037] In some embodiments, the adapter 180 includes a control input unit 186 and a control output unit 188 that receive a control signal 172 from a legacy cable 176, and the control signal 172 is supplied to the control valve 182 via the control output unit 188, for example, at the control input unit 190. The electronic equipment 184 of the control valve 182, for example, the valve controller 192, is configured to control the valve body 152 based on the control signal 172, as described above.

[0038] In some embodiments, the control valve 182 has different power requirements than the legacy control valve 132. The adapter 180 may include a power input 193 that can be coupled to a suitable power supply 194 and configured to supply the required power. The power supply 195 received at the power input 193 is supplied to a power output 196 that can be connected to a power input 197 of the valve electronics 184. In one example, the power supply 194 provides a power supply 195 of 24VDC and a current of up to 2.0 amps, which can power other components of the test station 102, such as other adapters 180, etc.

[0039] In one embodiment, the adapter 180 includes a fuse 198 positioned in series between the power input section 188 and the power output section 194. The fuse 198 is configured to trip in response to transient power surges in order to protect the valve electronic equipment 184.

[0040] The adapter 180 may include one or more additional power inputs 188 and / or power outputs 194. For example, the adapter 180 may include a second power output 196' connected to the power input 193 or to another power input (not shown), as shown in Figure 5. A fuse 198' can be used to provide transient power surge protection to any component receiving power through the power output 196'.

[0041] In some embodiments, as shown in Figure 4, the control valve 182 includes a position sensor 200 configured to detect, for example, the position of the valve body 152 relative to the housing 202 of the valve 182 and to output a sensor signal 204 indicating the detected position. An electronic device 184, such as a valve controller 192, is configured to generate a position signal 206 based on the sensor signal 204 indicating the detected position of the valve body 152. The position signal 206 is transmitted via the position output unit 208 of the valve 182 and can be received by the adapter 180 at the position input unit 210. The position signal 206 can be supplied to the position output unit 212 of the adapter 180, which can be coupled to a test station controller 130 (Figure 2) or another controller of the test station 102.

[0042] In one embodiment, the position signal 206 transmitted via the position output unit 208 is an analog signal having a voltage representing the position of the valve body 152, and the adapter 180 includes an analog-to-digital (A / D) converter 214 that converts the analog position signal into a digital signal, which is then supplied to the position output unit 212. The A / D converter 214 can be powered using power received at one of the power input units 188 of the adapter 180.

[0043] In some embodiments, as shown in Figure 5, the control valve 182 includes an E / D input 216 that receives an enable / disable (E / D) signal 218 from, for example, the test station controller 130 or another controller of the test station 102. The E / D signal 218 is supplied from the input 216 to the E / D input 220 of the control valve 182 via the E / D output 222 of the adapter 180. When the E / D signal 218 has a first state (e.g., logical low voltage), the electronics 184 or valve controller 192 prevents the valve body drive 154 from moving the valve body 152 relative to the housing 202, and when the E / D signal 218 has a second state (e.g., logical high voltage), the electronics 184 or valve controller 192 allows the valve body drive 154 to adjust the position of the valve body 152 based on a control signal 172.

[0044] As shown in Figure 4, the adapter 180 can also be configured to connect to a data communication channel 222 (e.g., Ethernet for Control Automation Technology (EtherCAT®), controller area network (CAN), etc.) that the test station 102 uses to communicate data 223. As shown in Figure 5, the adapter 180 may include a communication port 224 that connects to the data communication channel 222 and a communication port 226 that can connect to a component of the test station 102, such as a communication port 228 of a valve electronics device 184.

[0045] The adapter 180 may comprise a housing 230 that supports and / or encloses its components. Each of the inputs (e.g., control input 186, power input 193, etc.), outputs (e.g., position output 212), and communication ports (e.g., communication ports 224 and 226) may have a corresponding connector, or one or more of the inputs, outputs, and ports of the adapter 180 may be combined into a single connector. The housing 230 may also comprise one or more cables having connectors that support one or more of the inputs, outputs, and / or ports of the adapter 180.

[0046] For example, the housing 230 may include a connector 232 with a control input 186 for facilitating connection to the legacy cable 176, as shown in Figure 5. The adapter housing 230 may also include a connector 234 with a control output 188 and a power output 196, and configured to connect to the control input 190 and power input 197 of the valve electronic equipment 184. The housing 230 may include a cable with a connector 232 for simplifying connection to the cable 176, and / or a cable with a connector 234 for simplifying its connection to the control valve 182.

[0047] The controllers of system 100, such as the system controller 126, test station controller 130, actuator controller 170, valve controllers 174 and 192, can take any suitable form to provide the various functions described herein, such as the controller 240 shown in Figure 6. The controller 240 may comprise one or more processors 242 and memory 244. The one or more processors 242 are configured to perform the various functions described herein in response to the execution of instructions stored in memory 244, such as test programs.

[0048] One or more processors 242 may be components of one or more computer-based systems and may include one or more control circuits, a microprocessor-based engine control system, and / or one or more programmable hardware components such as a field-programmable gate array (FPGA). Memory 244 represents local and / or remote memory or computer-readable media. Such memory 244 comprises any suitable, patentable computer-readable media and does not contain transient waves or signals. Examples of memory 244 include conventional data storage devices such as hard disks, CD-ROMs, optical storage devices, magnetic storage devices, and / or other suitable data storage devices. Controller 240 may include circuitry 246 used by one or more processors 242 to receive input signals 248, issue control signals 250, and / or communicate data 252 in response to one or more processors 242 executing instructions stored in memory 244.

[0049] While embodiments of this disclosure are described with reference to preferred embodiments, those skilled in the art will recognize that modifications may be made in form and detail without departing from the spirit and scope of this disclosure.
