[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-52997 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional display example 1, only the current measurement value is displayed on the screen, so it is not possible to grasp the time series transition of the measurement value, and in order to grasp the time series transition of the measurement value, it is necessary to operate to switch to a separate screen of display example 2. Furthermore, in display example 2, the time series transition graph of the test force and the transition graph of the displacement are displayed overlapping on a common time axis, so it is difficult to distinguish whether the two transition graphs show the test force or the displacement.

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a high-speed tensile testing machine will be described as a testing device according to the present invention.

[0012] [1. Configuration of high-speed tensile testing machine] FIG. 1 is a diagram schematically showing the configuration of a high-speed tensile testing machine 1 according to this embodiment. The high-speed tensile testing machine 1 performs high-speed tensile testing by applying a tensile force (test load) at a predetermined impact speed to a test piece TP of the material being tested. The high-speed tensile testing machine 1 comprises a testing machine main body 2, a control device 5, and a computing device 6. The test objects are various materials, industrial products, and parts or components of industrial products, and the test piece TP is prepared in accordance with predetermined standards for material testing. The test piece TP is, for example, a resin material of a predetermined composition.

[0013] The testing machine main body 2 includes a table 10, a pair of support columns 11a, 11b erected on the table 10, a cross yoke 12 suspended between the pair of support columns 11a, 11b, and a hydraulic cylinder 30 fixed to the cross yoke 12. The hydraulic cylinder 30 constitutes a loading mechanism in the testing machine main body 2 that applies a tensile force to the test piece TP, and is operated by hydraulic oil supplied via a servo valve 33 from a hydraulic source (not shown) arranged inside the table 10.

[0014] An upper chuck 20a is connected to the piston rod 31 of the hydraulic cylinder 30 via a run-up jig 25 and a joint 26. A lower chuck 20b is provided on the table 10 via a load cell 27, which is a force detector. The upper chuck 20a and the lower chuck 20b correspond to a pair of gripping tools in the present disclosure. With this configuration, the testing machine main body 2 pulls up the piston rod 31 at a predetermined impact speed. As a result, a force acts on the upper chuck 20a and the lower chuck 20b, rapidly separating them, and this force acts as a tensile force on the test piece TP gripped by the upper chuck 20a and the lower chuck 20b. In this way, the configuration that applies a tensile force to the test piece TP corresponds to a test load applying unit in the present disclosure.

[0015] The testing machine main body 2 is provided with a stroke sensor 32 that outputs a stroke detection signal Da to the control device 5 in accordance with the amount of movement of the piston rod 31, which corresponds to the amount of displacement of the upper chuck 20a, and a load cell 27, which is a force detector that outputs a force detection signal Db indicating the tensile force to the control device 5.

[0016] An extensometer 40, which is a displacement detector, is attached to the test piece TP. The extensometer 40 has upper and lower arms that grip the test piece TP and displace together with the test piece TP, and detects the amount of extension (displacement) of the test piece TP by detecting the displacement of the upper and lower arms using a linear sensor or the like. The extensometer 40 outputs a displacement detection signal Dc indicating the amount of displacement of the test piece TP to the control device 5.

[0017] The control device 5 controls the operation of the testing machine main body 2 to execute the high-speed tensile test, and during the execution of the high-speed tensile test, acquires the stroke detection signal Da output from the stroke sensor 32, the force detection signal Db output from the load cell 27, and the displacement detection signal Dc output from the extensometer 40 for each predetermined measurement cycle. A computing device 6 constituted by a personal computer or the like is connected to the control device 5 by wire or wirelessly.

[0018] The stroke detection signal Da, force detection signal Db, and displacement detection signal Dc acquired by the control device 5 are transmitted as time-series measurement data M(t) (t indicates the time point of measurement) from the control device 5 to the calculation device 6 at appropriate timing. The calculation device 6 displays a test monitor screen on the display 61, which shows the execution status of the high-speed tensile test, based on the measurement data M(t). The calculation device 6 also functions as an input interface for setting various setting parameters (e.g., impact velocity) related to the high-speed tensile test in the control device 5.

[0019] 2 is a diagram showing the functional configuration of the control device 5 and the arithmetic device 6. The control device 5 includes a communication unit 50, a servo drive unit 51, a test execution unit 52, and a detection signal acquisition unit 53. The control device 5 is a computer unit including a processor such as a CPU or MPU, a memory such as a ROM or RAM, a storage device such as an HDD or SSD, and an interface circuit for connecting sensors, peripheral devices, etc. The processor of the control device 5 executes a control program for the control device 5 stored in the memory or storage device, thereby realizing the functions shown in FIG. 2.

[0020] The servo driver 51 outputs a control signal to the servo valve 33 to operate the hydraulic cylinder 30 so that the piston rod 31 is pulled up at a predetermined speed. The test execution unit 52 executes a high-speed tensile test by controlling the operation of the hydraulic cylinder 30 via the servo driver 51. The configuration in which the test execution unit 52 controls the operation of the hydraulic cylinder 30 corresponds to the control unit in this disclosure.

[0021] The detection signal acquisition unit 53 includes A / D conversion circuits 54a, 54b, and 54c that sequentially acquire the stroke detection signal Da, the force detection signal Db, and the displacement detection signal Dc, perform A / D conversion, and output the signals. The outputs of the A / D conversion circuits 54a, 54b, and 54c become the measurement data M(t) that is transmitted from the control device 5 to the calculation device 6.

[0022] The A / D conversion circuits 54a to 54c operate in synchronization with a common clock signal, and at a predetermined measurement sampling period, they synchronously capture the stroke detection signal Da, the force detection signal Db, and the displacement detection signal Dc and output time-series measurement data M(t) consisting of digitally converted values ​​of these signals. The clock signal may be generated by an appropriate clock circuit, such as a clock circuit provided in a processor.

[0023] The arithmetic device 6 is a computer unit having a communication unit 60, a display 61 (corresponding to the display unit in this disclosure), a processor 70, a memory 80, etc. A program 81 for controlling the arithmetic device 6 is stored in the memory 80. The processor 70 functions as a load measurement unit 71, a change measurement unit 72, and a display control unit 73 by reading and executing the program 81.

[0024] The load measurement unit 71 measures the test force applied to the test piece TP based on the digitally converted value of the force detection signal Db included in the measurement data M(t). The change measurement unit 72 measures the displacement of the test piece TP (corresponding to the change in the test piece of the present disclosure) based on the digitally converted value of the displacement detection signal Dc included in the measurement data M(t). The change measurement unit 72 may also measure the displacement of the test piece TP based on the digitally converted value of the stroke detection signal Da included in the measurement data M(t). Alternatively, the displacement of the test piece TP may be measured using a non-contact extensometer that detects the displacement of the test piece TP from an image of the test piece TP captured by a high-speed video camera.

[0025] The processing executed by the load measurement unit 71 corresponds to the load measurement step in the display control method of the present disclosure, the processing executed by the change measurement unit 72 corresponds to the change measurement step in the display control method of the present disclosure, and the processing executed by the display control unit 73 corresponds to the display control step in the display control method of the present disclosure.

[0026] [2. Test monitor screen display control processing] 3, the procedure for the display control process of the test monitor screen to be displayed on the display 61, which is executed by the computing device 6 when a high-speed tensile test is being performed by the control device 5, will be described. Note that the display control process of the test monitor screen to be described below is also executed when the control device 5 is controlling the operation of the hydraulic cylinder 30 to keep the position and load of the hydraulic cylinder 30 constant during "preparation" or "standby" periods that are not during a general test, or when the control device 5 is not controlling the operation of the hydraulic cylinder 30 (for example, when the hydraulic source of the hydraulic cylinder 30 is stopped).

[0027] 3, when the display control unit 73 receives test start data indicating that a high-speed tensile test has started from the control device 5, the process proceeds to step S2, and starts displaying a test monitor screen 100 on the display 61, as shown in FIG. 4. Referring to FIG. 4, the test monitor screen 100 includes a load monitor image 100a displayed in the upper half area (corresponding to the first area in the present disclosure) of the test monitor screen 100, and a change monitor image 100b displayed in the lower half area (corresponding to the second area in the present disclosure) of the test monitor screen 100.

[0028] The display control unit 73 displays, as the load monitor image 100a, a load measurement symbol image 101 that clearly indicates that the display object is the measurement status of the test force, a load measurement value image 102 that indicates the current measurement value of the test force (corresponding to the predetermined measurement point in the present disclosure), a load measurement graph image 103 that indicates the transition of the test force from the start of the test, and a load level indicator image 104 that indicates the measurement level of the test force. In the load monitor image 100a, the load measurement value image 102, the load measurement graph image 103, and the load measurement symbol image 101 are displayed in the upper half area (first area) of the test monitor screen 100 in a positional relationship that allows their respective correspondence to be recognized.

[0029] The load measurement graph image 103 shows the transition of the test force from the start of the test, with the vertical axis representing the test force level and the horizontal axis representing time t, and shows a reference point (zero point) 103a of the test force, a positive limit 103b of the test force, and a negative limit 103c of the test force. The range of the time axis t corresponds to the predetermined measurement period of the present disclosure. The range of the time axis t is auto-scaled according to the time width from the start to the end of the test.

[0030] The test starts when the user performs a start operation, and ends when the user performs a stop operation, or when a preset test time has elapsed, or when the test force or the displacement of the test piece TP has reached a limit, etc. The load level indicator image 104 indicates the reference point (zero point) of the test force with 104a, and the level of the current measured value of the test force relative to the reference point 104a is indicated by the length of bar 104b.

[0031] Furthermore, the display control unit 73 displays, as the change monitor image 100b, a change measurement mark image 105 which clearly indicates that the display object is the displacement of the test piece TP, a change measurement value image 106 which indicates the current measurement value of the displacement of the test piece TP (corresponding to the predetermined measurement point in the present disclosure), a change measurement graph image 107 which indicates the progress of the displacement of the test piece TP since the start of the test, and a change level indicator image 108 which indicates the measurement level of the displacement of the test piece TP. In the change monitor image 100b, the change measurement value image 106, the change measurement graph image 107, and the change measurement mark image 105 are displayed in the lower half area (second area) of the test monitor screen 100 in a positional relationship which allows their respective correspondence to be recognized.

[0032] The change measurement graph image 107 shows the progression of displacement from the start of the test, with the vertical axis set to the displacement level of the test piece TP and the horizontal axis set to the same time t as the load measurement graph image 103, and shows a displacement reference (zero point) 107a, a positive displacement limit 107b, and a negative displacement limit 107c. The range of the time axis t corresponds to the predetermined measurement period of the present disclosure. The change level indicator image 108 shows the displacement reference point (zero point) as 108a, and the level of the current measured displacement relative to the reference point as indicated by the length of bar 108b.

[0033] The load measurement graph image 103 and the change measurement graph image 107 are arranged vertically on the test monitor screen 100, which allows the user of the high-speed tensile testing machine 1 (the person conducting the test) to easily understand the test force applied to the test piece TP and the changes in the displacement of the test piece TP by comparing them on the same time axis t.

[0034] In addition, for the load measurement graph image 103 and the change measurement graph image 107, no numerical values ​​or symbols are displayed on the vertical and horizontal axes of the graphs, making it possible to easily see only the changes in the test force and the displacement of the test piece TP. The load measurement value image 102 may be displayed superimposed on the load measurement graph image 103. Similarly, the change measurement value image 106 may be displayed superimposed on the change measurement graph image 107.

[0035] In the following step S3, the display control unit 73 determines whether or not measurement data M(t) has been received from the control device 5, and proceeds to step S10 if measurement data M(t) has been received, or proceeds to step S4 if measurement data M(t) has not been received. In step S10, the load measurement unit 71 measures the test force applied to the test piece TP based on the digital conversion value of the force detection signal Db included in the measurement data M(t). In the following step S11, the change measurement unit 72 measures the displacement of the test piece TP based on the digital conversion value of the displacement detection signal Dc included in the measurement data M(t).

[0036] In the next step S12, the display control unit 73 updates the load measurement value image 102, load measurement graph image 103, load level indicator image 104, change measurement value image 106, change measurement graph image 107, and change level indicator image 108 displayed on the test monitor screen 100 based on the current test force measured by the load measurement unit 71 and the current displacement of the test piece TP measured by the change measurement unit 72, and proceeds to step S4.

[0037] In step S4, the display control unit 73 determines whether or not test end data indicating the end of the high-speed tensile test has been received from the control device 5. If the display control unit 73 has not received the test end data, the display control unit 73 proceeds to step S3 and executes the processes from step S3 onwards again. On the other hand, if the display control unit 73 has received the test end data, the display control unit 73 proceeds to step S5 and ends the display control process.

[0038] [3. Other display examples of the test monitor screen] 4 illustrates a test monitor screen 100 in which the measurement period is from the start to the end of a high-speed tensile test. In another embodiment, when a test is performed in which a test force of a predetermined load pattern is repeatedly applied to a test piece, a test monitor screen 110 may be displayed on the display 61, which is updated every time one cycle of the load pattern elapses, as shown in FIG.

[0039] 5, the display control unit 73 displays, as a load monitor image 110a, a load measurement symbol image 111, a load measurement value image 112, a load measurement graph image 113, and a load level indicator image 114. The load measurement value image 112 displays the positive peak value (200.0) and the negative peak value (-150.0) during the measurement period of the test force displayed in the load measurement graph image 113.

[0040] The load measurement graph image 113 shows a reference point (zero point) 113a of the test force, a positive limit 113b (alarm setting value), and a negative limit 113c (alarm setting value). The range of the time axis t corresponds to the predetermined measurement period of the present disclosure. The average value and amplitude value of the load may also be displayed on the load measurement graph image 113. The load level indicator image 114 shows the reference point (zero point) of the test force as 114a, the positive peak level of the test force as indicated by the length of bar 114b, and the negative peak level of the test force as indicated by the length of bar 114c.

[0041] Furthermore, the display control unit 73 displays, as the change monitor image 110b, a change measurement mark image 115, a change measurement value image 116, a change measurement graph image 117, and a change level indicator image 118. The change measurement value image 116 displays the positive peak value (6.0) and negative peak value (-2.0) of the displacement during the measurement period of the displacement of the test piece displayed in the change measurement graph image 117.

[0042] The change measurement graph image 117 shows a reference point (zero point) 117a of the displacement of the test piece, a positive limit 117b (alarm setting value), and a negative limit 117c (alarm setting value). The range of the time axis t corresponds to the predetermined measurement period of the present disclosure. The average value and amplitude value of the displacement may also be displayed in the change measurement graph image 117. The change level indicator image 118 shows the reference point (zero point) of the displacement of the test piece with 118a, the positive peak level of the displacement with the length of bar 118b, and the negative peak level of the displacement with the length of bar 118c.

[0043] 5 shows a case where a sine wave-shaped test force is repeatedly applied to the test piece, but as shown in Fig. 6, a test monitor screen 120 that displays not only a simple sine wave or triangular wave but also one cycle of an actual wave may be displayed on the display 61. The test monitor screen 120 shown in Fig. 6 includes a load monitor image 120a displayed in the upper half area of ​​the test monitor screen 120 and a change monitor image 120b displayed in the lower half area of ​​the test monitor screen 120, similar to the test monitor screen 110 shown in Fig. 5.

[0044] The display control unit 73 displays a load measurement mark image 121, a load measurement value image 122, a load measurement graph image 123, and a load level indicator image 124 as the load monitor image 120a, similar to the load monitor image 110a shown in Fig. 5. Furthermore, the display control unit 73 displays a change measurement mark image 125, a change measurement value image 126, a change measurement graph image 127, and a change level indicator image 128 as the change monitor image 120b, similar to the change monitor image 110b shown in Fig. 5.

[0045] 4. Other Embodiments 4, the display control unit 73 displays the load measurement graph image 103 and the change measurement graph image 107 in an array in the vertical direction of the test monitor screen 100, with the time axis in common. In another embodiment, the load measurement graph image 103 and the change measurement graph image 107 may be displayed in an array in another direction, such as the horizontal direction of the test monitor screen 100.

[0046] 4, the display control unit 73 displayed the load measurement value image 102 and the load measurement graph image 103 arranged in the horizontal direction of the test monitor screen 100, but the load measurement value image 102 and the load measurement graph image 103 may also be arranged in other directions, such as the vertical direction of the test monitor screen 100. The same applies to the change measurement value image 106 and the change measurement graph image 107.

[0047] 4, the display control unit 73 displayed the load level indicator image 104 between the load measurement value image 102 and the load measurement graph image 103. In another embodiment, the display of the load level indicator image 104 may be omitted.

[0048] 4, the display control unit 73 displayed the change level indicator image 108 between the change measurement value image 106 and the change measurement graph image 107. In another embodiment, the display of the change level indicator image 108 may be omitted.

[0049] In the above embodiment, as shown in Fig. 4, the load measurement graph image 103 and the change measurement graph image 107 are made easy to view by not displaying numerical values ​​or symbols on the vertical and horizontal axes of the graphs. In another embodiment, numerical values ​​and symbols may be displayed on the vertical and horizontal axes of the graphs, or the user may be able to switch between displaying and hiding the numerical values ​​and symbols through a selection operation.

[0050] In the above embodiment, the high-speed tensile testing machine 1 is shown as the testing device for performing the predetermined test of the present disclosure, but the testing device of the present disclosure may be any testing device that performs a predetermined test by applying some kind of load to a test piece and measuring the change in the test piece in response to the applied load. The load applied to the test piece may be a load (tension, bending, compression, shear, etc.), as well as heating, cooling, etc.
