Technical Field

[0001] This utility model relates to a generating and measuring device, specifically a linear acceleration generating and measuring device. Background Technology

[0002] Currently, near-shore submersibles exhibit a variety of motion states during operation, with static hovering, surfacing, submerging, linear motion, and linear acceleration being the most common. Among these, the sudden transition from a static to linear acceleration is the most critical technical aspect. Existing acceleration measurements all measure rotational acceleration; therefore, the ability of all components on the near-shore submersible to withstand this level of acceleration is a crucial technical indicator. Utility Model Content

[0003] To address the aforementioned technical problems, this invention provides a linear acceleration generation and measurement device. This device simulates the linear acceleration of a near-shore submersible and measures whether all components on the submersible can withstand this intensity of acceleration. It simulates the submersible's operation from standstill to acceleration and then from high speed back to standstill, thereby detecting the stability of the submersible's components. Simultaneously, it measures the linear acceleration value under simulated conditions and displays the curves and performs data analysis.

[0004] The technical solution adopted by this utility model is as follows: a linear acceleration generating and measuring device, which includes a rodless pneumatic cylinder, a linear acceleration sensor, a pneumatic end cap, a hydraulic damper, an air pipe connector, a pneumatic intermediate bracket, corner pieces, an air inlet pipe, an air outlet pipe, a manual reversing valve, a traction block, a circuit board housing assembly, a pneumatic tray base plate, an air source pipe, and a pneumatic tray base plate cover plate.

[0005] The air supply pipe is connected to one side of the manual directional valve, and the other side of the manual directional valve is connected to the air inlet pipe and the air outlet pipe respectively. The other ends of the air inlet pipe and the air outlet pipe are connected to both sides of the rodless pneumatic cylinder through air pipe connectors respectively. The pneumatic end caps are installed at both ends of the rodless pneumatic cylinder. There are two hydraulic dampers, which are installed on the pneumatic end caps at both ends of the rodless pneumatic cylinder respectively. The corner pieces are connected to the pneumatic end caps by bolts. The pneumatic intermediate bracket is pressed onto the rodless pneumatic cylinder through a slot. The pneumatic intermediate component plays the role of supporting the rodless pneumatic cylinder. One side of the pneumatic intermediate bracket is pressed onto the rodless pneumatic cylinder through a slot, and the other side is fixed to the worktable. The pneumatic tray base plate is connected to the magnetic coupling slider on the rodless pneumatic cylinder by bolts. The linear acceleration sensor and the traction block are installed on the pneumatic tray base plate by bolts. The circuit board housing assembly is pressed between the pneumatic tray base plate and the upper cover plate of the moving tray base plate by bolts, and the circuit board housing assembly is fixed to the upper cover plate of the pneumatic tray base plate by bolts.

[0006] Furthermore, the manual directional valve is a 5-position 3-way valve.

[0007] Furthermore, the magnetically coupled slider has four bolt holes.

[0008] Furthermore, the pneumatic tray base plate is provided with mounting threaded holes.

[0009] Furthermore, the pneumatic pallet base plate and the upper cover plate of the moving pallet base plate are connected by four bolts.

[0010] Furthermore, the rodless pneumatic cylinder has threaded holes at both ends for installing air pipe connectors.

[0011] Furthermore, the air inlet pipe, air outlet pipe, and air pipe connector are pneumatically quick-connected.

[0012] Furthermore, the connection method between the air inlet pipe, air outlet pipe, air source pipe and manual reversing valve is a pneumatic quick-connect plug-in connection.

[0013] Furthermore, the device can achieve linear acceleration measurement by driving the device under test through a linear cylinder, and the acceleration of the linear cylinder is achieved by the thrust of the air source.

[0014] The beneficial effects of this invention are as follows: It provides a linear acceleration generation and measurement device. It can realize the acceleration of a linearly moving object, generating acceleration during the process from rest to high speed, measuring and displaying the acceleration value. This device simulates the working state of a near-shore submersible from rest to acceleration and then from high speed back to rest, thereby detecting the stability of the submersible's components. Simultaneously, it measures the linear acceleration value under simulated conditions and displays the curve and performs data analysis. Conventional mechanical sliding acceleration can only reach about 1.2g, while the acceleration of this device can instantaneously reach about 7g, and the average acceleration over 1 second can reach greater than 2g. These parameters are unattainable by mechanical sliding acceleration, and the data indicators and effects are far superior to those of mechanical sliding acceleration. Attached Figure Description

[0018] The air supply pipe is connected to one side of the manual reversing valve, and the other side of the manual reversing valve is connected to the air inlet pipe and the air outlet pipe respectively. The other ends of the air inlet pipe and the air outlet pipe are connected to both sides of the rodless pneumatic cylinder through air pipe connectors respectively. The pneumatic end caps are installed at both ends of the rodless pneumatic cylinder. There are two hydraulic dampers, which are installed on the pneumatic end caps at both ends of the rodless pneumatic cylinder respectively. The corner pieces are connected to the pneumatic end caps by bolts. The pneumatic intermediate bracket is pressed onto the rodless pneumatic cylinder through a slot. The pneumatic intermediate component plays the role of supporting the rodless pneumatic cylinder. One side of the pneumatic intermediate bracket is pressed onto the rodless pneumatic cylinder through a slot, and the other side is fixed to the worktable. The pneumatic tray base plate is connected to the magnetic coupling slider 101 on the rodless pneumatic cylinder by bolts. The linear acceleration sensor and the traction block are installed on the pneumatic tray base plate by bolts. The circuit board housing assembly is pressed between the pneumatic tray base plate and the upper cover plate of the moving tray base plate by bolts, and the circuit board housing assembly is fixed to the upper cover plate of the pneumatic tray base plate by bolts.

Simultaneously, the air inlet and outlet of the manual directional valve are connected to the inlet and outlet pipes, which in turn connect to the rodless pneumatic cylinder. The manual directional valve has three operating modes. When the manual directional valve switches from the middle position to the left position, compressed air is injected into the inlet pipe of the rodless pneumatic cylinder.

Similarly, when the manual directional valve switches from the middle position to the right position, compressed air is injected into the outlet pipe of the rodless pneumatic cylinder.
