Problems solved by technology
[0004] The present invention aims to solve the problem that the vibration force frequency monitoring equipment of the vibration cylinder used in the hydraulic dynamic test bench cannot make the pressure plate that transmits the vibration force move smoothly, so that the position of the extruded workpiece is inaccurate, and it is easy to cause vibration during the vibration process. Causes the vibration force to be unbalanced, resulting in uneven monitoring data

The invention relates to a vibration applying oil cylinder vibration force frequency monitoring device for a hydraulic dynamic test bed. The device comprises a workbench, supporting columns are weldedto the periphery of the bottom end of the workbench, first threaded rods are in threaded connection with the interiors of the lower ends of the supporting columns, base plates are welded to the bottom ends of the first threaded rods, and a display is placed on one side of the top end of the workbench. In the present invention, when a vibration applying oil cylinder body pushes a pressing plate toextrude a workpiece to be detected for vibration monitoring, compression springs in grooves in the two sides of the pressing plate can extrude a C-shaped plate to move towards supporting rods, rollers inside are tightly attached to the supporting rods, the rollers rotate through first bearings to assist the lifting movement of the pressing plate, so that the pressing plate is more stable in the lifting process, the pressing plate is prevented from shaking to cause loosening and falling of the workpiece in the vibration operation process of the pressing plate on the workpiece to be detected, the vibration can be applied more uniformly, and the detection accuracy is improved.
Description
technical field [0001] The invention relates to vibration force frequency monitoring equipment of a vibration cylinder used in a hydraulic dynamic test bench, belonging to the technical field of vibration cylinder monitoring. Background technique [0002] In the key equipment evaporator and main pump due to the coolant system, the hydraulic damper has little damping for this spatial position change. Once a pipe breaks or a strong earthquake occurs, the damper's blocking valve is quickly closed to damp the piston in the hydraulic cylinder. The flow of oil between the front and rear chambers stops, making the hydraulic damper instantly become a hydraulic spring. The rigidity of the cylinder block and the elasticity of the damper buffer the impact of broken pipes or earthquakes, and play a role in safety protection for the steam generator and the main pump. After rigorous theoretical calculations and model tests, the accident load that the hydraulic damper should bear in the ev...
