Problems solved by technology

[0003] At this stage, most of the drop hammer test devices use electric motors to drive the lifting hammer. The transmission process requires reducers, wire ropes, pulleys, etc. The positioning accuracy of the drop hammer is low, and it takes up a lot of space, which is not convenient for laboratory layout and operation.
In addition, when the heavy hammer falls and rebounds, if the heavy hammer that is about to fall again is not caught, a second impact or multiple impacts will occur.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with drawings and embodiments.

[0016] Such as figure 1 , first of all, the system needs to have actuators and control elements that can lift the weight, position at any height and hold the hammer twice; secondly, in order to realize automatic operation, it needs a controller and position detection sensor; finally, in order to improve the man-machine interface, A touch screen and an upper computer are required to communicate with the controller.

[0017] As the core of the control system, PLC directly completes the coordinated control and motion position detection of each component of the device. It is equipped with a touch screen as an on-site debugging device, and can also remotely control and monitor the operating status of the system through a computer. The stepper motor drives the precision ball screw to perform arbitrary height positioning, combined with the grating scale for closed-loop contro...

Abstract

A drop hammer type pressure generator pneumatic control system uses a PLC as the core so as to control a motion process, thus improving the operation automation of the test process, improving man-machine communication, and enabling the drop hammer type pressure generator to satisfy system precision requirements; the drop hammer type pressure generator can be compact in structure arrangement, and less in land occupation; the pneumatic control system is reliable in work, can satisfy test requirements, can be applied to the drop hammer type pressure generator, and is suitable for other drop hammer type impact test device designs, thus providing certain reference values.

Description

technical field [0001] The invention relates to a pneumatic control system of a drop hammer type pressure generator, which is suitable for the mechanical field. Background technique [0002] The drop hammer test device is mainly used for simulation tests under impact conditions, providing impact loads for the tested parts or equipment, such as generating transient pressure sources, or performing impact tests on various new engineering materials, pyrotechnics, and dampers. Its working principle is to convert the potential energy of the hammer into kinetic energy after release, and generate impact load at a certain impact speed. It is a test device with reliable operation, good repeatability and low test cost. Utilize the kinetic energy of the falling weight to impact the oil in the closed volume, and generate a pressure source similar to a semi-sine pressure wave, with a maximum pressure of 600MPa, which can be used for pressure calibration of various high-pressure sensors. ...
