Abstract

The invention discloses a simple pneumatic lifting and rapid releasing vertical automatic impact cylinder which comprises a high-pressure gas gun used for generating high-acceleration impact force, animpact cylinder body and a control cylinder. The impact cylinder comprises a cylinder body, a piston and a piston rod, the piston is fixedly mounted on the piston rod, and the piston is used for receiving high pressure generated by the high-pressure gas gun to drive the piston rod to move at a high speed in the cylinder body; the control cylinder is used for providing controllable braking for thepiston rod. The simple pneumatic lifting and rapid releasing vertical automatic impact cylinder can be suitable for realizing a high-acceleration impact mechanical environment test, the test condition is easy to meet, the cost is low, the use is convenient, and the excitation of the high-acceleration impact mechanical environment can be safely and reliably realized by multiple times of repetition.

Description

technical field [0001] The invention relates to the technical field of high-acceleration impact excitation tests in mechanical environments, in particular to a simple pneumatic lifting and quick-release vertical automatic impact cylinder. Background technique [0002] High-acceleration shock excitation technology is an important aspect in high-acceleration shock mechanics environmental tests. The excitation technology that uses the energy released quickly by compressed air to realize the high-acceleration impact mechanical environment has been practically applied in the Hopkinson compression rod technology and air cannon technology. The Hopkinson compression rod technology uses high-pressure gas to push the accelerated bullet to hit the transmission rod. Based on the one-dimensional stress wave theory of the transmission rod, a high-acceleration impact mechanical environment is obtained. The test piece is fixed at the other end of the transmission rod; the existing air canno...
