Embodiment Construction

[0052] The armored vehicle seat bench test adopts the drop impact test scheme to test the anti-mine explosion impact performance of the armored vehicle seat. The anti-mine seat is installed inside the rigid frame to simulate the installation method of the seat in the armored vehicle, and the rigid frame is dropped to generate shock waves. shape to realize the simulation of explosion impact. The explosion shock waveform generating device is fixed on the ground, and the shock waveform simulation is realized by vertically colliding with the rigid frame on which the lightning protection seat is installed, and the waveform curve of the shock acceleration is used as the criterion for judging the success of the simulated waveform.

[0053] Such as figure 1 As shown, the armored vehicle seat platform includes a test bench 1, a rigid frame 2, an explosion shock wave generator 3, a high-speed camera 4 and a lifting device 5. The lifting device 2 is installed on the beam at the top of t...

Abstract

The invention belongs to the field of seat performance tests, and discloses an explosive shock waveform simulation system and method for an armored car seat bench test. The explosive shock waveform simulation system for an armored car seat bench test comprises a test bench, a rigid frame, an explosive shock waveform generation device and a lifting device. The lifting device is installed on a top crossbeam of the test bench. The rigid frame is connected with the lifting device. A test piece is arranged in the rigid frame. An explosive shock waveform generating device is installed on the groundof the test bed. The armored car seat bench test adopts a drop impact test scheme to carry out the landmine explosion impact resistance of the armored car seat, the lightning protection seat is installed in the rigid frame to simulate the installation mode of the seat in the armored car, and the rigid frame drops to generate an impact waveform to realize the simulation of explosion impact.

Description

technical field [0001] The invention belongs to the field of seat performance tests, and in particular relates to a simulation system and method for explosion shock waveforms of an armored vehicle seat bench test. Background technique [0002] With the significant increase in the threat of landmines and improvised explosive devices faced by armored vehicles in battlefield driving and peacekeeping missions in recent years, all countries have strengthened research on the comprehensive protection of armored vehicles. For the protection of the occupants, the most important thing is the lightning protection seat, because it can weaken the transmission of shock waves through its own cushioning design, and has become the last level of protection for the life of the occupants of armored vehicles. Therefore, the research on anti-mine explosion impact seats has been carried out successively at home and abroad. Although at this stage, most manufacturers and institutions have accumulat...
