Abstract

The invention discloses a multifunctional strong shock simulating testing device and method, and relates to the technical field of pneumatic shock equipment. The device comprises a power device, a sliding worktable top, a front baffle, a front baffle buffering cushion, a rear baffle and a rear baffle buffering cushion, wherein the front baffle and the rear baffle are oppositely arranged; a pair ofmutually-parallel slide rails is arranged between the front baffle and the rear baffle; each slide rail is sleeved with at least one linear slide block; the sliding worktable top is arranged on the linear slide blocks in a screwing manner; the front baffle buffering cushion and the rear baffle buffering cushion are correspondingly arranged at the inner side of the front baffle and the inner sideof the rear baffle. According to the multifunctional strong shock simulating testing device and method, a shock response spectrum shocking platform or a high-speed shock cylinder is used for supplyingshock power to the sliding worktable top, and thus twice classic shocks in positive direction and negative direction can be realized by once shocking, and the shock acceleration waveform can be amplified; and moreover, the classic shock and complex instantaneous shock in one direction can also be realized.

Description

technical field [0001] The invention relates to the technical field of pneumatic impact equipment, in particular to a multifunctional strong impact simulation test device and method. Background technique [0002] Weapons and some high-reliability electromechanical products and equipment have to withstand thousands of g of shock overload (g refers to the acceleration of gravity) during their working process. An important means of product and equipment reliability. [0003] At present, the pneumatic horizontal shock response spectrum shock table and the pendulum shock response spectrum horizontal shock table can generate complex shock shock acceleration waveforms through the impact of the energy weight on the shock acceleration table (shock response plate), which are often used to assess the shock response characteristics and Vibration and shock resistance. However, due to the slow speed of the energy weight hammer, the amplitude of the shock acceleration generated by hittin...
