Abstract

In order to get higher peak acceleration, strong shock test is carried out on conventional drop shock test table. Energy loss and collision coefficient are considered, the kinematic model of rebound collision shock amplifier is established by combining the dynamic contact theory with the classical collision theory, and the formulas of acceleration and its magnification factor are deduced. The influence of reserved clearance and elastic rope stiffness on shock amplification are discussed. Then, the experimental device is designed, and the feasibility of the theoretical model is verified. The results indicate that theoretical calculation is consistent with experimental results, and the maximum error is about 7%. The maximum acceleration can reach 3780 g, and the peak acceleration of the drop table is amplified by approximately 13.5 times. There is an ideal reserved gap to maximize the peak acceleration of amplifier, the larger drop height and ideal reserved gap are more conducive to shock amplification. The elastic rope with lower stiffness has a certain amplifying effect on acceleration, but its influence is small compared with the reserved gap.
