摘要: Abstract In this paper, shock isolation performance of a geometric anti-spring (GAS) isolator is investigated. The static and dynamic stiffness property GAS discussed. mathematical simulation used to explore the effect several parameters on under modified half-sine pulse acceleration excitation. Shock experiments base excitation with different amplitudes payloads are carried out. results show that characteristic determines its performance. When amplitude not too large, shows better absolute displacement than equivalent linear system. effects amplitude, payload, damping discussed, which provide guidelines for further practical application.
