Topology Optimization of Passive Shock Isolator with Application to Ballistic Shock
초록
Topology optimization of improved passive shock isolator by controlling its force-deflection relation is proposed. And the final design which is optimized using topology optimization is obtained using shape optimization. The proposed methods are applied to a numerical example using two dimensional-axisymmetric condition. And the performance of finally optimized design is verified through transient analysis using LS-DYNA. The ballistic shock isolator model is developed as a result of topology optimization. The optimized design has more improved shock absorbing capability comparing to the linear shock isolator by about 20%.
