Abstract

Drop impact is an phenomena that object movement state arises sharp change when it gets strong wallop in a short time and is a chief reason for minitype electromechanical products appearance breakage and function failure. How to improve products, shock resistance and essential crashworthiness has been studied by domestic and foreign scholars for many years. Research status of products, shock resistance and crashworthiness robust design are recommended. Research techniques are systemically analyzed. And existential questions are summarized.
