고중량 충돌 시험 대차의 구조 설계

In order to evaluate the safety of the impact load of the structure, impact test devices are used such as sharpy, lateral, hroizontal impact tester. And vareities of impact pulse are presented and modified in each country. Test table and impact table in shock machine are damaged during impact test. Damage of shock causes fatigue fracture. To study structural safety of impact load on test table, Changing shape can be on of the way. In this study, changing shape of test table is performed.
