Abstract

The invention discloses an impact test device and a method for conducting an impact test on a product. The impact test device comprises a tooling member used for testing and a vibration table used fortransmitting impact energy to the tooling member. The tooling member comprises a first component and a second component which are arranged oppositely. The first component comprises a first mounting plate and first and second sidewalls extending from the first mounting plate to the second component. The second component comprises a second mounting plate and third and fourth sidewalls extending from the second mounting plate to the first component. The end surface of the third side wall is connected with the end surface of the first side wall, and the end surface of the fourth side wall is connected with the end surface of the second side wall. A first connecting mechanism is arranged on the inner surface of the first mounting plate, and the first connecting mechanism is used for connectinga hanging frame carrying an object to be tested. The outer surface of the second mounting plate is provided with a second connecting mechanism used for being connected with the vibration table. The vibration table is connected with the second connecting mechanism of the tooling member.

Description

technical field [0001] The present application relates to the field of impact test devices, in particular, to an impact test device and a method for performing impact tests on products. Background technique [0002] Military external equipment such as missiles and pods will experience various impact environments under the mission profile of the aircraft, especially when the aircraft is mainly subjected to low-frequency impacts caused by ground cushioning and airflow during take-off, landing, and flight, the external equipment will be damaged. Therefore, it is necessary to conduct an adaptability assessment of the low-frequency impact environment for the external assembly including external equipment and racks. [0003] Ground test is an effective method and necessary link often used in the development stage of aerospace products. At present, the vibration table with high integration and complete control system is mainly used to assess the low-frequency impact environment of...
