以水下爆炸试验光学测量为研究背景,在水下近场爆炸冲击波作用下光学设备防护平台结构设计的基础上,通过传统的理论经验计算与计算机数值仿真计算方法,对防护平台结构的运动特性进行分析并校核。结果表明平台结构的运动响应满足光测设备和试验需求,验证了防护平台结构设计的合理性;防护平台结构背爆面的密封位置可向中部偏移以提高平台结构遭遇冲击波作用时的稳定性。

Under the background of optical measuring in underwater explosion test,and on the basis of the structure design of optical measurement defense platform subjected to underwater explosion blast wave,the kinematics characteristics of defense platform were analyzed and checked by theoretical calculation and numerical calculation methods. The results showed that the kinematic response of platform structure satisfies the needs of optical measurement and test; and the results verifies the rational of platform structure design. It can improve the stability of defense platform subjected to underwater explosion blast wave that the sealer location properly moved to central section.
