摘要
为了评估复合材料发射筒的设计是否满足使用要求,建立了某型复合材料发射筒的三维有限元仿真计算模型,并对该型发射筒在吊装、运输、发射工作状态下的受力与变形情况进行了分析评估,得出该型复合材料发射筒在这些过程中的最大变形,采用最大应力准则推导出复合材料发射筒的最小安全系数。评估结果表明:3种工况下,该型复合材料发射筒的最大变形为1.93 mm,最小安全系数为1.63,采用一体成型工艺设计的复合材料发射筒的强度能够满足使用要求。
In order to evaluate whether the design of the composite launch tube meets the requirements,a three-dimensional finite element simulation model of a certain type of composite material launch tube is established,and the stresses and defor⁃mations of the launch tube are analyzed and evaluated under the working conditions of hoisting,transportation and launch⁃ing,and the maximum deformations of the composite launch tube during hoisting,transportation and launching processes are obtained.The minimum safety factor of the composite launch tube is derived.The evaluation results show that the maximum deformation of the composite launch tube is 1.93mm and the minimum safety factor is 1.63 under the three working condi⁃tions,the strength of the composite launch tube designed by the integral molding process can meet the requirements of use.
