Evaluation of the Strength Characteristics of a Certain Type of Reinforced Composite Material Launch Tube

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.
