A Rocket Launcher Lifting Mechanism Of Structural Design And Research

In this thesis, an elevator machine is designed in order to increase the attacking area by promoting the rocket launcher during the launching period with the machinery design theory and knowledge, then the dynamic simulation and nonlinear structural dynamics analysis of the elevator machine are studied respectively by use of the Recurdyn dynamics software and the ABAQUS finite element software with the nonlinear finite element theories and multi-rigid-body dynamics theories, in order to check the correctness of the elevator equipment design.The main aspects of this thesis are as follows: First, the elevator machine type is chosen according to the tactics request of rocket launcher, and the structural parameters of the elevator machine are calculated. The three-dimensional entity model of the elevator machine is built applying the three-dimensional software, i.e. Solidworks to make foundation for further investigation. Second, the working process of the elevator machine is simulated by building entity model in Recurdyn dynamics software, making sure some member movement parameters can meet the tactics request of rocket launcher. Third, according to finite element analysis theory, finite element method model of the elevator machine is built in ABAQUS software. Adopting obvious dynamics method, dynamic response analysis of the rocket system with elevator machine and without it are carried out on rocket launcher system during firing under firing conditions of 0 degree of direction, 0 degree of elevating angle and 30 degree of elevating angle. The checkout on the intensity and stiffness of the elevator machine is carried out.
