Structure Design And Optimization Of Automatic Transmission Of Missile

The requirement of modern war on the degree of automation artillery is higher and higher, ammunition autoloader technology will play an increasingly large role in the future battlefield. As a key subsystem of the ammunition autoloader, the autoloader manipulator will have a great impact on the performance of the artillery. Therefore, it is of great significance to study the ammunition autoloader technology and develop the autoloader manipulator. In this paper, with the background of the development of a multi-function artillery test bench, designed reasonable structure to meet the function of the autoloader manipulator, and carried on the analysis and optimization of it, the main contents of this paper are as follows:1.Designed the structure of the manipulator according to the required function of it, used Pro/E software to establish the three-dimensional model, the key parts of the structure and function of the principle were described in detail. The transmission device of each joint was calculated, and the selection of motor and reducer was finished.2.D-h method was used to construct the manipulator kinematics model, substituted into the structure of the specific parameters, the kinematic equation was obtained, and the equation of the inverse solution. Used Robotics Toolbox in MATLAB software to establish the manipulator model, verified the correctness of the kinematics equation, proceed planning and simulation of the motion trajectory of each joint of the manipulator.3.Used Lagrange method to establish the dynamic equations of the manipulator. According to the use of virtual prototype technology, built the dynamic model of the manipulator in ADAMS. The whole working process of the manipulator simulation obtained each joint motion curve and the joint driving torque or force, analyzed the changes of the contact force between the holding claw and the wedge, projectile.4.Based on Optistruct platform, topological optimization was taken on all the thickness of the steel plate of rotary bracket, size optimization was taken on the structure of holding claw. Under the situation of satisfying constraints, reduced the use of material, reduced the weight of the manipulator, improved the working performance of the manipulator.
