Kinematics and Dynamics Simulation of Certain Type Radar Multi-linkage Lodging Mechanism

Aiming at the problems of light weight, miniaturization, and limited space of certain type radar lodging mechanism, proposes a solution to the dual-rocker multi-linkage lodging mechanism, and this solution adopts closed vector principle and auxiliary geometric solution method for design analysis. Use the computer-aided tools Matlab/Simulink and SimMechanics to establish a 3D dynamic simulation model, carry out the dynamic simulation and optimization design of mechanical and electrical integration of the mechanism, and get the angle, speed, acceleration and driving force curve results of the original rocker revolute pair and the driven rocker revolute pair respectively. The simulation results show that the method fully demonstrates the motion and dynamic characteristics of the linkage lodging mechanism, verifies the feasibility of its design, and provides important basis for the design of the transmission structure and control system.
