Optimization designand kinematic analysis of planar linkages based on matlab

Linkages can effectively achieve the given motion or trajectory, and nicely complete the intended action, so it is used widely in such fields as mechanical and instrumentation applications. In this paper, we presented optimization design method of plane linkage given trajectory under many constraints based on Matlab Optimization Toolbox functions. Mathematical model for optimum design of four-bar mechanism is established according to the design requirements and characteristics. Optimization design using computer software to get a more satisfactory institutional design in all respects and simulation analysis optimization design for crank-rocker mechanism under influence of conditions is met. The results showed that design cycle can be shorten, the design quality and design precision be improved, and the simulations of motion have good feedback and validation using optimization method. At the same times, the method provides a reference for optimization and simulation of multi-bar linkage and other mechanism design. © Sila Science. All rights reserved.
