According to the analysis of location and motion parameters of swing cylinder eight一bar mechanism,a mathematical model was built to design and optimize the eight一bar mechanism.Based on the Simulated Annealing Algorithms,an intelligence optimization method was proposed to ensure the mechanism the minimum error of swing angles and bar lengths.Some critical problems were solved,such as modeling constraint conditions of multi-bar length and design of neighborhood search strategy.Finally,a simulation program was applied to estimate the method and according to the results,the method is of a good performance of global research and can be applied to the design and analysis of multi-bar mechanisms effectively.
