对注塑机五铰链斜排双曲肘增力机构进行了运动和力学特性分析，采用遗传模拟退火算法对该增力机构进行了优化设计，以机构行程比较大、力的放大倍数较大和机构总长较小为目标函数建立了优化数学模型，该优化设计属于多目标函数优化问题，通过对增力机构实例优化计算与传统设计方法进行了比较，结果表明行程比增加5．97％，力的放大倍数增加14．10％，机构总长减小5．25％。%The analysis of motion and mechanical property was carried out on a force increasing mechanism of injection machine which was five hinged incline arranged and double elbowed. A complete optimization design procedure was carried out using genetic simulated annealing algo- rithms, so as to increase the stroke ratio and the amplification of the force, and to decrease the to- tal length of mechanism. Its optional mathematics model was established. The procedure of opti- mal design belongs to multi-object optimization problem. The optimal solfition of the force increas- ing mechanism was found with genetic simulated annealing algorithms. Compared with the tradi- tional methods, the stroke ratio was increased by 5.97%, the amplification of the force increased by 14. 10 %, and the total length of mechanism decreased by 5.25%.
