A new subject named mechanism optimization design had been formed when it was combined with mechaism design and computer technique . " best optimization " is the goal of almost every designer or engineering project . in any design of engineering or product , the goal of best design was wanted by choosing a reasonable scheme or confirming parameters according to the requests of design . so , optimization design has good prospects of development and the appliance in the field of mechanism design 机械设计与最优化技术、电子计算机技术相结合，形成了机械优化设计这一新领域。 “最优化”是每一个工程或产品设计者所追求的目标。任何一项工程或一个产品的设计，都需要根据设计要求，合理选择方案，确定各种参数，以期达到最佳的设计目标。
