It indicates existent problem of traditional engineering design and recounts simulation argorithmic based on calculation method.With analysing characteristic of mechanism on machanics discretely, it recounts how to set up virtual prototype math model and computer model to implement mechanism simulation animation with programming. Based on this it also resolves virtual prototype output velocity ＆ acceleration curve with differential method in calculation method. From feedback of virtual prototype simulation, it achieves optimization design of mechanism transmission so as to enhance working efficiency. With double-slider mechanism virtual prototype technology on calculation method it breaks a new path for product design and extensive networked design ＆ manufacturing.
