Optimized Analysis on Structural Parameter for Planetary Roller Screw

The transmission principle of the planetary roller screw is analysed,and then several structural parameters of planetary gear in the planetary roller screw as the design variables are confirmed.At last,optimal analysis of these design variables is carried out by the multiplication-division and the simulated annealing algorithm,so design cycle is shorten and design cost is reduced on condition that the quality of design is premised.
