Motion Planning and Simulation of Dental Arch Generator

JIANG Jin-gang,ZHANG Yong-de(Intelligent Machine Institute,Harbin University of Science and Technology,Harbin 150080,China)  
Aiming to the characteristics of coordinated control for dental arch generator,motion planning of dental arch generator is studied.Based on power function model of dental arch,dental arch generator is established.Control point positions of dental arch generator are calculated by the arc length constant theory.Dental arch parameter equal increment method is proposed to realize motion planning of dental arch generator.The results show that the maximum von mises hot spots of method 3 for the dental arch generator is small compared to other methods.The experimental motion trajectory of the dental arch generator is approximately in agreement with the simulation and theoretical motion trajectory.The results prove that it is feasible to realize motion planning of dental arch generator using the dental arch parameter equal increment method.
