Kinematical Analysis and Simulation of Gear Parameter Laser Measurement System

The motion stability and reliability of laser measurement system for gear parameters are the most important factors to ensure its measurement accuracy. The solid modeling for this measurement system was built by using Solid-works in this paper to know its kinetic characteristics,Denavit-Hartenberg notation was applied to establish the coordi-nates system for each movement joint and proceed the kinematics analysis. Robotics Toolbox in Matlab was utilized to configure the kinematic model for this system and the kinematics simulation and the trajectory planning simulation for movement joints were conducted. The movements of the measurement system in the process of measuring can be seen more clearly through the simulation results, and the simulation of the trajectory planning has verifiedthe reliability and stability of the measurement system.
