Research and Design of Rotating Speed Curve of Camshaft Spindle Based on Particle Swarm Optimization

In the process of constant angular speed grinding and constant linear speed grinding for camshaft workpiece, there are problems in which the speed, acceleration and jerk of each linkage servo system change drastically. This paper presents a polynomial motion law curve of tectonic spindle (rotary axis), designs a single-objective evaluation function with the rigidity requirement of the servo system of X-C linkage axis, and uses the particle swarm optimization (PSO) to solve the optimal solution of the objective function. The results show that the mechanical impact caused by excessive acceleration during the grinding process is greatly reduced, and the quality of high efficiency precision grinding of camshaft is greatly improved.
