为提高陶瓷抛光机磨头凸轮驱动部分的动态性能，以最大无因次加速度为目标函数，建立了磨头凸轮曲线优化模型，运用MATLAB软件的功能函数constr求得优化结果。优化后最大无因次加速度为优化前的33％，和原有曲线相比下降了30％，可以有效的降低磨头的振动及故障率，提高陶瓷地砖加工的表面质量，降低震碎率。 To improve dynamic capability of grinding head cam mechanism of ceramic polishing machine, taking the maximum non-dimensional acceleration as objective functions, the paper buih up optimization model of grinding head cam curve and obtained optimized resuhs with MATLAB software computing function constr. The maximum non- dimensional acceleration was only 33% of pre-optimization can effectively reduce the vibration and failure rate of and lower by 30% compared with the original curve, thus grinding head, as well as can get better surface quality, lower shatter rate in the processing of ceramic tile.
