摘要:
对并联加工机床的6-6 Stewart并联机构动态加工过程进行了分析,利用螺旋矢量方法建立了机床6-6并联机构刚度数学模型,计算了动态瞬时刚度和刀具的偏移误差,并开发了应用软件,对6-6并联机床结构在多种不同参数变化条件进行了数值模拟。研究结果可为机床精确控制和实时标定提供算法,对优化机构设计、工作空间设计及载荷设计和布置提供理论依据。
Abstract:
The investigat ion is carried out into the too ling process of a 6-6 S tew art para llelmachine too lw ith dynam ic fea tures. The der ivation into the instantaneous 6-6 paralle l structure stiffness mathematicalmodels is performed. The ca lculation simulat ion resu lts in the stiffnessm atrix and cu-t ter deflections during too ling process. A se l-f deve loped softw are system has packaged numerica l simu lations to enab le the var iety of different structure parameters and tooling condit ions. The results prov ide the a lgorithms fo r control and calibrations on themachining accuracy and the theoret ica l info rmation for opt imum configurat ion, workspace and load ing.
