为研究并联坐标测量机的工作空间、控制算法和测量精度等 ,必须进行机构位置分析。测量模型的建立与求解是机构位置分析的正解问题。为降低位置分析难度 ,设计了基于演化Stewart平台的并联六坐标测量机。分别采用等效机构法和三维搜索法建立了测量模型 ,并通过计算机仿真获得了测量模型的解析解和数值解。仿真结果验证了两种建模方法的正确性。
In order to study the working space, control algorithm and measurement accuracy of the parallel coordinate measuring machine, the position of the mechanism must be analyzed. The establishment and solution of the measurement model is a positive solution to the position analysis of the institution. In order to reduce the difficulty of position analysis, a parallel six-coordinate measuring machine based on the evolution Stewart platform was designed. Equivalent mechanism method and three-dimensional search method were respectively used to establish the measurement model, and the analytical solution and numerical solution of the measurement model were obtained by computer simulation. The simulation results verify the correctness of the two modeling methods.
