摘要：

平行双关节坐标测量机是一种新型非正交坐标测量设备. 文中利用改进四参数DH模型导出平行双关节坐标测量机的测量模型，在此基础上建立该坐标测量机的误差模型. 利用测量机的误差模型验证测量模型的正确性，并与理想模型进行比较. 该方法为进一步研究平行双关节坐标测量机的设计和误差分配提供了理论基础.

Abstract:

Double parallel-joint coordinate measuring machine (CMM) is a new type of coordinate measuring devices. An improved four-parameter DH model is used to deduce the double parallel-joint CMM measurement model. Error model of the double parallel-joint CMM is discussed based on the measurement model. Compared with the ideal model, correctness of the measurement model is verified by the error model. This forms a theoretical basis for designing and error distribution of double parallel-joint CMM.

Key words: coordinate measuring machine, mathematical model, DH model
