摘　　要：多杆件并联及串并联型机床是正在致力研究和开发的新型加工设备。分析了一种新研制的串并联型机床的结构及空间误差 ,推导并验证了主轴平台空间运动误差的数学模型 。Machine tools with the parallel arrangement of struts are being developed for industrial production. In order to evaluate the static acc-uracy,the error analysis of a serial-parallel type machine tool is presented. Different methods are adopted to derive the error model, namely the linkage kinematic analysis and the differential vector method, by which the effects of strut manufacturing tolerance and actuating error on the tool position and pose are investigated. The computational results show the influences of the actuating error and the strut length error on the machine tool accuracy.
