...Ligang Lu; Pengfei Li; Dongbo Wu; Jiawei Liang; Hui Wang; Pengpeng He Purpose The purpose of this study is to establish an assembly accuracy analysis model of deployable arms based on Jacobian–Torsor theory to improve the assembly accuracy. Spacecraft deployable arm is one of the core components...

... with skin modeling considering SDCPSM and LSD of mating surfaces, which can help to improve the accuracy of tolerance analysis. The geometry of a real machined part inevitably deviates from the ideal conditions in the manufacturing process and further influences on the product assembly accuracy. To ensure...

...Xin Ye; Pan Liu; Zhijing Zhang; Chao Shao; Yan Li Purpose – The purpose of this paper is to analyze the sensitivity of the motion error parameters in microassembly process, thereby improving the assembly accuracy. The motion errors of the precision motion stages directly affect the final assembly...
