摘要
为提高分布式并联调姿机构的对接精度,减少系统误差的影响,从机构布放误差、参数测量误差和机构控制误差3个方面分析了误差原因,并定量分析了各误差的影响程度。以船舶大型推进轴系为例,搭建了船舶轴系对接试验台架,验证了误差分析的正确性,为复杂环境下的圆柱类大型零部件的高效、高精度对接装配提供了参考。
In order to improve the docking accuracy of the distributed parallel attitude adjustment mechanism and reduce the influence of system errors,the causes of errors were analyzed from three aspects:mechanism placement error,parameter measurement error and mechanism control error,and the influence degree of each error was quantitatively analyzed.Taking the ship’s large-scale propulsion shafting system as an example,a ship’s shafting docking test bench was built to verify the correctness of the error analysis and provide a reference for the efficient and high- precision docking and assembly of large cylindrical parts in complex environments.
