中文摘要：

首先阐述了转台轴承应拉开合适的间距且装配时使轴承的偏心量同向,及直流力矩电机的选取方法,又给出了三轴仿真转台主要载荷的工程计算方法,然后在ADAMS2003中仿真3个框架分别单独摇摆及分别匀速转动时驱动电机输出转矩情况,再仿真3个框架同时摇摆及同时匀速转动时驱动电机输出转矩的耦合情况,最后进行实验测试,并将实验结果与仿真结果、工程计算结果及最终选取结果进行对比分析,得出3个框架同时转动时,会引起框架间力矩的耦合,驱动电机输出转矩会增加,不考虑3个框架耦合作用的工程计算结果是不准确的,工程设计中选取驱动电机必须以ADAMS中的仿真结果为依据,这就为实际设计中选取驱动电机及进一步的研究工作提供了依据。

英文摘要：

First, the method for pulling the motion simulator bearings to a proper interval, keeping the eccentric amount of bear- ings in the same direction during assembly and selection of DC torque motor were explained, and engineering computation method of major loads in three-axis motion simulator is presented. Then, simulation calculation of the motor output torques has been comple- ted in ADAMS 2003 when three frames swinging and rotating at constant speed individually; the motor coupling torque was also computed when swinging synchronously and rotating at constant speed. The test experiment has been finished. According to the comparison of results from the simulation, the experiment and the engineering computation, a conclusion was drawn that the selection of driving motor in design must be based on simulation results in ADAMS, because the engineering computation results without tak- ing the coupling impact between three frames into consideration are not accurate, where the coupling impact of torque in three frames leads to an increase in motor output torque when three frames rota- ting synchronously, which provided a guideline for driving motor se- lection and paved the basement for the further research.
