摘　　要：紧密结合并联机构应用于天线座架的任务要求,研究了影响应用于天线座架的Stewart并联机构构型的主要因素,建立了构型的优化原则,得到了并联天线座架方位俯仰转角与机构铰链摆角及杆长的关系,并给出了计算实例,验证了构型优化原则的正确性。面向实际任务进行机构设计,研究内容对于Stewart并联机构真正应用于天线座架具有重要的理论指导意义。The major factors affecting the antenna mount by the mechanism have been examined in combination of the mission requirements when Stewart parallel mechanism is used in antenna mount.The principles to optimize the mechanism are established to acquire the relationship among the elevation angle of the antenna mount,the tilt angle of the hinge mechanism and the length of the rod and in addition the calculation examples are given to verify the correctness of the principles for mechanism optimization.All of them present important theoretical and directive significances in application of Stewart parallel mechanism to a real antenna mount.
