大功率伺服系统传动链的刚度、齿隙量、转动惯量、厍仑摩擦力矩、粘滞阻尼等结构因素对系统工作性能会产生较大的影响。因此伺服机械的设计,不能采用传统的纯机械设计的方法和原则,需从机电结合的角度出发,寻求新的设计准则,以保证系统的性能满足要求。在理论方面,目前已开展了不少工作,但在实践方面未见到系统的探索。西北电讯工程学院最近研制成功的“伺服系统结构因素模拟试验台”提供了一个有效而可靠的物理模拟手段。我们用以正交试验法设计了试验方案,试验结果比较令人满意,达到了予期目的:(1)
The structural factors such as stiffness, backlash, moment of inertia, friction torque, viscous damping and other structural factors of the transmission chain of high-power servo system will have a greater impact on the system performance. Therefore, the design of servo machinery can not adopt the traditional methods and principles of purely mechanical design. It is necessary to seek new design criteria from the perspective of electromechanical integration to ensure the system performance meets the requirements. In theory, a lot of work has been done at present, but there is no systematic exploration in practice. Northwest Telecommunications Engineering Institute recently successfully developed “servo system structural factor simulation test bed” provides an effective and reliable physical simulation. We use the orthogonal experimental design of the test program, the test results are satisfactory, to achieve the intended purpose: (1)
