| 摘 要： | 精密定位、精密测量领域中除了要求精密定位平台具有高的定位精度外,还要求平台具有小的运动耦合性.柔顺定位平台中柔性铰链的关键尺寸加工误差将会对平台的运动耦合带来影响,必须进行合理的尺寸精度设计.针对所设计的一种纳米级定位精度两自由度柔顺平台,分析了不同位置铰链加工误差对定位平台耦合的影响,确定了对耦合影响最大的因素,给出了平台铰链关键尺寸精度设计的建议.

| Abstract: | In the fields of precision positioning and precision measurement, both high positioning accuracy and small coupling of the platform are needed. Machining errors of the key dimensions of compliant mechanism, which is based on the compliant joints, will significantly effect the kinematic coupling of the platform. This paper designed a 2 DOF compliant nanopositioning platform, analyzed the coupling of the platform caused by machining error of different joints, then determined the main influence factor. The suggestions on tolerance design of key dimensions of the platform are put forward. |
