【摘要】 根据工程多维振动模拟的需要,设计了一种非对称全柔性3-RRRP微动并联激振台机构。在普通非对称3-RRRP并联机构基础上,将机构中的普通关节全柔性化,形成新型全柔性微动并联机构,在全柔性并联机构的主动件处施加单自由度的压电陶瓷激振器,设计出全柔性的多维微动激振台,经理论分析,发现该振动台具有三平移的微振动模拟输出。最后,对之进行了ADAMS软件仿真模拟,模拟结果显示,此种全柔性多维微动激振台可以以单层结构实现不同方向单自由度的平动振动模拟,也可以实现多维(二自由度或三自由度)微动振动的模拟输出,且激振输入与振动输出运动学完全解耦,具有相同的振动规律与振动频率,容易控制。更多还原

【Abstract】 It is designed a new fully compliant 3-RRRP parallel micro-displacement vibration actuator.All the joints in the traditional 3-RRRP parallel mechanism are changed into fully compliant ones.Theoretic analysis shows that the fully compliant mechanism will transfer into micro-displacement vibration actuator if adding single freedom vibration actuators to the traditional inputting components.The results are simulated with ADAMS software.The simulation shows that the fully compliant 3-RRRP parallel micro-displacement vibration actuator could simulate different translational vibrations with one freedom,two freedoms,three freedoms.Not only the actuator input and vibrtation output are all decoupled Kenimatically,but also have the same vibration rules and frequencies.更多还原
