摘要:

在以并联机构为主体机构的高频柔性并联振动台中,主体并联机构的运动学性能直接影响和决定振动台的激振性能。利用旋量理论综合出了一种新型三平移3-PPRR空间并联机构,并对其进行了自由度、主动副判定和运动学位置分析,利用MATLAB软件对其理论计算进行了建模仿真计算,通过Pro/E软件和
ADAMS软件联合仿真对并联机构进行了自由度和运动学位置解验证。

关键词: 高频柔性振动台, 并联机构, 螺旋理论, 型综合, 运动学分析, 仿真

Abstract:

The performances of a parallel mechanism are the basic of  a high frequency compliant parallel vibration actuator.Based on the screw theory,
a novel 3-PPRR parallel mechanism with 3 translational displacements was designed,
which was used in a compliant parallel vibration actuator.Then the degree of freedom
and actuating pairs and kinematics of the novel mechanism were analyzed.The models of the mechanism were established by MATLAB and Pro/E software.The  degree  of  freedom
and kinematics were analyzed by MATLAB software and simulated by ADAMS software.

Key words: high frequency compliant vibration actuator;parallel mechanism;screw , theory;type synthesis;kinematic analysis;simulation
