摘要
从手控器的功能需求出发,针对实验室原有设备设计了三自由度手控器,能够实现X,Y,Z三个方向的平动自由度。在完成了手控器详细结构设计与驱动部件的选型后制作了它的工作动画,同时进行了主要结构件在一定工况下的CAE分析。在实际工作中,一方面,操作者通过控制手柄来实现对手控器的操作,安装在并联机构主动端的编码器检测中间杆的转动角度,通过运算器正解得出动平台相对于固定参考点的平移距离,通过信息传输给终端,终端设备接受信息并以此为标准控制远端设备的工作,如机械手的运作等;另一方面,远端设备与环境相互作用的过程中产生力的作用,通过传感器检测信号并传输给操作端,操作端接收信号并通过运算器静力学计算得出力矩,各支链的电机根据运算得到的力矩运转通过传递将力传给操作者以实现力的反馈。

Abstract
Based on the functional requirements of the manual, three degrees of freedom hand controls are designed for the original equipment of the laboratory, and the translational degrees of freedom in X, Y and Z directions can be realized. After completing the selection of the detailed structure of the hand control and the selection of the driving parts, the work animation was produced, and the CAE analysis of the main structural parts under certain working conditions was carried out. In the actual work, on the one hand, the operator realizes the operation of the controller through the control handle. The encoder mounted on the active side of the parallel mechanism detects the rotation angle of the intermediate rod. The operator is satisfied that the translation distance of the moving platform relative to the fixed reference point is transmitted to the terminal through the information. The terminal device accepts the information and controls the operation of the remote device, such as the operation of the robot. On the other hand, the remote device and the environment interact with the process of generating the role of force. The signal is detected and transmitted to the operator by the sensor. The operator receives the signal and calculates the torque by the operator. The motor of each branch is transmitted to the operator to transmit the force according to the calculated torque.
