| 摘 要： | 通过研究3RRR 并联机器人的平面机构特点，用数值方法对其运动学正解进行分析求解，并用解析法对其运动学逆解进行分析求解. 通过MATLAB 仿真，用Pro/E 建模加以验证. 在运动学逆解基础上，运用二维遍历搜索法得到3RRR 并联机构的工作空间. 结论表明，当动平台的旋转角度φ为0°时，其工作空间最大；当旋转角度φ为β/2 时，其工作空间最小.该方法可减小求解工作量，提高计算效率.

| Abstract: | By studying characteristics of planar mechanism of a 3RRR parallel robot, a forward kinematics problem is analyzed and solved numerically. At the same time, an analytical method is used to analyze and solve the inverse kinematics problem. With MATLAB for simulation and calculation, the results are built into a corresponding model by Pro/E for verification. Based on inverse kinematics, workspace of the 3RRR parallel mechanism is obtained by using a two-dimensional traversal search method. The conclusion shows that, when the rotation angle of moving platform is 0, the workspace reaches a maximum, and when the rotation angle is π/2, the workspace is a minimum. The method can reduce workload in solving the problem and improve computational efficiency. |
