中文摘要: |
针对工业设备快速抓取物件的需求,基于并联机构具有的优点,提出了一种二自由度可快速移动的并联机构。
对该机构的运动学进行分析研究,创建该平面二自由度的运动学模型,利用勾股定理推算出该机构的正反解,继而得到
雅克比矩阵。最后利用杆件约束等条件得到该机构的工作空间。通过SolidWorks和MATLAB仿真软件求正反解验证了
设计的正确性。该并联机构的横向位移较大,满足设计要求。 |
英文摘要: |
According to the need of industrial equipment grabing objects quickly and the advantages of parallel
mechanism, a new kind of parallel mechanism with 2-DOF was studied aiming at the characteristics of catching things
fast. Kinematic analysis was studied. The kinematic model of the mechanism was setting up, and the forward and
inverse kinematics were solved by the Pythagorean theorem. The Jacobian matrix was derived. The workspace which
conforms to the actual constraint conditions was obtained. The correctness of the forward and inverse kinematics was
verified by SolidWorks and MATLAB simulation software. The parallel mechanism has a larger horizontal displacement,
and it can satisfy the demand. |
