提出一种2-PSS&PPU并联微动机器人机构。利用螺旋理论分析了该机构末端执行器的自由度,并推导出其工作空间理论范围。最后通过一个完整算例,基于MATLAB软件搜索机构工作台的运动边界,从而计算出机构工作空间,证明理论推导的正确性。在进一步的分析中,可以确定当限制某个驱动杆件长度时,可以对工作空间产生影响,为该机构的运动学和动力学分析奠定了基础。
Proposed a new parallel micromanipulator. Analyzed its degree of freedom on screw theory, and deduced the workspaee. Searched the boundary curve of workspace based on the Matlab by a sample, and validated the inference. Determined that the workspace can be affected by the driving linkage. Laid the foundation of kinematic and dynamic analysis.
