Li Dahai, Song Shengtao, Li Ruiqin, et al. Research of the Reachable Workspace of Symmetrical Planar 3-RRR Parallel Mechanism[J]. 2015,39(9):29-31. DOI: 10.16578/j.issn.1004.2539.2015.09.007.
By using the method of closed vector,the position positive solution model of the symmetrical planar 3- RRR parallel mechanism is built. Aiming at the typical example( for the frame is the longest and all the rods connecting frame are cranks),with the help of the numerical method to solve and the reachable workspace of 3- RRR parallel mechanism is mapped by using the Matlab,and compared with the result gained by motion simulation of virtual prototype software Solidworks.
