THE COMPUTER AIDED DESIGN OF SPATIAL LINKAGE WITH THE GIVEN RANGE OF OUTPUT-LINK MOTION

When the motion range of output-link of the spatial linkage is required,it is difficult to meet this need hy using the.pure analytic methods in the design of the linkage. For this reason,the geometry search method based upon the AutoCAD software is presented in this paper. It is simple,convenient and audio-visual.and is easy to be applied in the practice. This design method and its appication are set forth in detail in this paper by taking the example of spatial RRRSR linkage design.
