【摘要】 提出了一种新型的空间3自由度并联机构,该机构的运动平台具有2个移动自由度和1个转动自由度。建立了机构位置的正反解,对机构的转动能力进行了分析,计算出机构动平台在空间运动时的转动角度。同时,可以使整个机构沿x、y方向移动,增加了机构的工作空间。更多还原

【Abstract】 A kind of new typed spatial 3DOF parallel mechanism was put forward. The moving platform of this mechanism has two translation DOFs and one rotation DOF. The positional forward and backward solutions of mechanism were established, and an analysis was carried out on the turning ability of mechanism. The rotation angles have been calculated while the moving platform of mechanism was moving in space. At the same time, it is possible to let the entire mechanism be moving along x and y directions thus increased the working space of mechanism.更多还原
