Each hydraulic link of 6-DOF parallel robot is treated as an open joint-link chain. Each link's local coordinate frames is established according to the position and orientation of the component of the spatial mechanism. The stiffness and damping matrices of the link are transformed into the static gross coordinate frame through transfer matrix described by the RPY description method. The differential equation of motion of the system vibration is derived.

将6-DOF并联机器人的液压分支作为假想的单开链，由空间机构的位姿建立其组成构件的局部坐标系，并利用RPY角描述方法，通过转移矩阵将各构件的刚度及阻尼矩阵依次转移到固定坐标系中，得到了系统振动的运动微分方程。

In this paper dimension-chain is used to calculate the last effective dimension formed under the influence of tolerances and other distortions. Feature modeling is applied to construct the three-dimension mode of the parts in solidworks. Based on the parametric design function, simulation of assembling result is realized by making use of VB to develop Solidworks. The accomplish of variable parametric design system in tolerance designing is realiazed.
