A parallel mechanism with two translational and one rotational degree of freedom is designed.its structure characteristics

such as freedom number and output motion type

are investigated.and inverse and direct solution of position analysis are given.3D solid model and its kinematics simulation of the parallel mechanism are performed by SolidWorks and CosmosMotion which is a kinematics analysis module closely integrated with SolidWorks.The results of analysis show that the parallel mechanism tend to accomplish real-time control

and its position analysis is easy to be carried out

so that it can be widely applied in the many fields

such as like industrial assembly robots

micromanipulators

virtual axis parallel machine

and multidimentional damping platforms.
