Kinematics Analysis Of A 3-Dof Hydraulic Driven Parallel Mechanism

In order to provide the basis about the selection of parts for the mechanical design of a 3-DOF parallel mechanism, such as hydraulic cylinders, valves and so on. Based on coordinate transformation and vector guidance method, the kinematics of the hydraulic drive 3-DOF parallel mechanism is analyzed at first. Secondly, deducing the displacement of each hydraulic cylinder according to the position of the upper platform on parallel mechanism. Then, The ADAMS is used to build virtual prototype of 3-DOF parallel mechanism, the validity about the kinematics of the parallel mechanism is verified by the co-simulation of MATLAB / SIMULINK and ADAMS, which provide the theoretical support for dynamics analysis.
