Abstract EN
The stiffness and elastic deformation of a 4-DoF parallel manipulator with three asymmetrical legs are studied systematically for supporting helicopter rotor.
First, a 4-DoF 2SPS + RRPR type parallel manipulator with two linear SPS type legs and one RRPR type composite leg is constructed and its constraint characteristics are analyzed.
Second, the formulas for solving the elastic deformation and the stiffness matrix of the above mentioned three asymmetrical legs are derived.
Third, the formulas for solving the total stiffness matrix and the elastic deformation of this manipulator are derived and analyzed.
Finally, its finite element model is constructed and its elastic deformations are solved using both the derived theoretical formulas and the finite element model.
The theoretical solutions of the elastic deformations are verified by that of the finite element model.
