Kinematics of RSSH Analysis Research Based on Chebyshev Approximation

The kinematics analysis of RSSH mechanisms is made in this paper.First,a kinematics analysis model is established,elimination of intermediate variables with vector operation is obtained by motion analysis equation.A polynomial equation is obtained from Transcendental equation in the sine and cosine function through the Chebyshev method.The method,without any roots,is a new viable solution to modeling and the Vice-H of spatial mechanism.
