摘要
A new parallel mechanism 3-CCC which has distance and angle constraints is described in this paper. A closed-form solution to the forward displacement analysis of it is presented. Sylvester resultant is used with the angle equations and three distance equations are treated with by replacing the variables, from which 64 different locations of the platform can be derived, numerical example confirms these theoretical results. Velocity and acceleration equations and Jacobean matrix are obtained by taking the derivative of the constraint equations.
