In this paper, the velocity and inertial force 3-RlowbarRlowbar(lowbarRlowbarRmacr)macrRmacr performance of a new parallel mechanism are analyzed by global conditioning index which includes Jacobian matrix and Hessian matrix, and this index is different from the old one which only includes Jacobian matrix. The performance atlas are given, and the(More)
