Balancing of Spatial Systems
摘要
The methodology proposed in Chap. 5 to balance and minimize torques/forces of planar mechanisms is extended in this chapter for the spatial mechanisms. Spatial mechanisms need more exhaustive treatment compared to their planar versions. Both the kinematics and dynamics of the spatial mechanisms are more complex. The dynamic behavior of a mechanism depends on its total mass, mass center location, and the inertia tensor. For spatial mechanisms, a system of point-masses is equimomental to the mechanism, if it satisfies the conditions of the same mass, the same mass center location, and the same inertia tensor.
