Application of Theory about Movable Axes to Systems of Rigid Bodies with Hinge Joints 动轴理论在铰链连接的刚体系统中的应用
Through disassembling the mechanism at the spherical joints and using the force or moment equilibrium relations of both upper links of the sub-chains and the combinative chain of movable platform and sub-chain upper links, the authors determine the constraint forces acting on the spherical joints. 通过在球铰处将机构拆开,并利用支链上部杆件及动平台与支链上部杆件组合运动链的力和力矩平衡关系确定了球铰处的约束力。
