rigid body (redirected fromRigid body motion) An idealized extended solid whose size and shape are definitely fixed and remain unaltered when forces are applied. Treatment of the motion of a rigid body in terms of Newton's laws of motion leads to an understanding of certain important aspects of...
attached to judiciously determined locations on a body undergoing displacement, coupled with the appropriate equations of mathematical physics, serves as a normative approach, across multiple application areas, for quantifying and qualifying the kinematic response associated with rigid body modes of motion....
Mechanism is made up of links and kinematic pair joints which move in the three-dimensional space. Many physical objects are considered as rigid bodies for the convenience of theoretical analysis. For rigid body motions, the representations of rigid body
This is because, for planar problems (where motion is in one plane), IG would be independent of the orientation of xyz (relative to the rigid body). For the general case (where we have an arbitrary orientation of xyz within the rigid body), the last three equations describing the motion...
This paper presents a comparative study of the rigid-body inverse dynamics of a spatial redundantly actuated parallel mechanism constrained by two point contact higher kinematic pairs (HKPs). Firstly, its constrained motions are analysed comprehensively,
the finite twist motion of a rigid body, and applies this concept to the problem of describing the motion capabilities of planar serial manipulators. In... JS Dai,N Holland,DR Kerr - 《Proceedings of the Institution of Mechanical Engineers Part C Journal of Mechanical Engineering Science》 被引...
The center of mass of a rigid body is defined. The concept of the moment of inertia is introduced and shown to be intimately related to angular momentum. The equations of motion (translational and rotational) of a rigid body are written. Conservation of angular momentum of a rigid body is ...
