Reduction Of Inertia-Induced Forces In A General Spatial Mechanism, Sahidur Rahman
Dissertations
A computer-aided design procedure has been developed for minimizing the adverse effects of the inertia-induced forces by optimum mass redistribution amongst the links of high speed general spatial linkages. The evaluation of an optimality criterion for the mass redistribution of the mechanism will be carried out with the aid of a quadratic programming technique. This has been found to be successful in minimizing inertia induced forces and torques. The validity of the optimization procedure will be demonstrated by application to one kind of spatial linkage.
No literature has been found on the balancing of a general spatial mechanism, since its …
Kinematic Synthesis Of Mechanisms For Multiply Separated Positions, Hyoung Jun Kim
Kinematic Synthesis Of Mechanisms For Multiply Separated Positions, Hyoung Jun Kim

The rigid body motion is studied in a combination of finitely and infinitesimally separated positions in planar, spherical, and spatial kinematics. A general new method for determining the locations of points and/or lines in a rigid body moving through finitely and infinitesimally separated positions is developed. These points and/or lines would satisfy the constraints of various types of binary links for planar, spherical, and spatial mechanisms.
A unified form of circle-point curve equation is derived for finitely and multiply separated position problems in planar and spherical motions. A graphical method to construct the circle-point and center-point curves and Ball point …
