Abstract
In motion generation, the objective is to calculate the mechanism parameters required to achieve or approximate a set of prescribed rigid-body positions. This doctoral dissertation study is aimed to integrate the classical kinematic analysis of a planar four-bar and geared five-bar motion generation with three structural design constraints. These constraints consider driving link static torque, deflection of the crank and buckling of the follower for a given rigid-body load or constant external load.
This kineto-elastostatic analysis is based on the following assumptions to be considered during the analysis; the crank and the follower are elastic members and the coupler is rigid member, friction in the joints is neglected, link weights are neglected compared to a given rigid-body load or constant external load, the cross sectional properties of a link do not vary, and finally the mechanism is moving in quasi static condition.
By incorporating these constraints into conventional planar four-bar and five-bar motion generation models, mechanisms are synthesized to achieve-not only prescribed rigid-body positions-but also satisfy the above mentioned structural constraints for a given rigid-body load or constant external load.
