Kineto-static Analysis of a Spatial Closed-loop Mechanism Composed of Elastic Thin Strips

摘要

This paper describes a kineto-static analysis of a spatial closed-loop link mechanism which is composed of elastic thin strips. The relation between elastic deformations and forces and moments at both ends of a rectangular thin strip was defined as a finite element model of a cantilever beam. A system of nonlinear equations with 32 variables to solve elastic deformations and output angular displacement of a four-bar elastic link mechanism was then derived. A simulation was carried out with optimization to solve the system of nonlinear equations.
