| Abstract: | Dynamical response of four bar linkage with a clearance is investigated. By employing Dubowsky's model for clearance and Lagrange equation, the equations of motion of this mechanism are developed. Numerical method is used to solve the problem. By applying Poincare map and bifurcation diagram, phenomena of chaos and bifurcation are discovered and the routine to chaos through period doubling is illustrated. The results of this paper suggest that the variation of magnitude of clearance leads to the transform between chaos and harmonic response and the period doubling is one of the routes from period response to chaotic response. |
