Slider Crank Mechanism with Joint Clearance

Application ID: 89951


Joints between two components of a mechanical system are sometimes not perfectly fitting. For the ease of assembly and to allow relative movement between the components, a small gap called clearance is provided between the joining components. The presence of clearance on joints can sometimes adversely affect the performance of the system by generating impact forces thus giving rise to noise and vibrations.

This model compares the performance of a slider crank mechanism with and without a joint clearance. All components of the mechanism are assumed rigid. Hinge Joint node is used when there is no clearance on a joint whereas Clearance Joint node is used to include clearance on a joint. A transient analysis is performed to analyze the effect of joint clearance on slider velocity, slider acceleration, and crank moment. In addition to this, the dynamics of journal within the bearing and the reaction force in the clearance joint are also analyzed.
