Abstract

In this study the vibration characteristics and dynamical behavior of a general planar mechanism with a flexible link that contain cracks and a revolute joint with clearance at the slider is analyzed. The link flexibility is modelled using the finite element method, and the local flexibilities representing cracks are mod-elled using massless rotational springs. The equations of motion are developed for the non impacting case. The equations of motion in integrated form (called the impact equations) are used to model impact at the joint. The influence of the angu-lar velocity, number of cracks, and clearance of the slider revolute joint on the flexural response of the flexible rod is investigated.
