摘要：
A simplified model of a slider-crank mechanism with a cracked rod is obtained through Lagrange's theory and used to investigate perturbations on the system's dynamic response caused by the presence of an open and non-propagating crack. The open crack is modelled as a massless spring. To further evaluate the influence of crack presence, crack depth and position, torque and pressure forces, the dynamic response of the damaged mechanism is compared to the health system. Results show, for all cases, a significant difference in the kinematic and dynamic response of both healthy and damaged systems.
