the slider-crank mechanism by using MSC Adams/View software. Using the Lagrangian approach, a dynamic model was established by considering the effect of faults induced by heavy clearance. Furthermore, three-dimensional simulation of the model was verified. The study reveals that the gaps existing between the joints of the mechanism have a considerable impact on the response of mechanisms, hence increasing vibration, shock, and shifts in critical system parameters including but not limited to displacement, speed, and acceleration. The impacts are magnified with higher levels of clearance.
Adams provides a robust solution engine to solve your mechanical system model. The software checks your model and automatically formulates and solves the equations of motion for kinematic, static, quasi-static, or dynamic simulations. With Adams, you don’t have to wait until the computations are complete to begin seeing the results of your simulation. You can view animations and plots – and continue to refine your design – even as your simulation is running, saving valuable time. For design optimization, you can define your variables, constraints, and design objectives, then have Adams iterate automatically to the design, providing optimal system performance.

1.2 Introduction to Slider Crank Mechanism
1. INTRODUCTION FOR MSC SOFTWARE
The slider-crank mechanism is a typical reciprocating mechanical system which consists of revolute and translational joints. In practice, motion clearance is inevitable mainly for three reasons: 1 First of all, the assembly clearance (normal clearance) is designed for rotation and sliding hinge movement. Second, fit and finish errors are designed into the joint components when they are manufactured. The third source of irregular clearance is due to wear and tear of the motion pair itself. Whether it is, a natural phenomenon, a design flaw or an assembly defect, the existence of clearance adversely affects dynamic behavior, especially rub-impact for the slider-crank mechanism. In recent years, a limited.

2. LITERATURE REVIEW Flores et al. [2] introduced a general approach for modeling and analyzing multi-body dynamics in revolute joints with multiple clearances. In their study, they developed a continuous contact force model, based on elastic Hertz theory and dissipative terms, considering the actual joints as collision bodies affected by geometric and physical properties. Their findings emphasized that both the clearance size and operating conditions are critical for accurately predicting the system's dynamic response.
