Equipment and Methodology for Detecting Clearance in Front Suspension Joints of Passenger Vehicles by Using Dynamic Acceleration

This paper introduces an innovative system designed to detect the existence of clearance in the joints of front suspension and steering systems of passenger vehicles. The system employs dynamic acceleration analysis by tilting the motor vehicle chassis using a pneumatic actuator and utilizes accelerometers to detect the existence of clearance at various points in the suspension and steering components. The research showcases the development and application of the system, supported by advanced data acquisition (DAQ) technology and a comprehensive methodology. Experimental data is collected in realtime and processed using LabViewsoftware, with results visualized through acceleration, velocity, and position graphs. Furthermore, a Bode plot provides insight into the behavior of accelerations at different frequencies, aiding in the objective assessment of the front suspension joints' condition. The outcomes of the study provide valuable insights into enhancing motor vehicle maintenance and improving the performance of suspension and steering systems. Further investigations could delve into additional factors influencing joint wear and refine the analysis methodology.
