This paper presents the design and fabrication of a damper test rig developed to determine the characteristics of shock absorbers employed in passenger car suspension systems. The test rig is designed explicitly for automotive suspension systems and provides vertical excitation to the shock absorber arm. It is equipped to collect force and displacement signals from the arm, enabling a comprehensive analysis of damping characteristics. The system supports experimenting with various dampers, including magnetorheological dampers, under controlled experimental conditions. The test platform features a rigid frame structure and a data acquisition system connected to a computer, allowing precise measurement of force-displacement characteristics and force-velocity dynamics. Experiments conducted using the test rig demonstrate its reliability and accuracy in evaluating damper performance. This system is essential for researchers and engineers seeking to optimize suspension designs, improve vehicle ride comfort, and enhance handling.
