Experimental validation of two wheeler damper using with MATLAB

For the implementation of a parametric model of an automotive damper this research was to create a damper model to predict accurately damping forces to be used as a design tool for the damper design team. The model accounts for each individual flow path in the damper, and employs a flow resistance model for each flow path. The deflection of the shim stack was calculated from a force balance and linked to the flow resistance. These equations yield a system of nonlinear equations that was solved using Newton’s iterative method. this model was to generate accurately force vs. velocity and force vs. displacement plots for examination. The dynamic model and analysis is used to correlate the model to real damper data for verification of accuracy. With a working model, components including the bleed orifice, piston orifice, and compression and rebound shims which were varied to gain an understanding of effects on the damping force.
