Simplified Modeling of Quarter and Half Car Suspension Systems Using Electrical Circuit Analogies

In this paper, half-car and quarter-car suspension systems are modeled using an electrical circuit analogy based on the force-tension relationship, with a focus on inductive coupling, which mirrors the mechanical coupling due to the vehicle’s pitching effect. The validation is performed by comparing results from electrical circuit simulations with those from traditional mechanical modeling. MATLAB simulations generate transmissibility ratio curves for both methods, which are then compared. The study shows a strong correlation between mechanical and inductive coupling, demonstrating the effectiveness of electrical analogies for simulating vehicle dynamics.
