Electrical characteristics of a typical vehicle horn are determined by its resistance and inductance. The inductance is affected by factors such as the magnetic circuit, current magnitude, eddy currents and material properties. The mechanical characteristics of the vehicle horn are also affected by its material properties, the horn structure and its natural frequency. Mechanical and electrical parameters change during the operation of a
vehicle horn. Therefore, it is difficult to predict the vehicle horn performance and hence, its design. In this study, firstly, the electrical and mechanical system of a vehicle horn are mathematically modeled. Secondly, the
electrical and mechanical parameters are calculated using the finite element analysis method. Thirdly, to predict the operating characteristics of the vehicle horn, the electrical/mechanical system equations are solved by
applying the parameters obtained from the finite element analysis. Finally, the simulation results and experimental results are compared and verified.
