Simulation of Vehicle’s Inertia Using a Flywheel Mass to Test Disc Brake System

Abstract

© Springer Nature Switzerland AG 2020. The characteristic of all bodies having a certain mass is that during its movement, in addition to all forces acting, the force of inertia also acts. In the case of the translational motion of the body, such as the movement of a vehicle along a straight line, the force of inertia acts. However, in the case of body rotation, the term moment of inertia is introduced. In order to simulate the inertia of a quarter of a moving vehicle moving, but in a laboratory test, this paper presents a methodology for simulating the inertia of a vehicle using a flywheel mass, i.e. a moment of inertia. In this particular case, an analysis of the required rotational speed of the flywheel was performed in order to simulate a specific speed of vehicle and to test the working characteristics of the disc brakes. Knowing the speed of the translational moving of a quarter of the vehicle model and knowing the characteristics of the flywheel mass, and applying the basics of kinetic energy of these two types of motion, a solution was reached about the required rotation speed of the flywheel mass in order to simulate the movement of the vehicle. The conclusion about the rotation speed of the flywheel mass in order to simulate the movement of the vehicle was reached by deriving the equations from kinetic energy.
