DESIGN CALCULATION OF INERTIAL CHARACTERISTICS OF A VEHICLE WHEEL
Abstract
When designing motor vehicles, including heavy-duty special-purpose vehicles, performance characteristics such as traction dynamics and braking performance are evaluated. Modeling the process of acceleration and deceleration is reduced to the differential equation of motion, in order to solve which one should know the moment of inertia of the wheel relatively to its axis of rotation. It is known that the moment of inertia of a solid relative to a given axis is equal to the sum of the products of the masses of all its points by the squares of the distances to this axis. Therefore, previously there is a need to determine the mass of the wheel. However, the experimental determination of the mass characteristics of the wheels at the design stage is not always easy to realize. In this article a method of estimation calculation of the moment of inertia of an automobile wheel relatively to its axis of rotation is proposed. The wheel is represented as a summation of rim, tire and tire tube. In order to determine the inertial characteristics each of those elements is divided into bodies of a simpler form. In addition, the inertial characteristics of the air in the tire tube compressed to a nominal pressure were taken into account. In order to assess the adequacy of parameters calculated by the developed model, the thickness of the listed elements was experimentally established.
