Distribution of the residual tolerable imbalance between correction plans

Abstract

Shimmy is a self-accident lateral and yaw vibration of a wheel caused by the interaction between the dynamic behavior of the tire and the supporting structure. The shimmy affects road vehicles, motorcycles, and aircraft landing gears. This undesired vibration can increase to a considerable amplitude, producing loss of control and may even result in severe damage to the wheel-suspension system. Suitable tools and models are required to assess the system’s stability properties and understand shimmy mechanisms. This research focuses on the technical solutions to reduce the shimmy phenomenon. The suspension, axle, and bearing part on the axle work together in a united way to protect against the forces transmitted by the wheels’ imbalances. This physical phenomenon suggests balancing the wheel by considering a mechanical system consisting of suspensions, axles, and wheels. In the design phase, the research suggests balancing the axle and wheels, comparing two planes, and influencing coefficient methods. An inertial measurement unit (IMU) sensor can capture mechanical vibrations on the wheel at various vehicle speeds.
