Generation mechanism and control of high‐frequency vibration for tracked vehicles

Abstract A crawler system provides much larger ground contact, leading to excellent terrain adaptability. Due its structural characteristics, high‐frequency vibration proportional the vehicle speed is generated during driving process. This a result of polygon and rolling effects between track wheels. field test tracked performed monitor movement signals chassis rocker arm. Their corresponding power spectral density distributions confirm correctness frequency‐calculation equation. Then, novel elastic tensioning device with damper designed as cushion idler chassis. Depending on geometry, equivalent damping coefficient for dynamic model evaluated. Subsequently, altered in response different operating conditions by hybrid fuzzy semiactive control system. The controller accounts both vibration. Based transfer matrix method multibody systems, dynamical developed. Control performances are evaluated using two numerical simulations obstacle crossing off‐road operations. Results indicate that proposed tensioner substantially better than conventional one. paper feasible scheme reduction vehicles.
