The Mechanical Characteristics Study on an Interconnected Anti-Rolling Suspension System

Abstract

The heavy-duty special vehicles easily roll during steering, anti-rolling technology becomes a critical technology to the heavy-duty vehicles. Aiming at the rolling problem of a full load heavy vehicle in the process of steering, an interconnected anti-rolling suspension system with adjustable damping was designed, the nonlinear mathematical models of both hydro-pneumatic independent suspension and interconnected anti-rolling suspension system were established. The mechanical characteristics of two kind of suspension were studied through digital simulation method, discussing the system parameter changes affection on the performance of interconnected anti-rolling suspension system. The study results indicate that the interconnected anti-rolling suspension system bitterly improves vehicles rolling resistance in contrast to the oil-gas mixed independent suspension, the study results provide theoretical basis for the anti-rolling s design of heavy-duty vehicles.
