基于锥阀控制的惯容切换悬架阻尼力跟随方法
Damping Force Following Method Based on Poppet Valve Control for a Switching-type Inerter-based Suspension
摘要
Abstract
To address the difficulty in achieving consistent damping force before and after the large-and-small inerter switching of a switching-type inerter-based suspension under high-impact driving conditions,a technical scheme featuring a poppet valve in parallel with a long straight hose is proposed.By adjusting the throttling area of the poppet valve,its damping force is made to follow in real-time in the long straight hose.Through analysis of the pressure differential-flow rate characteristics for both the poppet valve and the long straight hose,the required real-time valving element displacement of the poppet valve for achieving consistent damping force between the poppet valve flow path and the long straight hose flow path is obtained.A following strategy for the poppet valve to follow the damping force of the long straight hose is constructed,and its key parameters are optimized.Simulations are conducted using AMESim for both sinusoidal high-impact conditions and actual high-impact driving conditions.The suspension's velocity-damping force characteristic curves are obtained under the sinusoidal high-impact condition,and the suspension's damping force versus time curves are obtained under the actual high-impact driving condition.Experimental validation under the sinusoidal high-impact condition is conducted.The results indicate that the damping force error between the poppet valve flow path and the long straight hose flow path is reduced from 29.36%(with a fixed orifice)to 5.85%under the sinusoidal high-impact condition,and from 16.15%to 2.22%under the actual high-impact driving condition.关键词
