摘要:
为了使悬架减振器在改善汽车行驶平顺性的同时完成振动能量的回收,首先以某品牌减振器为原型设计一种实用新型液压式馈能减振器的原理及结构,依据工作原理构建该减振器的油液流动中流量与压降之间的关系理论模型;然后在AMESim中建立等效参数化仿真模型分析所设计的液压式馈能减振器的外特性及能量回收特性能否满足实际工作需求;最后在Simulink中进行液压式馈能悬架总成AMESim模型与路面时域输入模型的联合仿真,分析此减振器装车后在实际路面激励下对车辆平顺性的影响及能量回收效果.分析结果表明:此液压式馈能减振器压缩/复原行程阻尼力符合减振器阻尼力允差的国标要求;示功图形状饱满无明显畸变,体现出良好的外特性,满足减振器的设计要求;馈能特性符合最初设计的只在压缩行程回收能量的思想;馈能特性曲线呈现出显著的峰值特性并受到减振器高频响应特性的影响;悬架平顺性满足行驶要求,实际行驶中具有一定的能量回收潜力.本文所设计的液压式馈能减振器基本能达到预期目标,对节能减排有借鉴价值.

Abstract:
Firstly, the principle and structure of hydraulic energy regenerative damper is designed based on a brand rear damper in order to reduce energy consumption and realize energy recovery of suspension vibration. Based on the working principle, the theoretical model of the relation between flow rate and pressure drop of the hydraulic energy regenerative damper is established. Then, an equivalent parameterized simulation model is established in AMESim to analyze whether the external characteristics and energy recovery characteristics of the designed damper can meet actual requirements. Finally, the simulation model of the energy regenerative suspension is established and combined with the pavement time-domain input model built in Simulink in order to analyze the influence of the energy regenerative damper on the vehicle ride comfort and the energy recovery effect under actual road conditions. The results indicate that: the compression/extension damping force of the damper meets the national standard requirements; the performance characteristic curve is full without obvious distortion and presents good external characteristics; hydraulic energy regenerative damper meets the original idea of energy recovery only during compression strokes. The results also indicate that: the energy regenerative characteristic curve is affected by the high-frequency response characteristics and presents a significant peak performance; the suspension ride comfort meets the requirement and has certain energy recovery potential in actual driving. The hydraulic energy regenerative damper designed in this paper can meet the expected target, which has reference value for energy conservation and emission reduction.
