摘　　要：被动悬架通过减振器将车辆振动能量转化为热能散发到空气中以达到车辆减振的目的,而馈能式悬架正是要将这一部分能量回收利用,因此减振器耗散能量的估算对预测馈能式悬架的能量回收潜力具有重要意义。通过建立二自由度悬架模型对悬架动位移、动速度以及可回收能量进行了仿真计算,并通过实车道路试验验证了仿真模型及计算方法的正确性,同时对影响可回收能量大小的各个因素进行了分析,明确了轮胎刚度、路面等级、车速是影响可回收能量的关键因素。通过对可回收能量数值的分析得出,馈能式悬架更适合应用在重载车辆之上,并且可回收能量数量十分可观。Passive suspension through a shock absorber converts the vibration energy in vehicles to thermal energy that is then is released into air,in order to reduce the vehicle′s vibration.However,the energy-regenerative suspension can harvest part of this energy.It is thus significant to analyze the dissipated energy in order to estimate the potential of energy-regenerative suspension.In this paper,aquarter car model is built to research the suspension′s dynamical displacement,dynamical velocity and recyclable energy.A road test is carried out to verify the simulation method.Meanwhile,the influence factors related to the potential vibration energy are analyzed,and the results show that the tire stiffness,road grade and vehicle velocity significantly impact the amount of recyclable energy.Throughout the analysis,it can be found that energy-regenerative suspension in the context of recyclable energy is appropriate for commercial vehicles.
