摘　　要：馈能是提升坦克装甲车辆悬挂减振性能与减少能量消耗、提高续航能力的有效方案之一,根据机-电-液馈能悬挂系统的工作原理,根据工作原理建立悬挂系统数学模型并搭建流、固、热、磁多场耦合分析模型,分析不同参数对悬挂系统阻尼特性和馈能特性的影响;分析结果表明:机-电-液馈能悬挂系统在正弦激励下具有良好的阻尼特性;旋转液压执行器排量、液压变速/泵/马达排量和少齿差行星齿轮传动比对系统阻尼特性有较大影响,对系统馈能特性影响不大,在不同参数下可达到较高能量回收功率;液压泵/马达容积效率是影响系统馈能特性的关键参数,系统能量回收效率随液压泵/马达容积效率的降低而显著下降,提高液压泵/马达容积效率是保证该系统高能量回收的关键。Energy regeneration is one of the effective solutions to solve the contradiction between the improvement of tank and armored vehicle suspension damping performance,large energy consumption and limited endurance.The working principle of the mechanical-electro-hydraulic regenerative suspension system was introduced.According to the working principle,we established the mathematical model of the suspension system and built the fluid-solid-thermal-magnetic multi-field coupling analysis model to analyze the influence of different parameters on the damping and regenerative characteristics of the suspension system.The results show that the mechanical-electro-hydraulic regenerative suspension system has good damping characteristics under sinusoidal excitation;The displacement of rotary hydraulic actuator,the displacement of hydraulic variable speed/pump/motor and the ratio of planetary gear with small tooth difference have great influence on the maximum damping force,but have little influence on the regenerative characteristics of the system,and can reach high level regenerative power under different parameters.The volumetric efficiency of the hydraulic pump/motor is the key parameter affecting on the regenerative characteristics of the suspension system.The regenerative efficiency of the system decreases significantly with the decrease of the volumetric efficiency of the hydraulic pump/motor.Improving the volumetric efficiency of hydraulic pump/motor is the key to ensure the efficient energy recovery of the system.
