Review of Research on Vehicle Hydro-Pneumatic Suspension Technology
摘要
Abstract
The hydro-pneumatic suspension has the functions of cushioning and damping,body attitude adjustment,etc.,but its structure is complex,with large pressure impact and high wear resistance and sealing.The excellent suspension cylinder structure,hydro-pneumatic suspension system,and control method are the important conditions to determine the driving performance of the vehicle.The type of hydro-pneumatic suspension was analyzed,and the classification and principle of hydro-pneumatic suspension were summarized from the aspects of suspension structure,working characteristics,and control mode.From the perspective of suspension controllability,the hydro-pneumatic suspension technology was discussed in terms of structural design and optimization of hydro-pneumatic suspension,mathematical modelling,and control algorithm and strategy.By analyzing the characteristics and shortcomings of existing structures,it is concluded that passive suspension is simple in structure and mature in technology,but it lacks adaptability.The semi-active suspension has low energy consumption,low cost,fast response,and high reliability,but its adaptability is limited.Active suspension has excellent performance,but it has high energy consumption,high cost,and complex system structure and control strategy.The development status and research direction of the three types of suspension were summarized and prospected,so as to provide a reference for the further research and development of vehicle hydro-pneumatic suspension design and control methods.关键词
