The structure and operating principle of an air - charged split - type adjustable shock absorber was described , e non - linear parameterized mathematical model of this shock absorber ' s damping characteristics was established according to fluid mechanics theory and the main structural affection factors to shock absorber ' s damping performance , such as the diameter of piston valve orifice , the diameter of adjustable orifice , the initial volume of gas chamber , the diameter of piston rod , the inner diameter of oil pipe and so on , were analyzed by simulations 摘要通過分析一種分體式充氣可調阻尼減振器的結構和工作原理,運用流體力學理論,建立了該減振器阻尼特性的非線性參數化模型,仿真分析了活塞阻尼閥孔徑、阻尼調節孔徑、氣室初始體積、活塞桿直徑、油管內徑等主要結構參數對減振器阻尼性能的影響,通過試驗測試,得到了減振器樣件的阻尼特性及其可調范圍。

3 . comparing two different engines tested on the dynometer : the hirth2706 equips carburetor system and charge as piston valve , and the hirth3203 equips electronic control fuel injection system and charge as reed valve 3 、對采用活塞閥進氣、化油器供油方式的hirth2706發動機與采用簧片閥進氣、電控燃油噴射方式的hirth3203發動機進行性能對比臺架試驗。
