Comparing with the system of r22 at the same working condition , it is indicated that heating capacity and work consumption of the system of ( 30 / 70wt % ) r32 / r134a are inferior to that of the former , but its heating cop is higher than the former at the lower temperature condition 并对相同工况下,两种工质的系统进行了性能比较。结果表明:与纯质r22系统相比,采用混合工质( 30 70wt ) r32 r134a的系统吸热量和制热量要低,耗功量要小,制热系数在低温工况下要高。
In this paper , the mathematics model and simulation model of the passive landing gear shock absorber was built , and was verified by drop test . aimed at acquiring suitable efficiency diagrams , two simple semi - active control algorithms were designed . the mathematics model and simulation model of the semi - active landing gear shock absorber was built 在本文中,建立了被动控制起落架缓冲系统数学模型和仿真模型,并通过落震试验对该模型进行参数校验;以合适的功量图为控制目标设计出两种半主动简单控制律,建立了半主动控制起落架缓冲器数学模型和仿真模型;通过数字仿真对这两种控制方法进行了比较,认为半主动控制较被动控制有很大的优越性。
