新型汽车转向叶片泵建模和仿真

为了降低汽车液压动力转向系统中存在的较大能量损失，整个转向系统要消耗原动机约3％的能源，但真正转向消耗的能量只占其中不到40％的问题，提出了一种含有浮动块的新型汽车转向泵。同时研究新型转向叶片泵变量机构的动力学特性，分别建立了变量机构的动力学和叶片泵流量模型，并对泵在液压转向系统向系统执行机构的输出流量进行仿真. 结果表明该泵能有效降低转向系统的能量损失，是一种较有应用前景的新型叶片式转向泵.

Formation and simulation on the new steering vane pump

To take account of the fact for an automotive hydraulic power steering system have serious energy loss: the entire system will cost 3 percent energy of the engine, but only 40 percent of it will transfer to consumed energy, while the other 60 percent of the energy will be wasted., this paper discusses the configuration and the action principle of a new energy saving steering vane pump, which consists of a floating block. In addition the dynamics formulation of the variable mechine is studied. The model of variable is developmented and the simulation of flux with the pump is performed. The results show that the pump with the floating block can reduce the energy efficiently and prosperous utilization is expected.
