    隨著鐵路運輸速度的提高，車輛的輕量化顯得越來越重要，減輕車輛自重，不僅可以減少原材料的消耗，有利於降低牽引功率，提高列車的運行速度，改善列車的啟動和制動性能，而且可以有效的減少輪軌間的動力作用，減少振動和噪音，增加車輛和線路的使用壽命，節約運輸成本。
  2. This new technology changes from the traditional method by which the induced and compressor wheel separately are designed and produced to a new one by which the one - piece compressor is designed. on the basis of this new technology and the optimum blade profile, the performance of both the compressor and the turbocharger is largely improved. through the heating power calculation of the compressor, the analysis of the surge and the block of the compressor, the test - bed performance test of the turbocharger, the matching test of turbocharger and diesel engine, the propulsion test of the turbocharger on plateau condition, it is proved that the newly - designed compressor not only has high efficiency, but also improves the flow distribution in the high efficiency area so that the propulsion line can run through the high efficiency area

    主要內容包括：提出一種全新的壓氣機葉輪技術和概念，這種技術將傳統的導風輪和壓氣機分開設計、單獨加工改為整體設計、整體加工的單體葉輪；從增壓器與柴油機配機計算所得出的基本參數出發，通過對壓氣機進行熱力計算，確定壓氣機的基本結構參數；再對葉型以及葉輪輪廓與葉輪罩殼的配合間隙進行優化，對新設計的壓氣機進行喘振和堵塞分析；通過增壓器平臺性能試驗，驗證了新設計的壓氣機的性能水平得到了較大的提高，達到了提高增壓器的整體性能水平的目的；通過增壓器與柴油機配機試驗、以及增壓器用於高原條件下的牽引試驗，驗證了新設計的壓氣機不但具有高效率，還改善了高效率區的流量分佈，使牽引特性線貫穿高效率區。
