Stress observation of shaft lining wall during construction and initial operation

Wen Dehua

Strategic Study of CAE 2012, Volume 14, Issue 2,   Pages 80-84

Abstract:

For searching the stress and deformation law of blended shaft-lining during construction and initial operation, sensors were buried in interior and exterior wall of shaft-lining, and automated monitoring system was created. The stress and deformation law was obtained by analyzing the test results. With the law, we can forecast the long-term safety of shaft lining and provide scientific decision evidence for preventive and treating measures of broken wall.

Design and characteristics of electric supercharger for diesel engine acceleration by additional rapid

YAO Chun-de, ZHOU Hong-xiu

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 4,   Pages 409-412 doi: 10.1007/s11465-006-0048-5

Abstract: The ES (electric supercharger) driven by a high-speed brushless motor was developed to solve the problem of smoke caused by the turbocharger s sluggish response during acceleration. Its rotation speed was from 6 000 r/min to 24 000 r/min, and the maximum flux was 0.1 kg/s. The structural design of the electric supercharger is novel, which makes it easier to set the lubricating installation and to assemble. The velocity distribution at the outlet of the electric supercharger is determined by hot-wire anemometry under various rotation speeds in steady state. Furthermore, the trends of the flux and charge rate with various speeds were analyzed. In addition, the transient response was detected from the motor setup to smooth running within 10 s, 15 s, 20 s and 25 s respectively, and the characteristic of the transient flux is under pilot study. Research results indicate that the electric supercharger can respond rapidly with the great flux, and it is independent of the operating conditions of a diesel engine. Therefore, it is a feasible way to reduce smoke emission and improve the acceleration performance.
