中文摘要:
      为降低液力缓速器空转损耗,以自主开发的THB40液力缓速器样机为基础,在不影响制动效果前提条件下,研究空转损耗流场沿叶片弦面的速度涡特性矢量云图,依据油液与空气产生的冲量不同,设计出一种仅对空转涡流场有效降损的扰涡技术方案;使用数值计算方法对扰涡技术方案降损效果进行16个速度点的预测分析,结果表明:最小降损率为7382%,最高降损率为7827%,平均降损率为756%。研究内容为液力缓速器降空损设计提供技术思路与计算方法。
英文摘要:
      In order to reduce the idling loss of hydraulic retarder, based on the self-developed THB40 hydraulic retarder prototype, the velocity vortex characteristic vector nephogram of the idling-loss flow field along the blade chord surface was studied without affecting the braking effect. According to the different impulse between oil and air, a kind of anti-vortex technology program was designed to reduce the loss of idling vortex field. The prediction and analysis was conducted on the anti-vortex technology program by using the numerical calculation method with 16 velocities.The results show that the minimum loss reduction rate is 73.82%, the maximum loss reduction rate is 78.27%, and the average loss reduction rate is 75.6%. This research provides technical ideas and calculation methods for the design of hydraulic retarder.
