U形渠道直壁式量水槽过渡段曲面的设计

Transition Curve Surface Design of Measuring Flume of U-Shape Canal Straight Wall Type

针对U形渠道过渡段制作精度难以控制,进而影响量水槽的量水精度这一问题,推导了U形渠道直壁式量水槽过渡段曲面的设计方法,为过渡段曲面的准确计算提供了依据。算例结果表明,该方法在量水槽的设计、制模和制作中能保证精度,可供有关技术人员参考。

With an aim at solving the problem of being difficult to control over construction accuracy of U-shape canal transition and further affecting the water measurement of measuring flume,the design method of measuring flume of U-shape canal straight wall type is duduced so as to provide the basis for the accurate computation of transition curve surface. The results of computation examples indicate that this method can guarantee the accuracy in designing,constructing prototypes and making flume as well as provide references for the technical personnel concerned.
