【摘要】 通过求解流体流动时载流振动管弯曲振动方程,得到流体质点所受外力的动态方程。分析振动管弯曲振动能耗与流体质点受外力做功的关系,推导出流动流体在振动管做弯曲振动时的损失能耗量、流体流速和流体动力粘度的关系,从中分析流动状态下流速对粘度测量的影响,并通过实验验证了所得结论。更多还原

【Abstract】 By solving the incurvate vibrating equation,it is obtained the solution of the dynamic equation with flowing liquid inside the tube.The main forces on the liquid particle and the relationship between the loss energy and the power caused by exterior forces are analyzed,and the formula to solve the relationship among loss energy,flow velocity and viscosity are derived.Also the effect of the velocity on the measurement of fluid viscosity is analyzed,and the correctness of the conclusion is proved by experiment.更多还原
