摘　　要：良好的水冷却系统对电涡流测功机的稳定、可靠运行具有重要的作用.本文针对发动机测功实验台中的GW100B型电涡流测功机,介绍了电涡流测功机的结构,阐述了电涡流测功机水冷却系统的的原理及组成,根据其功能需求,运用热力学理论,设计了一套电涡流测功机水冷却系统,主要包括储水箱、水泵;基于Matlab/Simulink软件搭建了电涡流测功机水冷却系统的模型,仿真了不同冷却温差和工作时间下需要的冷却水体积,结果验证了设计的合理性,满足了电涡流测功机的运行要求.A good water-cooling system plays an important role in the stable and reliable operations of the eddy current dynamometer.This article introduces the structure of the GW100B eddy current dynamometer in the engine dynamometer test bench,explains the principles and makeup of the water-cooling system of the eddy current dynamometer,and designs a water-cooling system consisting mainly of a water tank and a water pump for the eddy current dynamometer based on its functional requirements under the guidance of thermodynamic principles.With the Matlab/Simulink software,a model of the water-cooling system of the eddy current dynamometer is built.The required cooling water volume under different cooling temperature differences and working hours is simulated.The results verify the rationality of the design and prove that the design meets the operating requirements of the eddy current dynamometer.
