发动机动态试验台的混合模拟研究

为进行发动机和整车的测试、研究和开发提供一种经济而高效的手段，本文在借鉴他人发动机动态试验台的基础上，采用混合模拟的方法，利用中国生产的电涡流测功器自行开发发动机动态试验台。具体介绍了发动机动态试验台混合模拟的方案，论述了该试验台的控制原理，对试验台的控制进行了仿真。结果表明混合模拟的方法是自行开发发动机动态试验台的行之有效的方法。

Study on the hybrid simulation of engine dynamic test bed

To provide an economic and efficient method for testing, studying and developing a new engine and vehicle, the hybrid simulation method was adopted to develop engine dynamic test bed based on domestic eddy current dynamometer and by reference to the foreign advanced engine dynamic test bed. The hybrid simulation scheme of engine dynamic test bed was introduced. The control principle was discussed, and the control simulation was carried out. The results show that the hybrid simulation method is an efficient way to develop engine dynamic test bed.
