密度变化对调速液力耦合器性能测试影响

The Influence of Density Changing on the Shifting Coupling Liquid Device

在常规的耦合器台架测试过程中 ,油液的密度是按照定值计算的 ,油液在实际流动过程中却是变化的 ,如不考虑油液变化的因素 ,将会使耦合器的测试值不准确。本文对此进行了分析 ,并用试验的方法加以了验证。

In the normal testing of coupling liquid device,the oil density is calculated based on a fixed value,but the oil density during flowing has changed.If we don't take the changes into consideration,the testing will not be accurate.This article discusses the problem and draws a conclution by testing.
