开发了一个测试精度高、测试周期短、试验数据处理快速准确的综合试验台来进行液力变矩器性能试验,完成对液力变矩器静态和动态性能测试;同时,为了提高车辆的动力性能、经济性能,也必须对不同型号变矩器与发动机进行匹配试验。试验台主要由驱动装置、变矩器、变矩器油路供给系统、加载装置、传感器、信号传输系统和信号处理系统等组成。各系统装置的选择方案和设计直接影响试验精度,信号处理手段直接影响测试周期以及试验数据处理的速度和精度。通过对各主要组成部分的分析确定了各部设计方案。提出为了设计出高性能的液力变矩器,必须对内部流动进行测试,以掌握内部流场的结构和分布。在现有的试验台上进行了改造,以满足上述试验的要求。
A comprehensive test stand with high test accuracy, short test period and fast and accurate test data processing is developed to test the performance of hydrodynamic torque converter. The static and dynamic performance tests of the torque converter are completed. At the same time, in order to improve the power of the vehicle Performance, economic performance, but also must match different models of torque converter and engine. The test bench is mainly composed of driving device, torque converter, torque converter oil supply system, loading device, sensor, signal transmission system and signal processing system. The selection scheme and design of each system device directly affect the test accuracy. The signal processing method directly affects the test cycle and the speed and accuracy of the test data processing. Through the analysis of the major components to determine the design of the ministries. It is proposed that in order to design a high performance torque converter, the internal flow must be tested to understand the structure and distribution of the internal flow field. In the existing test bed was modified to meet the above test requirements.
