用模拟修正法对动力转向器性能计算的研究

Amendment Act of Analog Performance Calculation of Power Steering

用计算机模拟在实际试验中所取得的性能曲线，然后与理论计算曲线作比较，取二者的差值，此差值即可作为改进计算的修正量。修正后的计算就不只是一种几何计算，因为修正量是流体的附面层厚度，因此修正后的计算使原来的几何间隙变成为液流间隙．因此这样计算的结果就比较准确，这种方法计算的结果与国外对转阀进行了大量的流量试验所得到的结果基本一致。

Computer simulation in the real test of the performance curve obtained, and then compared with the theoretical curves, take the difference between the two. This difference can be calculated as an amendment to the amount of improvement. The revised calculation is not only a geometrical calculation ,because the amendment that is the amount of the fluid boundary layer thickness, so the calculation will be revised so that the original geometric space into a space for the flow. Therefore, the results of this calculation is more true and accurate. The results calculated in this way turn valve with the United States carried out a lot of traffic tests the results obtained basically the same.
