平稳性指标W和加权加速度A_w不能相互换算的分析

Analyzing the Fact that the Stability Index W Could not Be Converted Into the Weighted Acceleration Index A_w and Vice Versa

对TB/T2360—93《铁道机车动力学性能试验鉴定方法及评定标准》附录C3中平稳性指标W和加权加速度Aw的换算公式进行了分析,从平稳性指标W和加权加速度有效值Aw定义分析了二者的关系,结果表明平稳性指标W和加权加速度Aw不能相互换算,W和Aw没有相关性,需分别通过计算获得。

The author analyzes the formula for conversion between stability index W and weighted acceleration index Aw which is included in the appendix C3 of standard TB/T 2360-93 ＂Identification Method and Evaluation Criteria for Dynamics Performance Experiment of Rail Locomotive＂, and analyzes the relationship index W and the effective value Aw from the viewpoint of their definitions. The analysis result shows that stability index W and the weighted acceleration index Aw could not be converted mutually. There is no regression between W and Aw, the two indexes could only be gained through respective calculations.
