摘要
通过对IEC 61373-1999与IEC 61373-2010铁路应用机车车辆设备冲击和振动试验试验标准的比较,主要分析了振动试验中的模拟长寿命试验的量级变化。两种版本振动试验量级变化的原因是标准中采用的S-N模型发生变化,从而导致计算加速度比的方法有所改变。
Through comparison stock equipment Shock and test is mainly analyzed. The acceleration ratio, which is of IEC 61373-1999 and IEC 61373-2010, Railway applications - Rolling vibration tests, the change of vibration level of simulated long-life reason of difference is explained in according to the calculation of the caused by change of S-N modal used in the standard.
