【摘要】 在建立电力机车受电弓滑动产生的无线电噪声脉冲幅度概率（ＩＡＰ）分布数学模型的基础上，计算出不同车速时的脉冲幅度分布曲线，通过求出平均脉冲速率，利用干扰测量仪的相对脉冲响应曲线得出以１６０ｋｍ／ｈ和２４０ｋｍ／ｈ速度行驶的“动力集中型”电牵引列车产生的无线电噪声电平分别比以８０ｋｍ／ｈ运行时的噪声电平高出６ｄＢ和８ｄＢ。更多还原

【Abstract】 The paper presents a model for radio noise impulsive amplitude probability (IAP) from electrified railways. Based on the model,impulsive amplitude distribution curve for different train speeds are calculated. With averaged impulse rate calculated from IAP,the radio noise levels for different train speed are obtained from relative impulsive response curve. The radio noise level of a train at 160 km/h or at 240 km/h is 6 dB or 8 dB higher than that of a train at 80 km/h.更多还原
