摘要
针对汽车起重机中起重机子系统操作过程中产生的瞬态电磁骚扰,分析了其时域特性,并将主要骚扰源的幅值、频率参数与ISO 7637-2中的标准抗扰度测试波形进行了对比。结果表明:汽车起重机暂态电磁骚扰电压幅值偏低,但存在着严重的高频骚扰,将现有标准应用于汽车起重机的抗扰度测试时应进行相应的调整。
The transientelectrom agnetic disturbancewasmeasured during the operation of the truck crane,and the time-domain characteristics of possible disturbance sources were analyzed.The amplitude and frequency parameters of major disturbance sources were compared with the standard immunity test pulses suggested by ISO 7637-2.The results indicated that the transient disturbance amplitudes of track crane were lower,but severer in higher frequency range.So,corresponding adjustment should be performed when adoptingtheexistingstandardfortheelectromagneticimmunitytestforthetruckcrane.
