摘　　要：在风力发电机齿轮箱故障诊断中信号采集是故障分析诊断的前提条件,同时也是必要条件,目前最为成熟的方法为振动信号分析方法,而由于齿轮箱内部结构不能破坏等原因导致振动传感器只能安装在齿轮箱外壁,齿轮箱外壁传感器位置布置的优劣会直接影响诊断精度;为此,采用免疫算法解决风机故障诊断中传感器测点布置的问题,构建齿轮箱振源坐标系,计算振动传输的最佳采集路径,确定最佳测点,实现了传感器测点的优化布置,为传感器布置提供了有效的方法。The signal acquisition is a prerequisite for fault analysis and diagnosis, but also the necessary condition in the fault diagnosis of wind turbine gearbox. At present, the most mature method is vibration signal analysis method, however, because the internal structure of the gearbox can not be destroyed, it can only lead to vibration sensor installed on the external wall of the gearbox. The sensors arrangement of gearbox will directly influence the quality of diagnostic accuracy. By using the immune algorithm to solve the problem of sensor arrangement in fault diagnosis of wind turbine, the gearbox vibration source coordinates is constructed, the optimal acquisition path of vibration transmission is calculated, the best measuring point is determined. The placement optimization of the measuring point for sensor is realized, an effective method for sensor arrangement is provided.
