| 摘 要： | 激光除冰技术是一种非接触式除去电气设备覆冰的新技术。为了考察激光对冰块的作用情况,并为选取激光除冰的最佳参数提供理论依据,该文结合实际激光除冰情况,利用有限元分析软件建立了激光与冰块的作用模型,对冰块中瞬态温度场与应力场进行了仿真,得到了温度场与应力场分布的变化过程图、不同初始温度冰块的融穿时间曲线以及不同激光功率、不同光束直径时冰块融穿时间变化曲线。通过仿真分析,给出了激光除冰设备参数选择的具体要求,对实际除冰具有重要指导意义。

| Abstract: | Laser de-icing is a new non-contact method for electrical system component deicing.A finite element model of laser de-icing was used to analyze the effect of laser de-icing and ascertain the theoretical basis for choosing the best laser de-icing parameters.The model simulates the temperature and stress fields in the ice during the laser de-icing process.The temperature and stress fields and the penetration rates are given for different initial temperatures,laser powers and beam widths.Specific requirements ... |
