摘　　要：针对用于多电飞机的机电作动器,通过实验研究的方法,明确机电作动器在不同工况下的产热特性,并测定各工况温度以获得机电作动器的热量传输特性。结果表明:机电作动器的主要热源为永磁电机,"高作动速度、大出力"的工况是机电作动器面临的最恶劣工况,仅凭自然对流换热无法将热量有效散出。通过实验阐明了机电作动器在典型工况下的产热与传热规律,为机电作动器散热方法与技术的研究指明方向。To ensure the heat dissipation and heat transfer characteristics of the electromechanical actuator used in more electric aircraft,temperature and heat dissipation coefficients of the actuator are measured.The results show that the main heat source is the motor winding,the working condition of“high velocity and load force”,and the actuator could not be cooled effectively only with natural-convection heat transfer.The heat dissipation and heat transfer characteristics of the electromechanical actuator are stated through experimental study.The direction is showed clearly for the study of its cooling method and technology.
