摘要

火炮后坐能量转换装置的工作性能受发电机温升的影响较大,根据火炮后坐能量转换装置的运行特点和结构特点,结合热力学相关方程对该装置运行过程中的发热源进行分析和计算;再根据圆柱体导热模型确定绕组的等效导热系数,并根据片层叠加模型确定铁心的导热系数;通过建立火炮后坐能量转换装置温升计算模型,确定火炮后坐能量转换装置各部位的温升状况;建立火炮后坐能量转换装置的三维温度场模型进行分析并提出了降低温升的措施。结果表明,在常温射击环境下完成单发射击,定子绕组平均温升为1. 05℃,可以满足火炮连续射击条件下的性能要求。
        The performance of the rear-seat energy transfer device is greatly affected by the temperature rise of the generator. According to the operation characteristics and structure characteristics of the recoil energy conversion device,the heating source in the operation of the device was analyzed and calculated according to the thermodynamic equation. Then,the equivalent thermal conductivity coefficient of the windings was determined according to the heat transfer model of the cylinder,and the thermal conductivity of the core was determined according to the superposition model of the laminated plate.The temperature rise state of each position of the gun recoil energy conversion device was determined by establishing the temperature rise calculation model of the gun recoil energy conversion device,with the three-dimensional temperature field model of the gun recoil energy conversion device established and the measures to reduce the temperature rise put forward. Results show that when the complete single shot is fired at a normal temperature environment,the average temperature rise of the stator winding is 1. 05 ℃,which can meet the performance requirements in the condition of continuous artillery firing.
