摘要
为了能准确地测得火炮发射时身管内膛壁的瞬时温度,引进导热反问题技术,通过火炮射击过程中测量身管外壁的温度反演推算出内膛壁温度。提出了运用三维建模软件对导热反问题在身管中的应用仿真,利用有限元分析对仿真模型进行计算的方案。
In order to accurately measure the instantaneous temperature of the body tube wall during artil- lery launch, this paper introduced an inverse heat conduction problem technology, through the artillery fir- ing process to measure body temperature of the outer wall of the tube wall temperature calculation. It pro- posed using 3D modeling software of the barrel application simulation, and using finite element analysis software simulation model calculation procedure.
