Abstract:

提出了一种采用计算流体力学(CFD)计算的压力分布对活塞理论气动力进行静压修正的方法,将该方法应用到曲壁板的静气动弹性变形及颤振稳定性分析中,并与采用曲率修正活塞理论气动力的计算结果进行了对比。分析结果表明,采用本文提出的活塞理论气动力静压修正方法进行曲壁板的气动弹性分析,在圆柱曲壁板曲率较小的情况下,与采用曲率修正活塞理论气动力方法得到的静气动弹性变形、稳定性边界差别不大;而在曲率较大时,采用本文方法计算得到的曲壁板静气动弹性变形,其曲壁板靠近前缘部分被压的更低,而曲壁板的颤振稳定性边界更小,且这种差别随着圆柱曲壁板曲率的增加而不断增大。该方法突破了曲率修正活塞理论的小曲率限制,扩大了活塞理论气动力在曲壁板颤振分析中的适用范围。
