摘要
建立矩形截面叶片密封的接触压力数值模型,研究预压缩量对密封面接触压力的影响。分析结果表明,叶片密封的密封面接触压力随预压缩量的增加而增大,但不同方向的预压缩量对接触压力的增大效果并不相同。在本研究条件下,y向预压缩量导致的最大接触压力增长梯度明显大于z向预压缩量导致的最大接触压力增长梯度,要提密封面的接触压力,增大y向预压缩量效果更为明显。
A numerical model and program was developed to study the effects of the initial interference of vane seals to sealed reliability of flexible windows shape vane seals with rectangular cross section.The computing results show that the initial interference of vane seals increases the contact pressure.The effects of the initial interference in y and z direction are very different,that is say,the y-direction interference causes more significant effects on y and z direction contact pressure than the z-direction one does.
