| 摘 要： | 研究了某型压气机第一排转子叶片最大挠度相对位置对颤振的影响.首先通过调整转子叶片最大挠度相对位置,对叶片表面非定常气动力及其所做非定常气动功进行计算分析,然后采用能量法对叶片颤振与否进行预估判断.计算结果表明,该型压气机第一排转子叶片最大挠度相对位置分布不均匀会大大提高颤振发生的可能性,而最大挠度相对位置越大,发生颤振...

| Abstract: | The article focuses on the relationship between compressor blade deflection and blade flutter.First its unsteady flow force and work are calculated through adjusting blade deflection location.Then,the probability of flutter is estimated by using the method of energy.The calculation results show that the uneven of deflection location will enhance the possibility of flutter.The greater deflection location is,the smaller the possibility of flutter occurred.The results have great help for compressor mechanism r... |
