Analysis for effects of kinematic parameters on foreign object damage of blades 运动参数对叶片外物损伤的影响分析
Effects of centrifugal stress on foreign object damage of blades 旋转离心应力对叶片受外物损伤的影响研究
Experimental technique for investigation on foreign object damage of Aeroengine 航空发动机外物损伤试验技术研究
Ago, investigating means often use experiment on model to simulate foreign object damage and its effect to fatigue lifetime of blade, mensurate remainder fatigue lifetime, but fatigue experiment itself has localization and the cost is high. 以往的研究主要采用试验方法,通过模型试验模拟外物冲击对叶片疲劳寿命的影响,测定剩余疲劳寿命,但试验本身具有局限性而且成本较高。
In this paper, the effect of Foreign Object Damage(FOD) on the fatigue life of compressor blades and the repair scale of the FOD blades were investigated. 本文对进气边遭受外来物损伤的叶片的疲劳寿命进行了试验研究。
