摘要
研究了自带冠叶片冠间接触碰撞的动力学特性及减振机理。利用弹性力学理论对叶片冠间接触碰撞问题建立碰撞弹性力模型,叶片的冠间接触碰撞进行了数值模拟,并通过实验验证了理论分析的结果,进而得到了叶片接触碰撞系统的非线性响应特性及减振机理。
The dynamic characteristics and damping mechanism of impact-contact between tips of blades were studied.The model of elastic impact forces for the impact-contact between tips of blades was established by employing the theory of elasticity.Then the impact-contact of blades was simulated numerically and the results were verified by experiments.Finally the nonlinear response characteristics and damping mechanism of impact-contact system were obtained.
