摘要
对典型连接形式长叶片的围带阻尼减振特性进行理论研究,利用Abaqus有限元软件对典型结构连接形式长叶片进行瞬态显示动力学仿真,得到了外载荷所做功、摩擦力消耗功等动力学特性,并定义了摩擦阻尼减振量化因子,给出围带摩擦阻尼特性量化方法。在此基础上分析了典型结构连接形式长叶片阻尼减振特性,通过分析比较,围带长叶片的减振效果较好,自由叶片没有减振效果。
This paper makes a theoretical study on the damping and damping characteristics of the long-blade with typical connection form,and uses Abaqus finite element software to simulate the transient display dynamics of the long-blade with typical structural connection form.Based on this analysis,the damping characteristics of long blades in typical structural connection form are analyzed.Through analysis and comparison,the damping effect of the long blades in the belt is better,and the free blades have no damping effect.
