摘要
为进一步探究双螺杆空压机壳体动态响应特征,以某煤矿用双螺杆空压机为研究对象,建立其壳体结构的三维模型,通过有限元分析方法,对其进行模态分析和动态响应分析.结果显示,虽然该壳体结构不存在共振风险,但其右端盖位置和排气座位置的振动较为剧烈,对实际应用仍存在不利影响.基于此,应用增设加强筋的优化方法对其进行结构优化,结果显示,优化后壳体结构的最大振动位移和最大振动速度都有明显降低,降幅分别达到了6.04％和8.42％,效果较为显著.
Abstract
In order to further explore the dynamic response characteristics of the twin-screw air compressor shell,a three-dimensional model of the shell structure of the twin-screw air compressor used in a coal mine was established.The modal analysis and dynamic response analysis were carried out through the finite element analysis method.The analysis results showed that although there was no resonance risk in the shell structure,the vibration of the right end cap and the exhaust seat was relatively severe.There are still adverse effects on practical application.The results show that the maximum vibration displacement and maximum vibration velocity of the optimized shell structure have been significantly reduced,respectively,by 6.04％and 8.42％.The effect is more significant.
