摘要

摘要: 为改善驾驶室的振动情况,提高舒适性,结合某重型矿用自卸车建立了驾驶室的有限元模型,利用ANSYS软件对其进行了模态分析,获取前10阶固有频率和振型;分析了各部件厚度特征对1阶弹性模态和质量的灵敏度情况,根据结果确定变量并对模型机型优化。结果表明:驾驶室在质量没有增加的前提下,1阶弹性模态由35.3 Hz变到45.2 Hz,有效地改善了驾驶室的动态特性。

Abstract: The finite element model for the cab of a heavy mine car is set up and the modal analysis is performed based on the model to get first ten order frequencies of the cab. Comparing the sensitivities of the first order torsion modal frequency to thickness and mass of main parts by the finite element method,the large absolute value of relative sensitive cab's panels are selected as design variables for structural optimization. The optimization results show that the first order modal frequency of the cab is changed from 35.3 Hz to 45.2 Hz while the cab's mass doesn't increase.
