针对矿用防爆胶轮车井下作业时受力复杂的特点,分别建立了车体多体动力学模型和车架有限元模型。应用虚拟样机技术模拟真实的工况,提取搓板路面工况下随机激励的峰值,进而通过有限元法对车架进行动态应力分析。有限元分析结果表明整个车架的最大动应力满足强度要求。
In view of the complex force characteristics of mine explosion-proof rubber tire working underground, the multi-body dynamic model and the finite element model of the frame are established respectively. Virtual prototype technology was used to simulate real working conditions and the peak of random excitation under the condition of washboard pavement was extracted. Then the dynamic stress analysis of the frame was carried out by finite element method. Finite element analysis results show that the maximum dynamic stress of the whole frame meets the strength requirements.
