| 摘 要： | 产品研发过程中,利用CAE方法对新开发的某型号装载机动臂进行强度校核计算,校核发现动臂局部存在应力集中,且承受交变载荷,属于疲劳断裂危险区域。为此,提出了3种解决方案,解决方案各有优劣,需要择优而选。利用ANSYS的疲劳分析模块,建立动臂的疲劳有限元分析模型,计算出改进前、后动臂的疲劳寿命,从而选择出了涉及设计改动最少且可靠性寿命满足使用要求的最佳解决方案。产品投放市场后,动臂的使用寿命情况与分析预测一致,证实了疲劳计算模型的正确性。

| Abstract: | During development procedure of a new loader, strength revision is conducted on its boom with CAE method. It is found that there are stresses concentrations at partial locations, the loads are alternating so these locations are dangerous areas of fatigue fractures. To solve the problem, three solutions with respective advantages are suggested so selection among them is needed. With fatigue analysis module in ANSYS, finite element model of the boom is set up for fatigue analysis and fatigue lives of the boom... |
