摘要
以A356铝合金车轮的低压铸造工艺为对象,建立了计算车轮弯曲疲劳寿命的数学模型,利用铸造模拟技术和有限元分析,研究了二次枝晶臂间距及最大针孔尺寸对车轮力学性能的影响,并验证了该方法的有效性。
Taking A356 aluminum alloy wheels made by low pressure casting process as research object, a mathematical model for calculating the bending fatigue life of the wheel was established, and the effects of two secondary dendrite arm spacing and maximum pinhole on the mechanical properties were studied by simulation technology and finite element analysis, and the effectiveness of the proposed method was verified.
