摘要
由于悬架组件具有复杂的非线性弹性力学行为,往往需进行1个或者多个试验,以了解其弹性力学行为。随着计算机计算能力的提高,利用数值分析解决工程问题的能力大大提升。本文利用有限元分析软件ANSYS建立了悬架组件的有限元模型,应用APDL语言控制不同载荷步中对模型的加载、求解以及后处理,提取有限元模型中关键节点的坐标和位移,分析计算了不同转矩下转角的大小,最终获得旋转刚度曲线图。
Suspension components are also called elastic bearings, due to its complex nonlinear elastic mechanical behav- ior, engineers tend to design one or more experiments to understand its elastic mechanical behavior in the enterprises. With the improvement of computer computing ability, numerical analysis was used to solve engineering problems to improve the engineering ability greatly. The paper established the finite element model of suspension components by using finite element analysis software ANSYS, and by using APDL language to control different load steps in the model of load, solving and post-processing, coordinates and displacement of the key nodes in the finite element model were extracted, the size of the angle was calculated under the different torque, in the end, rotational stiffness curve was obtained.
