摘要
针对载重汽车上平衡悬架易产生局部微裂纹,甚至导致断裂破坏事故的问题,运用Pro/ENGINEER和ANSYS分别对直式、U形和圆弧弯形载重汽车平衡悬架进行几何建模、有限元建模和网格划分,结合车辆和平衡悬架的结构参数,施加合理的边界条件,分析平衡悬架关键部件心轴在水平路况和颠簸路况下的应力分布.这3种平衡悬架的心轴应力计算结果表明,直式平衡悬架的强度优于其他两种悬架结构.
As to the problem that micro-cracks are easy to produce on balance suspensions of trucks,which even lead to fracture failure accidents,geometry modeling,finite element modeling and meshing are performed on vertical,U-shape,and arc bending balance suspensions.Considering the structural parameters of truck and balance suspensions,the stress distribution of spindles(key component of balance suspension) is analyzed under plane road and bumpy load by loading rational boundary conditions.The calculation results of spindle stress of the three kinds of structures are compared and indicate that the strength of vertical balance suspension is superior to the other two kinds of structures.
