TL3400矿用自卸车平衡悬架有限元分析

Finite Element Analysis of the Balance Suspension for TL3400 Mineral Self-dumping Truck

针对TL3400矿用自卸车平衡悬架在使用中存在的问题,利用有限元软件Ansys/LS-dyna建立了悬架有限元模型;在不同载荷和不同板簧宽度条件下,对平衡悬架进行了有限元分析。在建立实验模型之后,进行实验比较。结果表明,适当增加钢板弹簧宽度,可以有效降低结构位移量,为消除故障提供依据。

A finite element model of the balance suspension of TL3400 mineral truck was established by using ANSYS/LSDYNA software. According the proposed model, finite element analyses were carried out under different loads and different spring widths. The experiment results showed that displacement of the structure could be reduced by properly enhancing spring width, as to eliminate the potential failure.
