摘要:
为了提高AD250铰接式自卸车的平顺性,对其平衡悬架夹层橡胶弹簧的刚度进行了分析和优化.建立了橡胶弹簧的参数化有限元接触模型,对弹簧轴向刚度的非线性特性进行了分析,分析结果与实验结果能很好地吻合.研究结果表明, 此橡胶弹簧刚度偏大且非线性特性不能满足悬架在不同载荷下具有等固有频率的要求,为此以固有频率2 Hz为优化目标对橡胶弹簧的参数进行了优化,优化后的橡胶弹簧能使车辆保持稳定且良好的平顺性.
Abstract:
The ride comfort of AD250 articulated dump truck is improved through analysis and optimization of the stiffness of laminated rubber spring in balanced suspension. The parameterized contact finite-element model of spring has been built, and non-linear stiffness in vertical direction has been analyzed in this paper. The result of analysis is consistent with experiment results very well. Results indicate that the improper nonlinear stiffness properties of rubber springs may lead to different natural frequency of rear suspension system under different load, resulting in poor side comfort. The structure parameters of rubber spring is therefore optimized to achieve a suspension natural frequency of 2 Hz. The optimized rubber spring presents a good and steady vehicle ride comfort.
