| 摘 要： | 以AD250铰接式自卸车橡胶弹簧悬架系统为研究对象，运用虚拟样机技术，在不同载荷和车速下对其进行了动力学仿真分析，仿真结果与实验结果具有很好的一致性，表明所建模型是准确的；分析表明，前悬架橡胶弹簧刚度的非线性特性能满足前悬架在不同载荷下具有等支承频率，从而保持稳定的行使平顺性要求；而后悬架系统在轻载荷下较之重载荷时具有较高的支承频率。分析的结果为橡胶弹簧悬架系统进一步优化设计提供了理论支持。

| Abstract: | Virtual prototyping technology has been used to analyze the dynamic characteristics of rubber spring suspension of AD250 articulated dump truck. Multi-body dynamics simulation of the ride comfort has been performed under different velocity and different load. The results of analysis are consistent with experiment results, which shows the correctness of the model. Results indicate that the good and constant ride comfort can be satisfied under different load because of the nonlinear properties of rubber springs of front suspension. Rear suspension system under light load has higher supporting frequency than under deadweight. The results provide a basis for the parameter optimization of rubber spring suspension. |
