摘要
以无轨胶轮车铰接式车架为研究对象,基于刚-弹耦合动力学理论,利用有限元软件和虚拟样机软件相结合的方法,建立包含弹性体车架的整车刚-弹耦合动力学模型,对车辆在多种路面状况行驶的全过程进行动力学仿真,对车架结构强度和动态性能进行了校核和评估。车架改进后的无轨胶轮车在煤矿应用3年后,检查发现车架主体基本完好,重要结构处无损伤,验证了分析的合理性。
The articulated frame in trackless tyred vehicle was studied. Based on the theory of rigid-elastic coupling dynamics, the whole vehicle rigid-elastic coupling dynamical model which including elastic frame was established by combining finite element software and virtual prototyping software. The dynamic simulation of vehicle driving process on several roads were carried out, and the structural strength and dynamic performance of the frame were verified and evaluated. The trackless tyred vehicle using improved frame was applied in a coal mine for three years. In the overall repair process, the main body of the frame was found intact, and its important structure was no damage. The facts showed that the above stress analysis was reasonable.
