摘要
对矿山运输卡车在装载过程中所产生的冲击力对于卡车结构损坏和驾驶员的健康问题进行了较全面的分析,建立了包括材料倾倒的冲击、人体的振动和卡车悬挂系统的动力学模型,并利用数值积分的方法对整个系统的动力响应进行了仿真.
The shovel-truck mining system is widely used in surface mining operations for material excavation and haulage. The impact force due to the load under gravity causes huge vibrations, wear and tear of the dump truck, which is severe for the first load. This paper built an integrated dynamic model including impact model, truck model and human vibration model. Numerical method was applied to solve the differential equation.
