摘要 随着带式输送机向着大型化的方向发展,动态特性对其运行的稳定性与安全性的影响效应增大,对带式输送机动态特性规律的研究成为保证其安全可靠运行的关键问题之一。基于复杂系统建模仿真平台Amesim,搭建了外置拉紧装置的带式输送机的虚拟样机模型,研究了启制动时间、运行速度对带式输送机的动态特性影响的变化规律,得到输送带达到破断张力时启制动时允许的最短时间、最高运行速度。同时,分析了输送距离、输送带阻尼和输送带刚度对带式输送机动态特性影响的变化规律。该研究为大型带式输送机的设计和使用提供理论依据。 The trend towards the development of the large-scale beh conveyor leads to an increased effect of the dynamic characteristics on its running stability and security, thus necessitating the research into the law underlying the dynamic characteristics of belt conveyor the key to ensuring the safe and reliable operation. The study building on Amesim, one of a complex system modeling simulation platforms works towards the development of the virtual prototyping model of the external tension device and the investigation into the changing law behind the effect of starting and breaking time and running speed on the dynamic characteristic of belt conveyor. The research provides the shortest time and highest speed allowed for the conveyor belt as it reaches the breaking tension during the start-stop time and identifies the changing rule behind the effect of damping and transmission distance on the dynamic characteristics of belt conveyor. The work may serve as the theory basis for design and use of large belt conveyors.
