Research on Control System of Belt Conveyor Hydraulic Auto Take-up

大型 带式输送机液压自动 拉紧 装置控制系统研究

The kinetic model of starting and stopping processes is established to study on the dynamic design question of the large belt conveyor . The resistance action is comprehensively considered the belt is visco elastic and the take-up pull has two freedoms in the kinetic model .

针对大型带式输送机动态设计问题，建立了起动和停机过程的动力学模型，其特点是综合考虑了阻力的作用、输送 带为粘弹性、 拉紧 装置分为2自由度。

In the dynamic equation both the viscoelasticity properties of belt the run resistance the inertia force of take-up the belt 's elastic modulus influented by the deflection of belt and the initial stress have been considered .

所建立模型的动力学方程不仅考虑了 输送 带的粘弹性力学性质、运行阻力、 张 紧 装置的惯性力和输送带挠度变化下的弹性模量，同时也考虑了输送带初始张力的影响。

In this paper the dynamic force and displacement of belt is analysed when conveyor take-up ( automatic and fixed ) requlates belt force and the breakdown born of it is discussed .

分析了 胶带运输机 拉紧 装置（自动 式和固定式）在调整胶带张力时所产生的动负荷及位移，讨论了由此产生故障的原因。
