Sungda Conveyor Belt Co.,Ltd.

The dynamic characteristics of the belt conveyor belt are mainly expressed in the following aspects:

(1) The nonlinear characteristics of the stress and strain of the conveyor belt: when the conveyor belt is under tension, the relationship between the tension and deformation does not fully comply with Hooke’s law, but is nonlinear. .

(2) Creep characteristics of conveyor belt: The creep characteristics of conveyor belt means that when the force acting on the conveyor belt remains unchanged, the deformation of the conveyor belt increases with time, until it tends to a certain value. That is, a tensile step stress is applied to the conveyor belt. With the extension of time, the strain change rule of the conveyor belt is different from the stress, but has the characteristic of lagging the stress, and gradually tends to a larger value:

(3) Relaxation characteristics of the conveyor belt: When a constant stress is applied to the conveyor belt, the tensile stress of the conveyor belt will gradually decrease with time, thus tending to a stable value.

(4) Viscous hysteresis characteristics of the conveyor belt: hysteresis occurs during the stretching process of the conveyor belt. Its main performance is that the stress-strain curve does not coincide when loading and unloading, this phenomenon also shows that the conveyor belt has obvious viscoelasticity.

(5) The remarkable dynamic characteristics of the conveyor belt: the deformation of the conveyor belt under the action of tension is not only related to the magnitude and time of the tension, but also to its speed of change. It can be seen that the conveyor belt has obvious viscoelasticity, and the changes of stress and strain during stretching are related to many factors.
