Dynamic characteristics of the conveyor belt

Also called transport conveyor belt, conveyor belt is made of rubber and fabric core or rope core composition. Since the rubber itself is rheological material , coupled with

anisotropic fabric core or very complex heavy duty conveyor situation by force steel cord , which has a very complex dynamics , the deformation and

Load size , history, time, frequency , ambient temperature , material properties and other factors , the main manifestations are:
1 the stress -strain relationship is nonlinear characteristics , dynamic modulus of elasticity is not a fixed value.
2 for a hysteresis characteristic is that when loading and unloading cycle, the strain does not immediately uninstall with loads return to its original position, during which

time history is to have a
Creep Characteristics When sleep Airport conveyor 3 is loaded , the holding load constant elongation of the belt to increase with time , when after a certain time reaches a stable value
4 relaxation characteristics when loaded to maintain constant elongation suffered payload size gradually decreases with time , after a certain time has reached a stable value
5 the frequency characteristic and also the amount of deformation belt loading frequency size.
In industrial production , the correct use of conveyor belt is particularly important , the conveyor belt in the use of the main note the following:
1 to avoid roller covered by material , causing rotation ineffective to prevent leakage of material card in between the tape and the roller , pay attention to the lubrication of

conveyor belt moving parts , but not oil belt ; 2 must prevent belt load start , or will cause serious consequences ;
3 conveyor deviation occurred , to immediately take measures to rectify ;
4 found conveyor local damage , the application of rayon timely repair to avoid expanding , such as not ask professionals ;
5 to avoid being conveyor rack , pillars or massive block of material , to prevent misfortune to scratch the rip .
