Dynamic Characteristics Study of Belt Conveyor Based on Virtual Prototyping

Abstract

With the improvement of the load and speed of belt conveyor, the dynamic characteristic problem of belt conveyer appears especially outstanding. This paper analyzed the force situation of the conveyer by the discrete dynamics model, divided n viscoelastic properties mass units in advance, then built system analysis dynamics model by vibration mechanics, built modal neutral file of the flexible belt block by means of finite element analysis software, and built the virtual prototype model of the belt conveyor using ADMAS program. It analyzed the effect of stiffness and damping of belt on the starting process by dynamic characteristics simulation method. The simulation results showed that the speed wave period of belt with the smaller stiffness was longer and the peak was bigger, the belt speed easily occurred stronger surge, the transverse vibration of belt conveyor became more violent. With the increasing of stiffness, the belt speed wave peak value decreased. As the same time, the speed surge also decreased when other operation parameters of the belt conveyer system are fixed, with increasing of the damping, the dynamic tension force peak became smaller gradually, it led to decrease of vibration curve peak. Damping coefficient played the important role in decreasing the vibration intensity, the research result offers a new basis for the analysis and study of the dynamic characteristics of belt conveyor.

Dynamics modeling and simulation of steel cord conveyor belt based on dynamic elastic modulus

“…q 0 is the total mass after deformation. Substituting q 0 into equation (12) and deriving for T gives:…”

“…Over the past few decades, various modeling tools and dynamics simulation software have been developed for the dynamic analysis of belt conveyors, such as RecurDyn, AMESim and other dynamics modeling and simulation software. [10][11][12] Numerous mechanical models and simulation algorithms have been developed in previous studies to describe the dynamic characteristics of conveyor belts. The results indicate that classical solid models and Kelvin models can effectively describe the mechanical properties of steel cord core conveyor belts under loading conditions, and the constitutive models of steel cord core conveyor belts can accurately capture their dynamic behavior during operation.…”

Effects of tooth profile and belt speed on cogged V-belt vibration and stress

“…Several scholars have studied the dynamic performance of synchronous belts with different tooth forms and the transmission optimization of a synchronous belt [2][3][4][5][6] and obtained the vibration and stress distribution of such a belt for various tooth forms. A number of researchers have performed transmission simulations of the ordinary V-belt, flat belt and multi-wedge belt [7][8][9]. Although the various experts use different research methods [10][11][12], the most commonly used approach is rigid flexible coupling simulation based on a modal flexible body [13,14].…”
