Research On Steering Dynamic Characteristics Of

In recent decades,belt conveyor has gradually become the main conveyor transport of bulk material continuous transport equipment subject.With the continuous advancement of technology,the proportion of belt conveyor system is growing in the actual production work,more and more significant advantages of belt conveyor have been found,so this efficient delivery tool is being used in a lot of complex environment such as,post-disaster reconstruction,flood rescue and other working conditions places.Although in recent years,the level of turning conveyor in theory and practice have achieved a certain degree of improvement,but it still remains in the form of fixed rack conveyor,so it is difficult to meet the diverse needs of the site.Therefore,it is extremely important to research for moving or turning to independent conveyor.Currently,a new type of belt conveyor has been developed,its main conveyor rack is different from ordinary chassis,it can achieve self-moving and relatively among its racks rotation of a certain angle.Therefore,making deeply research and analysis of its dynamics provides a theoretical basis and practical experience for further improving the serpentine belt conveyor.This paper regards the serpentine belt conveyor as the main object,it focused on solving dynamics instability analysis of the problem of serpentine belt conveyor in steering the course of generated situation.And it discussed the existing situation,the results of theoretical of belt conveyor and the problems which existed now in design theory to provide a theoretical basis for the design of industrial design.Firstly,this paper introduces the working pricincple,structural features and associated parameters of serpentine belt conveyor throught he research on the existing serpentine belt conveyor and on the basis of existing research results.And it conducts the research on kinematic characteristic and simulation analysis of serpentine belt conveyor.Secondly,the operation of the conveyor belt were calculated and analyzed in the process of turning,and then it conducts the analysis of steering mechanism theoretical turning on the serpentine conveyor,establishes the nonlinear dynamics model of serpentine belt conveyor steering and analyzes the species of instability of serpentine belt conveyor which occur in steering.Then,it makes nonlinear theory analysis of its occurrence during steering instability and influencing factors by using the theroy of nonlinear.Finally,it lays the theoretical foundation for the further research on dynamics nonlinear characteristics of serpentine belt conveyor system.
