Study on Fuzzy Comprehensive Evaluation Model for the Safety of Mine Belt Conveyor

To improve the situation of the frequent failures of mine belt conveyor during operation, a model was used to evaluate the safety of mine belt conveyor. Based on the foundation of collecting and analyzing a large quantity of fault information of belt conveyor in the nationwide coal mine, the fault tree model of belt conveyor has been built, then the safety evaluation index system was established by analyzing and removing some secondary indicators. Furthermore, the weighted value of safety evaluation indexs was determined by analytic hierarchy process(AHP), and the single factor fuzzy evaluation matrix was constructed by experts grading method. Additionally, the model was applied in evaluating the security of belt conveyor in Nanliang coal mine. The results shows the security level is recognized to the “general”, which means that this model can be adopted widely in evaluating the safety of mine belt conveyor.

Abstract This article deals with a methodology developed to design and select tensioning systems with using simulation studies on a belt conveyor model. It describes the structure of a dynamic model of a belt conveyor with distributed parameters and details of physical models of the applied belt tensioning systems.

Adaptive Parameter Estimation for an Energy Model of Belt Conveyor with DC Motor

ABSTRACTIn practice, design parameters of a belt conveyor likely drift away from their design values by maintenance, readjustment, retrofit, abrasion, and circumstance change. For the purpose of energy optimization, these parameters should be estimated through experiments. In this paper, a new energy model of a DC motor driven belt conveyor is presented. Then, based on an adaptive observer, a parameter estimation algorithm is derived. In addition, under a persistent excitation condition, the convergence of the parameters to the desired values can also be concluded. Compared with the existing methods, our methods can be implemented by measuring only the feed rate of the belt conveyor and the angular velocity of the rotor of the DC motor.

Dynamic Simulation Analysis of Belt Rupture for Belt Conveyor

To study the dynamic characteristics of belt conveyor during belt rupture, the finite element dynamic model of belt conveyor was built. Dynamic simulation system of DTII type belt conveyor was established with AMESim. The simulation parameters were determined by DTII type belt conveyor design manual and the dynamic model. The speed, displacement of break point and mechanic characteristic carve in break moment were obtained. According to the result, the optimal capture time was confirmed.It provides the theoretical basis for the design of belt rupture equipment.

Dynamic States Specific Analysis for Belt Conveyor Based on FDM

There are two common research methods on the dynamic states model of belt conveyor in China at present. The mathematical model is built by finite element method then it is solved by numerical method. And the continuous model is built when the belt is treated as elastic body then it is solved by mathematical method. This paper puts forward the establishment of continuous model, the model is solved by FDM and the simulation results are given.

Study on Conveyor AMESim Model and Motor Starting Interval

This paper sets up a model of belt conveyor driven by two drive pulleys and three motors based on AMESim. The starting performance of conveyor is studied in three cases of motor starting interval: without time interval, with three second interval, and with five second interval. The conclusion is as following: the longer the time interval, the smaller the impact on the belt, and the acceleration of belt and gravity take-up. The simulation design suggests that three second interval and dual gravity take-ups should be taken. And the output torque of drive system should be reduced by 8—15%.

Simulation and Analysis during Conveyor Stop Process Based on AMESim

This paper builds drive system model of belt conveyor during three kinds of stop process based on AMESim, and deduces belt tension equations. A case study on a long belt conveyor dynamic performance concludes that the braking stop process is shortest and motor stop process is longest. Also, the torque change rules of drive pulley among three kinds of stop process are same, that is increase at the beginning and decrease at last. The displacement of gravity take-up is largest during motor stop process, and the gravity moves far from the original point during power-off stop process.
