Optimization of the Conveyor Drive Parameters under Stochastic Loads

Lack of information about operation of a machine under new conditions is one of the problems that designers face when designing a machine drive. Average values based on the analysis of existing equipment are usually used. In most cases, they are of little use due to changes in the technological process and modernization of the machine. In this study, the authors simulated the operation of a conveyor belt drive and optimized its parameters under stochastics loads. A model of the system was developed that reflected design and technological features of the machine and its interaction with adjacent equipment. The model contains geometric, kinematic and dynamic characteristics of the system and describes logical and functional dependences between the parameters of the drive and the characteristics of the system. Various drive operation modes (constant, variable and probabilistic) can be reproduced using the model.  The duration of the simulation of the drive operation may vary from a few minutes to several hours or shifts.  The accuracy of the simulation with regards to time is 0.1 sec, to space — 1 cm. There is a tool for collecting and processing statistical data, such as the drive power, torque on the drive shaft of the machine, etc.
