Abstract Analysis of dynamic characteristics the defective bearing is significant for fault diagnosis machinery. At present, there are few researches on numerical modeling with roller. To solve this problem, explicit finite element method adopted in paper to establish a nonlinear model cylindrical roller spalling defects. In proposed model, flexibility all components, internal friction, relativ...

Automatic guided vehicles with omnidirectional wheels have three degrees of freedom (DOF), their full mobility being obtained by virtue of the free rollers around the periphery of the wheels. The choice of the orientation of the roller axes with respect to the wheel axis, along with the wheel orientations with respect to the platform, the number of wheels, etc., are design issues considered her...

The testing of roller rotational resistance is essential in improving and searching for new design solutions to reduce the energy consumption belt transport. publication presents three methods idler using various laboratory test stands designed built by authors. According first method, consists applying torque axis measuring force rotate axis. second consisted speeding up idler, free stopping t...

When transporting bulk cargo at long distances, modern high productive belt conveyors must be equipped with energy-saving conveyor belts, which can reduce the energy consumption of drive by 28%, and negative impact on environment, including ESG principles. Formula is proposed to determine mass emissions harmful substances into atmosphere - carbon dioxide, nitrous oxide solid particles depending...

This paper presents navigation system for an omni-directional AGV (automatic guided vehicle) with Mecanum wheels. The Mecanum wheel, one design for the wheel which can move in any direction, is a conventional wheel with a series of rollers attached to its circumference. The localization techniques for the general mobile robot use basically encoder. Otherwise, they use gyro and electronic compas...

Now a days the Consumption of power has been increased tremendously. In order to meet the demand of Power by various units various setups has been introduced for effective power generation. In this Project electrical power is being generated as non-conventional method by simply passing vehicles on to the specially designed Roller Setup. This method of Electrical power generation needs no input ...
