Design Optimization of Linear Vibratory Conveyors

Doctoral thesis

Abstract:

STURM, M. Design Optimization of Linear Vibratory Conveyors. Liberec: Department of Machine Parts and Mechanisms, Faculty of Mechanical Engineering, Technical University of Liberec, 2018. 114 pages dissertation, leading: Prof. Ing. Lubomír PEŠIK, CSc. This dissertation deals with the functional and performance optimization of vibratory conveyors in conjunction with the reduction of vibration to the ground with reference to the needs of practice. Based on an analysis of the current transport process of bulk materials, dynamical models are developed, enabling a systematic modification of the conveying process. With regards to the results of the developed modification possibilities, an efficient model for the optimum transport of the goods by simultaneous reduction of vibration transmission to the ground is developed. To achieve the goal of this dissertation, a comprehensive dynamic analysis and optimization of the transport process is done, both with regard to the correct tuning of the vibratory conveyor and maintaining the required dynamic parameters, as well as with regard to the mechanical properties of the transported objects. Based on the results of the optimization dynamic parameters are proposed and measured. Some of them are implemented into functional samples in which the theoretical knowledge is verified by measurements of kinematic variables.
