Possibilities for regulation of distribution of oscillation amplitudes points of working bodies of technological machines

Abstract

Ensuring the reliability of technological equipment is determined by the dynamic characteristics of operating modes. For objects in the form of extended solids that perform flat or spatial movements, the distribution of oscillation amplitudes at the points of the working body is essential. The problem of adjusting the vibration field of a technological machine is considered. The solution uses methods of structural mathematical modeling, when a mechanical oscillatory system, considered as a computational scheme of a technical object, is compared to a structural mathematical model in the form of the structural diagram of a dynamically equivalent automatic control system. A method for forming certain structures of the vibration field of technological machines is offered. The method is based on the use of additional links implemented by special devices for converting movement. Selection of parameters of a vibrating technological machine by using the effects of changing the reduced mass of devices for converting motion, made in the form of screw non-self-braking mechanisms. The developed mathematical models reflect the vibration field of a homogeneous structure created by “zeroing” angular oscillatory movements. The proposed method for setting the vibration stand parameters is illustrated by computational modeling on the example of a model problem.
