Abstract

Design Principles of Horizontal Drum Machines with Low Vibration

Highlights

Rotary mechanisms are used in many areas of modern industry, including mechanical engineering and computer technology
The problems of reducing vibration excited by rotating rotors and having the frequency of the first rotor harmonic are among the most important in the design, manufacture and operation of almost all types of modern rotary machines
The washing machine is of particular interest as an object of study of dynamics and reduction of vibrations and noise, since due to the constant presence of randomly located and wandering imbalance of laundry in the drum and low requirements for the accuracy of its manufacture and assembly of parts and assemblies, so as not to increase the cost

Summary

Introduction

Rotary mechanisms are used in many areas of modern industry, including mechanical engineering and computer technology. Often these mechanisms must operate at high speeds. The problems of reducing vibration excited by rotating rotors and having the frequency of the first rotor harmonic (rotor vibration) are among the most important in the design, manufacture and operation of almost all types of modern rotary machines. Rotary vibration largely determines the reliability of such machines, which are characterized by: high rotational speeds, relatively low structural rigidity, critical modes are often located within the operating ranges of angular velocities. The washing machine is of particular interest as an object of study of dynamics and reduction of vibrations and noise, since due to the constant presence of randomly located and wandering imbalance of laundry in the drum and low requirements for the accuracy of its manufacture and assembly of parts and assemblies, so as not to increase the cost
