Abstract:

The purpose of this work is to increase the productivity and accuracy of processing long-length parts of the "shaft" type on CNC machines. Based on the analysis of existing methods for improving the accuracy of processing long shafts on CNC machines, a new method for controlling the spatial error of processing long shafts by changing the processing modes was proposed. The proposed method allows, by changing the processing modes, namely feed, to reduce the radial component of the cutting force and reduce the amount of deflection when machining parts on CNC machines. A technical and economic ana

Abstract:

Shafts over 1.5 m long can be classified as long. Those of them that have a length-to-diameter ratio of more than 10 can be classified as non-rigid. The most characteristic shafts of high precision are the rods of hydraulic cylinders, boreholes of boring machines, cylindrical guides, shafts and rolling pins of various mechanisms, sliding and rolling screws, etc. Processing of such products requires the use of additional devices in machines to overcome the effects of deformations under the influence of cutting forces and gravity, as well as the risk of self-oscillation.

Abstract:

In this study, an effective method based on wavelet transform, for identification of damage on rotating shafts is proposed. The nodal displacement data of damaged rotor is processed to obtain wavelet coefficients to detect, localise and quantify damage severity. Because the wavelet coefficients are calculated with various scaled indices, local disturbances in the mode shape data can be found out in the finer scales that are positioned at local disturbances. In the present work the displacement data are extracted from the MATLAB model at a particular speed. Damage is represented as reduction in

Abstract:

This paper outlines the sweep frequency rotating force perturbation method for identifying the dynamic stiffness characteristics of rotor/bearing/seal systems. Emphasis is placed on nonsynchronous perturbation of rotating shafts in a sequence of constant rotative speeds. In particular, results of the identification of flexible rotor multimode parameters and identification of fluid forces in seals and bearings are given. These results, presented in the direct and quadrature dynamic stiffness formats, permit the separation of components for easy identification. Another example of the perturbatio

Abstract:

The process of deriving the equation of the perturbed motion of a roll pair during the processing of leather material is discussed in the article, taking into account the influence of dynamic factors. It is shown that one of the reasons for the unstable stress state on the contact surfaces in the roller mechanism are dynamic factors arising from inaccuracies in the manufacture of its individual parts, assembly defects, and the occurrence of an oscillatory process in the roller mechanism, as well as due to the non-uniform thickness of the processed material at its gripping during starting and s

Rolling-cut bilateral shear is a sort of auxiliary equipment with arc upper blade performing pure rolling over flat lower one. The working principle are characterized as up-and-down movement of upper blade by crank shaft, after the rotation caused by the phase difference between two shafts, which makes upper blade rotate to adapt to steel shearing with different thickness. Through analysis the processing of rolling-cut bilateral shear and make the shearing mechanism simplify 8-linkage, and then the kinetics formula of shearing mechanism was established.

The analysis of the curvature of the axis of the workpiece, processed on a lathe when based in the centers, using a rest device, is carried out. The formula of elastic displacement of the workpiece axis at the place of the resulting cutting force is obtained. Diagrams of the stresses of the shaft axis displacements are constructed and a conclusion is made. The analysis showed that the greatest deflection is at the poi

Purpose – The purpose of this paper is to present a method for early crack detection in rotating shafts. A rotor-bearing system, consisting of an elastic rotor mounted on fluid film bearings, is used to detect the presence of the crack at a depth of around 5 percent of shaft radius. The fluid film bearings, the shaft and the crack introduce coupled bending vibrations both in the horizontal and vertical plane. Experimental time series of the rotor composite response under normal steady-state operation are uncoupled, to develop a signal processing procedure able to reveal the presence of the cra
