Inspection on Ball Bearing Malfunction by Chen-Lee Chaos System

A Hamilton-Poisson Model of the Chen-Lee System

Implementation of the fractional-Order Chen-Lee System by Electronic Circuit

In recent years, there has been an expanding research on the applications of fractional calculus to the areas of signal processing, modeling, and controls. Analog circuit implementation of chaotic systems is used in studying the nonlinear dynamical phenomena, as well as applied in realizing the controller development. In this paper, chain fractance and tree fractance circuits are constructed to...

Experimental Investigation on Radial Ball Bearing Parameters Using Taguchi Method

In this work, characteristics of various ball bearing parameters are studied under different loads and rotational speeds. By using Dimensional Analysis (DA), dimensionless parameters are computed which provides solution for a group of parameters. This analysis can be accomplished by using the Buckingham π-theorem. DA leads to reduction of the number of independent parameters involved in a probl...

Ball-Bearing Motor

The discovery/invention of the ball-bearing motor is attributed to Milroy [1]. It has been discussed several times, with conflicting explanations [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]. This solution is a much simplified version of that given in [7]. Because the motor is weak, it is helpful to reduce friction on the axle by connecting the high-current lead to the outer races of the ba...

B Ball Bearing ▶ Bearing Bar Extrusion

Introduction Bar extrusion is a process in which a block of metal (billet) is forced to flow by compression through a tool (die) opening of a smaller crosssectional area than that of the original billet. There are two basic types of bar extrusion: direct and indirect. The most important and common method used is the direct extrusion (Lange 1988). Figure 1 shows the principle of direct bar extru...
