Health monitoring using vibration technique is usually conducted on cable structure. The hanger cable on the suspension bridge has a difference of span. To predict axial force of cable, the beam-string theory includes a parameter of bending stiffness. However, string theory has neglected the effect of bending stiffness. The shorter the span of the cable the greater the effect of the bending stiffness would be. This paper raises parameter moment of inertia to span ratio (I/L) to determine the apropriate analytical formula between string and beam-string. Experimental research was conducted using a vibration technique. The specimens use solid cylindrical steel beam, having length specimens of 2 m, hinge-hinge of boundary condition, and difference variations I/L of 0.024, 0.08, 0.58, 1.53 and 10.22. Numerical analysis was simulated by using Abaqus software v 6.13. The result shows that the ratio of I/L equally lowers than 0.082 has close to the analytical string theory. The ratio of I/L greather than 0.082 has close to the beam string theory.

This paper presents an analysis of the effect of tension on machining stability. It studies the mechanism of a self-excited vibration process by applying a tension force in the axial direction in a turning operation. This research investigates the tension effect on machining stability and develops a comprehensive model for the simulation of stability resulting from the axial tension force in machining, particularly for those applications in cutting long, slender, or thin materials. In addition, a new tension-fixturing technology is introduced to maximize stability and minimize undesirable chatter vibration in machining. The research can lead to a better understanding of stability and control of the cutting processes. It also can improve the traditional clamping method and provide important information in the design of the machine tool system, as well as in the planning, optimization, and production control for cutting processes. Following the theoretical analysis, an experimental study on chatter boundary illustrates the tension effect on machining stability. A comparison between the predicted and experimentally measured stability boundary, over a range of cutting conditions, shows favorable agreement.

ABSTRACT: This article focuses on steel cord deformation and force investigation within heavy-duty radial tires. Typical bending deformation and tension force distributions of steel reinforcement within a truck bus radial (TBR) tire have been obtained, and they provide useful input for the local scale modeling of the steel cord. The three-dimensional carpet plots of the cord force distribution within a TBR tire are presented. The carcass-bending curvature is derived from the deformation of the carcass center line. A high-efficiency modeling approach for layered multistrand cord structures has been developed that uses cord design variables such as lay angle, lay length, and radius of the strand center line as input. Several types of steel cord have been modeled using the developed method as an example. The pure tension for two cords and the combined tension bending under various loading conditions relevant to tire deformation have been simulated by a finite element analysis (FEA). Good agreement has been found between experimental and FEA-determined tension force-displacement curves, and the characteristic structural and plastic deformation phases have been revealed by the FE simulation. Furthermore, some interesting local stress and deformation patterns under combined tension and bending are found that have not been previously reported. In addition, an experimental cord force measurement approach is included in this article.
