Drawing or forming is a process normally used to achieve a required component form from a metal blank by applying a punch which radially draws the blank into the die by a mechanical or hydraulic action or combining both. When the component is drawn for more depth than the diameter, it is usually seen as deep drawing, which involves complicated states of material deformation. Due to the radial d...

BIS Working Papers are written by members of the Monetary and Economic Department of the Bank for International Settlements, and from time to time by other economists, and are published by the Bank. The views expressed in them are those of their authors and not necessarily the views of the BIS. Limited extracts may be reproduced or translated provided the source is stated.

The human red blood cell is a remarkable transport system, perfectly suited to its task. Its cargo, hemoglobin, is carried effortlessly throughout the body, where it is serves as a molecular shuttle for oxygen and other gases. Although the red blood cell is not itself motile, it leads a very dynamic existence in the circulatory system. During the course of its travels it must be durable enough ...

This study presents a novel shock absorber with an inward-inverting composite foam-filled tube. Under the compression of pressing cap and action internal inversion cap, tube inverted inward. During crushing, fronds compacted foam, thereby enhancing energy absorption. Three types foams were applied to absorber, drop-weight impact test was performed obtain assessment parameters. The foam increase...

Title of Document: ADAPTIVE MAGNETORHEOLOGICAL SEAT SUSPENSION FOR SHOCK MITIGATION. Harinder Jit Singh Doctor of Philosophy, 2014 Directed By: Norman M. Wereley Minta Martin Professor and Chair Department of Aerospace Engineering This research focuses on theoretical and experimental analysis of an adaptive seat suspension employing magnetorheological energy absorber with the objective of minim...

Abstract In order to study the influence of structural factors launch device on missile tilt projectile dynamics, a dynamic model platform was established based finite element method. The effects shock absorber stiffness, angle between and horizontal plane were studied platform’s ejection response characteristics. research results show that greater rigidity absorber, smaller plane, vibration am...

The article covers the forces acting on sewing machine links and vibrations in caused by these forces, failures faults vibrations, impact of quality. A dynamic model flexible shock absorber mechanism with elastic elements has been developed theoretical problems have solved, nature parameters stresses determined.

In an automotive industry, to reduce product development time and increase quality of product, it is essential to reduce the number of physical prototypes and rely more on precise & reliable design for the final design of vehicles. This paper presents a mathematical model for the damping force of the hydraulic shock absorber which is implemented to analyse the shock absorbers mounting brackets ...

The various process parameters affecting the quality characteristics of the shock absorber during the process were identified using the Ishikawa diagram and by failure mode and effect analysis. The identified process parameters are welding process parameters (squeeze, heat control, wheel speed, and air pressure), damper sealing process parameters (load, hydraulic pressure, air pressure, and ...
