TECHNOLOGY OF SHAFT MECHANICAL GEAR REPAIR USING CONSUMABLES GROUP LOCTITE

Passive Landing Gear using Coupled Mechanical Design

The ability of UAV’s (Unmanned Aerial Vehicles) to land on unknown and uneven terrain is an important area of research, particularly for applications such as field surveillance. This paper presents a novel solution to this problem using mechanical design, with a legged landing gear design that provides both suspension and stability on uneven terrain. The key features of this design are differen...

Strength Check Analysis for Gear Shaft of Automobile Transmission

As the main drive components of the automobile transmission, the performance of gear shaft plays an important role on transmission performance. Aiming at the existing problems of the traditional strength check method of gear shaft, the objective of this study is to take a five-speed transmission as an example, to accomplish the strength analysis of gear shaft of the automobile transmission base...

Direct Cartilage Repair Using 3D Bioprinting Technology

INTRODUCTION: Articular cartilage is commonly injured and current tissue engineering strategies cannot as yet fabricate new tissue that is indistinguishable from native cartilage with respect to zonal organization, ECM composition, and mechanical properties. Almost all current strategies of cartilage repair involve a procedure of removing healthy cartilage tissue around the lesion to create art...

New technology: valve repair using biodegradable rings.

OBJECTIVE To introduce a new concept in the annuloplasty technology. Although rigid and flexible rings meet the basic needs of adults, they do not preserve the changes in shape and size occurring during the cardiac cycle. If implanted in children, such materials do not allow growth of the native annulus. METHODS From March 2003 to March 2007, 207 patients underwent mitral and/or tricuspid val...
