Many previous studies have mainly focused on the effects of riveting parameters single-row riveted lap joints. Little attention has been paid to multi-row The outer rows a normal joint usually bear larger part tensile load. However, none relate phenomenon squeezing displacement combination joint. To improve performance three-row joint, this paper aims reveal internal relation between load distr...

The present paper concerns developing an automated system for non-destructive evaluation of riveted aluminium joints. The system features an innovative eddy-current probe providing high sensitivity at low inspection frequencies and a computational tool aimed both at computer-aided electromagnetic design of the probe and quantitative reconstruction of detected defects (inverse problem). The appr...

the paper investigates into the vibrational characteristics of the truck chassis including the natural frequencies and mode shapes. truck chassis forms the structural backbone of a commercial vehicle. when the truck travels along the road, the truck chassis is excited by dynamic forces caused by the road roughness, engine, transmission and more. modal analysis using finite element method (fem) ...

Long-leg bracing affords ambulatory potential and helps reduce the incidence of deformity in patients with paralysis or weakness caused by lesions of the spinal cord. The conventional long-leg brace or knee-ankle orthosis (KAO) consists of double metal uprights, drop locks or bail locks at the knee, double action ankle joints with anterior and posterior pin stops, metal stirrup, and steel shank...
