Abstract According to the state of art, worm gears are designed due softer bronze-material wheel primarily against damage because wear, pitting or breakage teeth. The aim research in last decades is optimize load capacity on by using higher-strength bronze alloys, cast iron steel increase transmission gears. This development may lead an increased number cases shaft. In literature, documented to...

Abstract Roll forming is a continuous process in which moving metal sheet passes through numerous pairs of opposing rolls. The shafts the roll mill are equipped with these rolls and must be set up aligned to achieve required final profile sheet. practically relevant task predicting geometry this incremental rolling varying characteristics entering requires an accurate description stiffness beha...

Precise needle placement is required for the success of a wide variety of percutaneous interventions in medicine. Insertions into soft tissues can be difficult to learn and to perform, due to tissue deformation, needle deflection and limited visual feedback. Little quantitative information is known about the interaction between needles and soft tissues during puncture, and no effective physical...

A B S T R A C T Pump shafts used for power generation are susceptible to fatigue cracking while often in near-continuous operation. Technology based on torsional vibration is under development for condition-based assessment of shaft health. The focus of this paper is on the relationship between a crack, which propagated due to bending loads, and the torsional stiffness of the shaft. An analytic...

based on two-dimensional plane stress and bifurcation functional from hill's general theory in polar coordinate the critical condition for elastic wrinkling of the flange of a circular blank ( the wave number in the flange and wrinkled area) during the deep-drawing process are obtained analyticaly to improve the previous given results. in this analytical study, the elastic limitation of the mat...

The shaft bearing is the key component of water pump and its fatigue failure results in abnormal operation system. However, mechanisms are still unclear. In this paper, analysis on engine was carried out by using measurement material composition properties, observation macro micro morphologies, theoretical failure. wear behavior were clarified, prevention measures further proposed. reflected fr...

Abstract This study explains a coherent flow for designing, manufacturing, analyzing, and testing tunable anti-roll bar system formula student racecar. The design process starts with the analytical calculation roll stiffness using constraining parameters such as CG (Center of Gravity) height, total mass, weight distribution in conjunction suspension geometry. Then, material selection i.e. Alumi...

A diffraction theory of continuous-wave photothermal deflection (PD) spectroscopy with fundamental and harmonic responses is presented. The displacement of the probe beam centroid is found to be a rigorous measurement of PD effect, which leads to a set of analytical solutions to the fundamental and the second-order harmonics. Harmonics are caused by the diffraction of the probe beam in the mira...
