The traditional method to calculate bending displacement of helical tooth is generally based on simplified tooth profile. Besides, the unbalance loading is not taken into account. To overcome this disadvantage, a new method to calculate bending deformation of helical tooth is introduced. First, gear section is divided into several copies along tooth width and each section’s moment of inertia is...

It is well known that there is a large variance associated with fatigue life. However, in literature little is found on the relationship between manufacturing processes and fatigue variance of the manufactured components. In this research, the influence of machining processes on the fatigue variance of the machined Ti 6Al-4V samples is studied experimentally. The impact is evaluated by comparin...

Soft limbs with anisotropic stiffness are common in nature and enable animals to solve a variety of tasks, including locomotion and manipulation. This mixture of hardness and softness enables animals to efficiently control the unpredictable contact forces that occur while performing such tasks. A challenge for soft robotics is to create artificial limbs that mimic natural mixtures of hardness a...

We present a novel bending model and constraint creation method for position-based dynamics. Our new bending model is introduced as an alternative to the current state-of-the-art dihedral bending model. Our model is motivated by geometric principles and operates on virtual triangles. It has the same cheap computational cost as the stick constraint model but with higher simulation quality and fa...

The movement of eukaryotic flagella is characterized by its oscillatory nature. In sea urchin sperm, for example, planar bends are formed in alternating directions at the base of the flagellum and travel toward the tip as continuous waves. The bending is caused by the orchestrated activity of dynein arms to induce patterned sliding between doublet microtubules of the flagellar axoneme. Although...

In this study, the impact bending strengths and specific impact bending strengths were determined for solid wood and laminated veneer lumber (LVL) produced from eucalyptus (Eucalyptus grandis W. Hill ex Maiden), poplar (Populus x euramericana I-214), and beech (Fagus orientalis L.) woods using urea formaldehyde (UF), melamine urea formaldehyde (MUF), and phenol formaldehyde (PF) adhesives. The ...

Gas-phase fundamental and CH and CO overtone spectra (700-17 500 cm -I) of 2,2,2trideuteroacetaldehyde were recorded using FTIR and laser photoacoustic techniques. The Fermi resonance structure in the overtone spectra of the coupled CH stretching and in-plane CH bending vibrations is analyzed with a tridiagonal Hamiltonian, yielding a large effective coupling constant, I k ;bb I = 93 cm I, corr...

Dynamics of bending of NaCl whisker is studied with use of high speed camera VFU-1 synchronized with high power electron accelerator GIN-600. The dynamics of bending turns to be non-monotonous and quite complicated. The figures of etching of whisker after bombardment by electron beam are analysed, thin polygonization in samples is found. The time of bending in experiment and time of forming of ...

Abstract--L-shaped beams subjected to pure elastic-plastic bending are investigated thoroughly. The shifting and rotating of the neutral axis of the beam during bending and springback after unloading are described mathematically, while the curvatures of the beam before and after springback are given. The method proposed in this paper is valuable both to the further theoretical studies of the as...
