The consequences of recent experimental finding that hydrogen bonds of the antiparallel β-sheet in nonspecific binding site of serine proteases become significantly shorter and stronger synchronously with the catalytic act are examined. We investigate the effect of the transformation of an ordinary hydrogen bond into a low-barrier one on the crankshaft motion a peptide group in the anti-paralle...

In this paper the effect of quadratic and cubic non-linearities of the system consisting of the crankshaft and torsional vibration damper (TVD) is taken into account. TVD consists of non-linear elastomer material used for controlling the torsional vibration of crankshaft. The method of multiple scales is used to solve the governing equations of the system. Meanwhile, the frequency response of t...

Using finite element method and multi-body dynamics method, this study established an engine digitalized virtual prototype embraced tribological characteristics in virtual prototype and MATLAB platform, and introduced Elastohydrodynamics theory into the system, wrote program with difference equation method, and solved the Reynolds Equation through shafting-bearing self-feedback control system, ...

At present, electromagnetic induction quenching and nitriding are two commonly used surface strengthening approaches applied in improving the strength of steel parts. In this paper, a comparative study was proposed to research effect these technologies fatigue crankshaft. First modified statistical analysis approach limit load obtain distribution load. Then types crankshafts were selected be ob...
