Reliability assessment of reciprocating equipment piston rod leads to nonlinear elastic-plastic deformation analysis of rod with initial imperfection under axial dynamic load. In this paper a new and effective model and analytical simulation method are presented to evaluate dynamic deformation and elastic-plastic stress of reciprocating machine piston rod. This new method has capability to acco...

in order to reduce wear in gudgeon pin, bush and piston boss lubrication is done. oil used in national engine species was 10w40 with dynamic viscosity 5.5 mpa.s at 140 °c (the working temperature). in order to complete investigation the oil film hydrodynamics analysis in small end of connecting rod, a real full model engine with four cylinders has been simulated by avl excite5.1 software. in th...

Introduction Aromatic stacking of π-conjugated planar molecules leads to the exhibition of unique chemical and physical properties. Discotic liquid crystals are, for example, columnar assembly of aromatic compounds with long alkyl chains. Organic electroconductive materials involve alternative charge-transfer stacking of electron-donating and -accepting π-conjugated compounds. Whereas such infi...

Single crystals of the title compound, potassium praseodymium(III) polyphosphate, were obtained by solid-state reaction. The monoclinic non-centrosymmetric structure is isotypic with all other KLn(PO(3))(4) analogues from Ln = La to Er, inclusive. The crystal structure of these long-chain polyphosphates is built up from infinite crenelated polyphosphate chains of corner-sharing PO(4) tetra-hedr...

A new class of infinite coordination polymers (CP) was synthesized using a tetrahedral tetrakis[4-(4'-phenyl-2,2':6',2''-terpyridine)phenyl]methane ligand as an organic node to direct the three-dimensional growth of the network and M(II) (M = Zn, Fe, Ni, and Ru) ions as inorganic linkers, an approach that is the opposite of the metal-as-a-node strategy used in the construction of metal-organic ...
