This article presents the analysis and results of analytical, calculation, design solutions for development piston engines aircraft (tractors, automobiles, etc.). The authors propose an original a W-shaped engine with trailer connecting rods made comparative features. main feature is significant reduction in length, and, consequently, length crankshaft. As known, manufacturing internal combusti...

Unbalanced inertia force and moment of crankshaft generated by cylinder pressure have a significant effect on the vibration characteristics diesel engine, but study lubrication balance rate needs to be studied. Based Greenwood-Tripp asperity contact theory average Reynolds equation, an elastohydrodynamic (EHD) model main bearing for V-12 engine is developed, influence different rates analyzed. ...

To explore the actual working characteristic of beating-up mechanism on looms, Step function is adopted to convert resistance an equivalent torque acting rocking shaft, and a new method calculating simulating hereby raised. In accordance with two-state joint clearance, paper establishes double-side model four-bar system in clearance status via ADAMS/View software, under consideration both flexi...
