Abstract

Crank and rod mechanism is the key component of the engine, and its stress variety and load distribution have an important effect on the reliability of the engine. The kinetic and kinematic responses of the crank link mechanism are studied by the coupling analysis of multi-body dynamics and static mechanics, to provide a theoretical basis for design and analysis. Research dynamic response of crankshaft system on the foundation of changing piston and crankshaft as Flesxible body. Analyse dynamic stress regulation of main journal on the basis of flexible and stress response of liquid dynamic pressure bearing all the time.Studies have shown that the pressure of the piston from the top to the piston skirt gradually reduced, the piston pin hole pressure. When the piston of a cylinder produces the impact force, the stress of the crank arm on both sides of the crankshaft increases instantaneously. The bearing oil film pressure is proportional to the change of the journal stress.
