Dynamical Analyses of Piston Machines Used in Oil Industry

The investigation of a complex problems with taking into account of a friction, oscillation and impact processes in mechanisms of piston machines, does possible the all-round decision of the problem of increase of their reliability and durability. In this work, based on the dynamic analysis of the crank-piston mechanisms the method for definition of the parameters of longitudinal vibration of a connecting rod of piston machines is developed. The dangerous sections of a “floating” connecting rod are determined.
