Classical approach to determining the natural frequency of continual subsystem of three-mass inter-resonant vibratory machine

Problem statement. The three-mass vibratory system can be defined by five basic parameters: inertial parameters of the masses and stiffness parameters of two spring sets. Unlike the classical discrete system, the discrete-and-continual one consists of two rigid bodies connected by one spring set that form the discrete subsystem, and of the reactive mass considered as deformable (elastic) body characterized by certain stiffness and inertial parameters, which are related with one another.

DYNAMIC ANALYSIS OF CARS OF ROLLER FORMATION TAKING INTO ACCOUNT DISSIPATIVE PROPERTIES OF DRIVING MECHANISMS

Aim. Definition of loadings in elements of roller forming installations with different driving mechanisms taking into account rigidity and coefficient of dissipation of the transmission gear. Method. Roller forming installations with the recovery driving mechanism on two forming carts, energetically balanced driving mechanism on three forming carts and the balanced driving mechanism on four forming carts are chosen as an object of researches.
