MODELING OF OPERATING MODES OF VIBRATION AND VIBRATION DAMPING

MACHINES

In previous studies, studies were conducted on the main modes of inertial load during the development of

technological processes of forming blanks of powder materials by the method of vibro-impact pressing.

The design of the model of the inertial vibropress hammer and the description of its parameters makes it

possible to select different pressing modes, to evaluate the effectiveness of their application.

Various mathematical models of the system were used in constructing exact solutions at the stages of

movement between shocks and at the moments of spivudaryan. They were described by linear differential equations

or finite ratios of stereomechanical theory of impact, which were introduced as boundary conditions of the process.

It is advisable to build and analyze a single form of writing the equations of motion for the driving elements of

machines on the entire time axis, which describe the complete set of realizable motions. This is achieved through the

introduction of nonlinear relationships, reflecting the process of force interaction of the collision or their elements.

Key words: vibration machines, vibro-impact machines, hydraulic drive, efficiency, working modes of

pressing, vibro-impact presses
