| description | The paper analyzes the dynamic dependencies between
the impact force and the depth of the indenter penetration
into the obstacle. The indenter is a hardened steel ball.
The target is made in the form of a rod from various
types of steel, duralumin, aluminum and lead. As a result
of digitizing the graphs of dependencies, interpolation
formulas are obtained for different phases of the impact
(the first phase of the impact is compression; the second
phase of the impact is unloading). In the course of the
analysis of interpolation formulas, absolute and relative
data on the transformation of the initial kinetic energy
of the indenter into the distribution of energies after
impact are obtained: the value of the kinetic energy of
the indenter after the impact, the values of the energy of
elastic and plastic deformations, and the energy of shock
waves.
The results obtained can be used to design impact
machines with an indenter impact speed against an
obstacle up to 100 m/s. |
