High-frequency breaker vibrator mainly includes three major components of
the structure: the vibration box, knife row and bucket teeth. Due to the periodic
impact load of the high-frequency breaker, there is a risk of failure if the
structure of the exciter is not designed properly, which will seriously affect
the working efficiency and service life of the breaker. The static
characteristic of the exciter is an important part of evaluating the overall
performance of the breaker. It is necessary to do the statics analysis of the
exciter to study the stress distribution and the strain state of the breaker.
Based on the above reasons, the stress analysis and strain analysis of the
finite element modeling of the exciter structure are carried out in this paper.
The simplification and constraint handling of the model are discussed.
