Abstract
The questions of the impact design factors of the many-mass mechanical system to the oscillating
force process during transient regimes of the hoist mechanism jib mobile crane operation are considered.
The study with numerical methods with mathematic model describing transient regimes,
appearing in the hoist mechanism drive of the automobile crane, with combustion engine equipped
was conducted. The four-mass dynamic model for estimation of the impact of different factors to
the dynamic loads was built. This model has identical ink margin as original. The realization this
model with numerical Runge-Kutta method is done.
Dynamic load of the system with comparative analysis of force of drive mass graphics
method was estimated. Conducted research showed that in basic the amplitude-frequency
characteristic of oscillating process with accelerative-elastic parameters of the system is estimated.
It is necessary to attend for accelerative-elastic parameters of the system during design for exclusion
such negative effects as resonance and jumping.
