Research of vibration effect to the operator of feller buncher in the mode of starting from the place

Abstract

In article the model of biodynamic system is developed “the operator
- feller - the packaging car (feller - buncher machine) - an object of
the labor - a tree”. The mathematical description is worked out in the
form of the equation of Lagranzha second number. The system of the
equations is solved concerning elastic deformation suspension seats
of the operator by a method of Runge-Kutta, by engineering math
software MathCAD. Model approbation is carried out on an example
of serially let out feller-packaging cars LP-19A in the dispersal mode
at start-off from the place. As a result of researches it is established:
vibroloading operators of feller-packaging cars exceeds the sanitary
code in 1.8 - 3.6 times. For decrease vibroloading operators it is
expedient to limit accelerations at start-off from the place to 0.4 m/s2.
