dcterms:description
One of the most important problem of coal mining by bucket wheel excavators is how to minimize influence of vibrations on driver´s body. Experimental and numerical research was aimed to vibrations suppression and a new cab and seat mounting of wheel excavator was designed. A suitable possibilities of cab suspensions were investigated to minimize driver body vibrations and to decrease influence of mining process to drivers health. After optimization one concept was chosen. A new methodic of measured data evaluation was created for using in excavators as well as in laboratory. The new concept of dynamic seat absorber were designed also. To investigate the spatial vibrations suppression, an experimental device has been used – a platform with six degrees of freedom which enables measured signal realization in laboratory. Displacements, velocities and accelerations of the series of points on a driver body were determined by optical measuring technique - by dynamic measuring system PONTOS. The signal recorded before and after optimization were used and the effect on the driver body response was evaluated.
