The resistance encountered by the active organ – the bucket – of the loader when digging into the material pile is part of the category of external influences applied to the equipment. Generally this force is not constant ...

Forging hammers cause very high vibration levels, so vibration control is advisablein nearly all cases. For this reason, in present exist recearch with the object of to decrease and eliminate the shocks and vibration ...

This paper presents a dynamical analyze on the foundation of machine when are apply stresses such the beat (percussion). In this way can be evaluate dynamical response of the structure, in our case foundation of machines, ...

The artificial compacting of the soil is made mostly with machines with dynamical action such as vibrating plate, vibrating beater or vibrating drum. Their effect on the compacting process of the soil has two origins: the ...

The aim of the work presented here was to investigate the possibility of using hangs in the non-linear vibration characteristics to detect damage in mechanical structure. The nonlinearities were detected by examining the ...

Some bridges located in areas of high seismic risk have the decks supported through simple pendulum what dissipates energy by dry friction. The friction force that occurs by motion of the two surfaces is dependent on both ...

This paper presents a dynamical analyze on the foundation of machine when are apply stresses such the beat (percussion) in nonlinear behavior of the viscous-elastic elements hypothesis. In this way can be evaluate (more ...

This paper presents constructional solution adoption draftworking gear, loader IC 04, assure existence every tyre, reaction non-vanishing. The evidence profitability solution suspension draft.

In the analysis of dynamic processes and plastic deformation which appear on the forging and die forging equipments dint the shocks (forging hammers and screw presses), it is use frequently theoretical study of de collision ...

This paper analyzes, on the theoretical level, the dynamic response of a viaduct section, dynamically isolated by systems with a selective type of links with viscoelastic and with dry friction. Evaluation of kinematic ...
