Ground Vibration Measures for the Rocking Vibration of the Piers with Two-Box Girders Bridge
Earth & Space 2008, 2008 Vibration caused by running vehicles on a highway bridge is spread to the superstructure, substructure s and ground. The ground vibrates both in horizontal and vertical direction. When vehicles load at the tip of the cross beam in the T -shape d pier , rocking vibration of the pier occurs. Its ground vibration in transverse direction is the biggest. In

Negative thermal expansion properties in tetragonal NbPO5 from the first principles studies
AIP Advances, 2017 By using the first-principles calculations based on density functional theory combined with quasi-harmonic approximation, we have studied the geometric structural, thermal properties, and the negative thermal expansion (NTE) properties of tetrahedral ...

Evaluation of Vibration Measurements at Rock Drilling
Acta Montanistica Slovaca, 2004 The paper presents a method for vibration measurements at rotary drilling of andesite, granite and limestone. The measurements were carried out on the drilling stand using diamond-impregnated bits of 46 mm diameter. The vibration signal was monitored by the Microlog CMVA55 at constant input parameters (constant thrust or constant revolutions).

Statistical valuation of vibrations at the rock drilling
Acta Montanistica Slovaca, 2006 The paper describes a measuring device providing a monitoring of forced vibrations arising at the rock cutting by impregnated diamond drilling tools at quasi-constant revolutions and thrust levels. The forced vibrations were measured by a capacity acceleration transducer.
