TRANSVERSE VIBRATION TECHNIQUE TO IDENTIFY DETERIORATED WOOD FLOOR SYSTEMS

Transverse Vibration Technique to Identify Deteriorated Wood Floor Systems

Floor System Vibration Control

Experience in the design of steel and concrete floor systems to control vibrations suggests that a floor system’s vibration characteristics are often fundamental to its acceptable performance. In such cases, serviceability drives the design instead of strength. This is particularly true for laboratory floors that support sensitive equipment and floor girders that fall within certain spans. This...

Order analysis of serpentine belt transverse vibration

Transverse vibration of the serpentine belt is effective at noise and durability of it. Therefore, understanding of this phenomenon and studying effective parameters can be used in the process of reducing belt noise and increasing life time. In this paper, transverse vibration of serpentine belt is measured experimentally and analyzed. In the implementation test steps, the displacement of the b...

Conductivity and rupture in crack-deteriorated systems

2014 Experimental results on the conductivity and rupture properties of two-dimensional continuum crack deteriorated model systems are presented. Two different systems are considered. In case 1, cracks are randomly positioned on the bonds of a regular square lattice drawn on the continuous system. Our finite size systems barely reach the critical percolation regime. The results rather correspon...

Wood Density Impact on Hand-Arm Vibration

Nacrtak Despite technological advancements in machinery for timber harvesting, chainsaws are fre­ quently used in forest operations. In Austria 85% of the wood volume harvested (15 million m3) are cut by chainsaws. The two most frequently documented ergonomic threats during motor manual felling include exposure to noise and vibration. This paper presents the results of exposure to hand-arm vibr...
