ANALYSIS OF TRAFFIC NOISE FROM A MAIN ROAD CROSSING A CITY
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2018, Vol 63, Issue 1
Abstract
The impact of road traffic on the environment is practically determined by a calculation procedure. Reliable calculation results require reliable sources determination. The theme of this study was to prepare the noise map of the area traversed by a major road, inside a neighbourhood which is part of an urban agglomeration, and to assess the effect of the noise on the population. No input data was available, so all the necessary data was collected on site, or taken from free available sources. The paper presents the sources of map data, the methods used to collect and process road traffic data, and the methods and tools used to process the outputs. Beside the noise mapping software, are used GPS, GIS and CAD techniques.

ON THE DYNAMIC BEHAVIOR OF ELASTIC FRAME STRUCTURES WITH BASE IMPOSED HARMONIC DISPLACEMENT
The dynamic response of an elastic shear frame structure to imposed lateral harmonic displacement of the base slab is analyzed within frequency ranges placed below and above natural frequencies. It is shown that between...
ON THE SOFT ROBOTICS CONSTITUTIVE LAWS
Soft robotics is a class of hard and soft robots that contain a rigid internal structure and nonrigid body parts. The elastic components consist of nanostructured materials which exhibit new features such as the echoes r...
COUPLED TRANSVERSAL AND LONGITUDINAL VIBRATIONS OF A PLANE MECHANICAL SYSTEM WITH TWO IDENTICAL BEAMS
The paper aims to highlight some vibrations properties for a plane beams structure, where transverse vibrations are coupled with the longitudinal vibrations. In engineering practice it often happens that identical parts...
