ASPECTS WITH REGARD TO THE EFFECTS OF MOTOR VEHICLE ENVIRONMENTAL POLLUTION – A case study
Pollution can be considered a major assault on the environment caused by modern man. Air pollution caused by industrial activities and road traffic has a significant impact on the health of the population, especially on those who are living in urban areas, more exactly for 80% of Europeans. It involves the emanation of organisms, which release harmful substances into the atmosphere. The amount of pollutants emitted into the air we breathe was greatly reduced once the EU has introduced policies and measures addressing air quality in the 1970s. Design and implementation of policies to address this complexity is not an easy task.

TOPOLOGICAL OPTIMIZATION OF THE STRUCTURE IN ENGINEERING

 

Nowadays the rapid development of the industry required use the optimization method. First part of this study shows the structural optimization method used in mechanical enginnering, being made a detailed explanation of the iterative optimization process. In the second part of the paper is presented the CAD modelling and the topological optimization of the holder used in mechanical engineering. the results of the optmization study and the conclusions are presented at the end of this paper.

 

Keywords: topological optimization, finite element analysis, objective functions

Cuvinte cheie: optimizare topologică, analiza cu elemente finite, funcții obiectiv
