## 30-37 TENDINŢE ACTUALE ÎN CONSTRUCŢIA VAGOANELOR DE MARFĂ ÎN EUROPA

TODAY’S TENDENCY FOT FREIGHT RAILWAY
WAGONS CONSTRUCTION IN EUROPE
Europe has a large railway system used both by passenger trains and
freight trains. On a free open market according with European Regulations a
better new rolling stock can ensure supremacy for train operators. More, the
railway system must compete with other transport systems: road vehicles,
airplanes or ships.

## 19-95 MODIFICAREA STRUCTURII PORTANTE A VAGOANELOR CISTERNĂ ÎN VEDEREA CREŞTERII SARCINII PE OSIE ŞI MICŞORAREA TAREI VEHICULULUI

TANK WAGON BODY CHANGING IN PURPOSE TO
INCREASE AXLE LOAD AND TARE VEHICLE DECREASING
Lifetime of a railway wagon is around 30 year. During that time,
periodical revisions are made. In some cases, the wagon is subject to
modernization programs, which can prolong the lifetime of the wagon to 40
years or more. In some cases the wagon’s owner wish to increase wagonload
capacity in purpose to transport more, because 1 tone of load can increase
exponentially the value of the wagon.

## 23-80 STUDIUL MODELELOR 2D CU AJUTORUL METODEI ELEMENTELOR FINITE

2D MODELS STUDY USING FINITE ELEMENT METHOD
2D models can be used for probe modelling in purpose to perform finite
element analysis in a small time. The 2D model can be the result from a 3D
model.

## 24-9 CENTRUL DE TESTĂRI FEROVIARE FĂUREI AL AUTORITĂŢII FEROVIARE ROMÂNE – AFER SINGURUL POLIGON FEROVIAR DIN SUD-ESTUL EUROPEI

ROMANIAN RAILWAY AUTHORITY AFER’S FĂUREI
RAILWAY TESTING CENTER THE ONLY RAILWAY
FACILITY FROM SOUTH EST OF EUROPE
Romanian Railway Authority AFER is the technical body of Ministry of
Transport in charge with railroad safety. AFER is a complex structure with four
independent bodies: Romanian Railway Safety Authority ASFR, Romanian
Railway Notified Body ONFR, Romanian Railway Investigation Body OIFR and
Romanian Railway Licensing Body. As a part of ONFR there are AFER’s
laboratories and as part of AFER is Railway Testing Center Făurei (CTF
Făurei).

## 24-23 SIMULAREA COMPORTAMENTULUI DINAMIC AL VEHICULELOR FEROVIARE CU AJUTORUL PROGRAMULUI ADAMS/RAIL

RAILWAY VEHICLE DINAMICAL BEHAVIOR
Numerical methods are widely used in purpose to predict the behaviour
of a railway vehicle. Among numerical applications less known are MBS
software.

## 21-92 ÎNCERCĂRILE TENSOMETRICE – CERINŢĂ OBLIGATORIE PENTRU OMOLOGAREA FINALĂ A VAGOANELOR DE MARFĂ

EXPERIMENTAL STRESS ANALYSIS WITH STRAIN
GAGES – MANDATORY REQUIREMENT FOR THE FINAL
HOMOLOGATION OF THE WAGONS
Experimental stress analysis with strain gages is used all over the world
from many years. In Romania we use as testing method from the steam
locomotive age. During the time, the standards were changed and the
measuring devices are more accurate. It is interested to understand why tests
are still necessary during homologation (certification) process.

## 21-91 TRENURILE CU ECARTAMENT VARIABIL O SOLUŢIE DE INTEROPERABILITATE VIABILĂ

VARIABLE GAUGE TRAINS A VIABLE
INTEROPERABILITY SOLUTION
In the last 20 years the Commission has been very active in
restructuring the European rail transport market and strengthening the position
of railways vis-à-vis other transport modes. Commission efforts have
concentrated on three major areas which are all crucial for developing a strong
and competitive rail transport industry: (1) opening of the rail transport market
to competition, (2) improving the interoperability and safety of national networks
and (3) developing rail transport infrastructure 0.

## 21-90 CREŞTEREA SARCINII UTILE A UNUI VAGON CISTERNĂ

The axle load for railway vehicle in Romania is 20 tones. The trend is to
increase the axle load from 20 to 22.5 tones. Because Romania is one of
European Union’s countries for Romanian’s railway vehicle owners it is
important to have modern vehicle able to run all over the Europe. The are many
countries in Europe where axle load is 22.5 tones (Austria, Germany, France
etc.).

## 21-83 ÎNCERCĂRI SPECIFICE DE REZISTENŢĂ LA AMORTIZOARE DE ŞOC DIN POLIETILENĂ

POLYETHYLENE SHOCK ABSORBER STRENGTH
SPECIFIC TESTS
Working on high structures is one of the jobs in the cities vertically
developed. The abilities of climb workers are used in purpose to mount publicity
banners, to clean building face, to mount objects on buildings etc.
The use of fall arrester equipment is made under strictly surveillance
and schooling of the workers because of imminence of the accidents. Before
sailing, the fall arrester equipment are tested and certificated.
