Railway Vehicle and Track Interaction Testing Center
Postal car model 61-906
In March 2009, "Test Center crew interaction and ways of Railways held a dynamic way, and on the impact of the road and turnouts test mail wagon model 61-906 manufactured by OAO Torzhoksky Carriage Works" under the contract Registry certification at the federal railways (RS FZHT ).
The tests were carried out in straight line sections in line Saint Petersburg - Moscow, with speeds up to 160 km / h in the curves of radius 389 m (1 km section of Gateway-Vinokoly) and 645 m (38-km section Likhoslavl Vyazma) and the slip translation-type P65 grade 1 / 11 (turnout № 50 Art. Torzhok).
Normalized performance had the car and its impact on the path determined according to the "Library of VT CL 01-98. Cars, passenger rail. Requirements for certification."
During the test we measured the following indicators of interaction of the crew and the ways: frame strength, the coefficients of vertical dynamics, vertical and lateral forces transmitted from the wheels on the rails, the vertical and lateral forces acting on the rail on the lining stresses in the edges of the foot rails, moving the outer rails threads in curves (squeezing heads and drawdown).
For the calibration of measuring systems used force sensors U2, and C3 production company HBM, Germany.
Status of the way to the experimental plots and turnouts determined by sets of geometric parameters, provided the requirements of CP-774 "Instruction on the current contents of the track and CP-515" Instruction to transcribe tapes and assess the state of the track on the testimony of puteizmeritelnogo car CSRI-2 and measures to ensure traffic safety, CRB-393 "Instruction on the maintenance and operation of facilities and equipment, rolling stock and traffic circulation in areas of high-speed passenger trains and to satisfy the requirements of these Instructions for the velocities, which are conducted by experienced travel.
The total number of measurement channels on the wagon and plots the path was over 150. The results obtained allowed under the current regulatory documents on the basis of the experiment and additional calculations to determine performance indicators and the impact on the way and turnouts experienced postal wagon.
