38、le load measurements and the evaluation of asymmetric characteristics of rail vehicles. Part 1 of the standard deals with vehicles operating in normal service, whilst part 2 deals with new and maintained vehicles. Quantities such as vehicle mass and train mass do not depend on the attitude of the su
39、spension (springs) and therefore they are the same when the train is standing as they are when running. The vertical wheel force3) varies with time when the vehicle is in motion and may also be different from one day to another, depending on the state of the suspension. However, as long as the loadi
40、ng of the vehicle does not change, the mean value of the sum of the wheel loads will equal the vehicle mass and is also equal to the sum of the mean wheel loads4). This also applies to axle loads. When the measuring system is installed in a straight track, this also applies to side loads and load di

43、el load and mass of rail vehicles operating (in-service) in Europe. There are two factors that have a profound effect on the integrity of the infrastructure and on rail safety. These are axle over loads, and asymmetric wheel load distributions. This standard provides a framework for the measurement
44、of axle load, and for the evaluation of asymmetric loading. These quantities are obtained whilst the train is in motion in order not to delay its passage. 1 Scope The scope of this European standard is restricted to the measurement of the quasi static or mean wheel and axle loads and the evaluation
45、of the difference in static load between each side of the same vehicle, bogie and wheelset. Other derived quantities covered by the standard are: average axle load of a trainset; vehicle mass; total train mass. The standard is not concerned with the evaluation of dynamic axle or dynamic wheel loads
46、and with the evaluation of wheel condition (i.e. shape, profile, flats). The standard permits the measurements to be made at any speed within the calibrated range, which may be up to line speed. The aim of this standard is to obtain measurement results that give the best possible representative valu
47、es for the load distribution of a running vehicle, which under ideal conditions will be similar to what can be obtained from a standing vehicle. In order to ensure compatibility with EN 14363:2005, which also considers “axle load” as the (varying) sum of the wheel forces, this standard will refer to
48、 these as “quasi-static” quantities. This standard does not impose any restrictions on the types of vehicles that can be monitored, or on which networks or lines the measuring system can be installed. The standard lays down minimum technical requirements and the metrological characteristics of a sys
49、tem for measuring and evaluating a range of vehicle loading parameters. Also defined are accuracy classes for the parameters measured and the procedure for verifying the calibration. The standard contains normative and informative annexes. Annexes denominated as normative are to be considered as integral parts of the standard and the informative annexes are provided for guidance only. It should be noted that the measuring system proposed in this standard sha
