Description
Technical field
The invention belongs to detection technique field, relate to a kind of train detection equipment, from dynamic detection system and method inside especially a kind of Railway wheelset；This detection system can to inside Railway wheelset from carry out efficient, dynamic, accurately detect, and carry out necessity detection data statistic analysis and prediction, to improve the safety coefficient of train operation.
Background technology
From the horizontal range referring to two wheel rim inner side plane on same Railway wheelset inside Railway wheelset.Whether can pass through in train driving process and have direct relation from Parameters variation inside track switch, whether safe and stable operation and wheel, inner side is one of size of strict regulations in Railway wheelset standard geometric parameter from Parameters variation.According to standard specify, inside China's Railway wheelset from utilization limit be generally 1353 ± 3mm.
Along with the demand for development that Chinese Railway is built, in guarantee driving safety even running, accelerate the aspects such as train speed raising and realize important breakthrough, inside train, be to ensure that one of key factor of driving stationarity and circuit steadiness from the Proper Match with gauge.In train operation, edge can be subject to the effect of cross force by wheel, causes that distance between backs of wheel flanges becomes big after running a period of time or diminishes, it is therefore desirable to each Train Wheel is carried out periodic detection.Detection parameter exceedes Railway wheelset needs of regulation service limits repair and even scrap process, thus the potential safety hazard eliminated in train driving process ensures train smooth operation.
