A Method for Setting Wagon Speed Restrictions Based on Wagon Responses
MetadataShow full item record
This article presents a method to set wagon speed restrictions based on wagon body accelerations. For the specific locomotive, wagon conditions and track states, an individual wagon critical speed may be determined from its running stability. Furthermore, stability can be evaluated by a wheelset derailment index, which is determined by the ratio of lateral and vertical wheel-rail contact forces. Providing theinformation on the critical speed online has, without doubt, significant industrial application potentials.The research efforts in this article are focused on the estimation of wheel-rail contact forces usingmeasured wagon body accelerations.

Grey box-based inverse wagon model to predict wheel-rail contact forces from measured wagon body responsesXia, F.; Cole, C.; Wolfs, Peter (2008)A grey box-based inverse wagon model was developed to estimate wheel-rail contact forces using only measurements of wagon body responses as inputs. The project is based on a similar application using a deterministic inverse ...
Wolfs, Peter; Bleakly, S.; Senini, S.; Thomas, P. (2006)In the case of a railway wagon running on track, irregularities in the track formation can lead to complex dynamic interactions. Experience has shown that track geometry alone is not a good predictor of vehicle response ...
