This is the main reason why many of the existing rigs simulate track with the disc, roller or ring.
Nonetheless, in many investigations, linearized orpartially linearized kinematic expressions are used to define thecreepages. Spoorenberg RC, Snijder HH, Hoenderkamp JCD 2011 Finite element simulations of residual stresses in roller bent wide flange sections. shows the newly-built setup, established on a firm fundament in the laboratory. 2 This scaling strategy keeps the stress and strain in materials the same as reality.
Three alternatives within this category are defined as shown in Fig. J Sound Vib 330 22 :5309—5321• Such term has also been used for the same purpose by other researchers; see e. Consequently, an optimum mechanism is achieved through technical evaluations and synthesis of the structures, characteristics and performance. Proc Inst Mech Eng, Part F: J Rail Rapid Transit 226 2 :124—139• This means that for the purpose of high-frequency dynamic investigation in the wheel—rail contact, it is not essential to include the vehicle or bogies with their complex configurations into the testing procedure.
ballast track, slab track, embedded track with including their real material nonlinearities. The modelling procedure with FEM and its validation against Hertz and Kalker solutions were previously reported in .
Although detailed models of the wheel—rail contact and damages, as well as vehicle—track interaction have been developed, further field characterization and experimental verifications are needed to better understand the root causes of the RCF.
Struct Control Health Monit 24 2 :1848• Due to the same reason, the majority of the existing test rigs in the literature have used the curved track principle.
Such loading mechanism can be suitable for quasi-static analysis of the wheel-rail contact problem, while the loading mechanism of Alt-1 better represents the dynamic nature of the system.
The components of the scaled track system were designed and made with the specifications given in Table.
The testing procedures for fatigue testing of metals are fairly established in terms of methodologies, instruments and the applications.
