Overdrive characteristics based fault tolerant control method for active steering bogie with switchable control structure

Shiqiao Tian, Huailong Shi, Lai Wei, Huanyun Dai et autres

The primary work of this study is the implementation of active fault-tolerant control (FTC) following actuator failure, utilizing the overdrive characteristics of active steering bogies. A switchable control structure, designed based on these overdrive characteristics, is proposed and demonstrated to provide robust …

Comparison of evaluation methods for the dynamic characteristics of railway hydraulic dampers

Caihong Huang, Min Shi, Jing Zeng

The EN and Area methods are commonly reported procedures for evaluating dynamic damper characteristics, both predominantly relying on time-domain data of damper force and displacement, with the EN method established as a standard in EN13802. However, these time-domain approaches do not fully …

Stability assessment of railway vehicles considering undefined nonlinearity in static force–velocity characteristics of hydraulic yaw dampers

Caihong Huang, Yunguang Ye, Jing Zeng, Chunyuan Song

Yaw dampers are usually tuned according to the nominal static force–velocity (F–V) characteristics specified by the vehicle manufacturer. However, in the low-speed region, the static F–V curve often varies significantly among damper suppliers due to a lack of standardised specifications. This variability …

Carbody swaying suppression for a high-speed rail vehicle by utilising active lateral suspension control

Huailong Shi, Jing Zeng, Liang Duan

This study proposes the use of active lateral secondary suspension (ALS) to address low-frequency carbody swaying in high-speed rail vehicles under low wheel-rail conicity conditions. Field experiments reveal lateral acceleration exceeding 0.10 g at a dominant frequency of 1.4 Hz, with a …
