As the core control unit of ABS system, ECU plays an important role in evaluating the safety standards of the ABS system, it can be used to control the executive unit according to the state parameters of vehicle. Aimed at the high-cost, complex and long in the road test, an improved ABS ECU test system for the pneumatic ABS is proposed in this paper. Composed of finished ECU, data acquisition card,...
Stress of foundation pile is more sensitive than the other monitoring indexes such as displacement, so it can be observed to show run behavior more efficaciously. Stress components must be separated by influence factors, and stress monitoring model can be built by the relationship of stress components and their influence factors. Wavelet shows good characteristics in time-frequency domain, so it has...
The settlement behavior of pile foundation is an important index for construction and design especially for bridges built on poor hydrologic and geologic conditions. Because the main of Sutong Bridge is situated in the tideway of Yangtze River, the maximum variable load caused by tidal range is about 224MN. It acts on pile foundation circularly, and affects the settlement of the pile group foundation...
Aiming the deficiency of traditional load model used for reliability assessment, this paper proposes a new integrative K-means clustering algorithm incorporating load characteristics information. Based on the clustering algorithm, this model adopts multi-dimension correlation sampling technique considering bus load correlation load forecasting uncertainty to determine the bus load in evaluation period...
