Effect of Loading Condition on Traction Coefficient Between Shoes and Artificial Turf Surfaces [PDF]
Background. The interaction between a shoe and a turf surface is highly complex and difficult to characterize. Over the three decades since artificial turf was introduced, researchers have attempted to understand the traction caused by the interaction ...

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Smart Traction Control Systems for Electric Vehicles Using Acoustic Road-type Estimation
The application of traction control systems (TCS) for electric vehicles (EV) has great potential due to easy implementation of torque control with direct-drive motors. However, the control system usually requires road-tire friction and slip-ratio values,

Research on Traction System for Variable Marshalling EMU at Speed 250-350 km/h
The performance index of the 250-350 km/h programmable EMU traction system was introduced. The formula for calculating total basic resistance of the EMUs (Electric Multiple Units) was determined by using the integrated Datong-Xi'an high-speed railway ...
