Changing behavior of friction coefficient for high strength bolts during repeated tightening
, 2020Due to its strength advantage, high strength bolts are able to provide larger clamping force. However, the changing behavior of friction coefficient during repeated tightening will adversely affect the tightening torque - clamping force relationship.

Robust Estimation of Road Frictional Coefficient
IEEE Transactions on Control Systems Technology, 2011Vehicle active safety systems stabilize the vehicle by controlling tire forces. They work well only when the commanded tire forces are within the friction limit. Therefore, knowledge of the tire/road friction is important to improve the performance of vehicle active safety systems.
