An Improved Optimal Slip Ratio Prediction considering Tyre Inflation Pressure Changes [PDF]
The prediction of optimal slip ratio is crucial to vehicle control systems. Many studies have verified there is a definitive impact of tyre pressure change on the optimal slip ratio.

The existing control methods for the slip rate of the driving wheel of a test prototype have limitations that cause low-quality tillage and finishing operations. We propose a slip rate control method based on the dual factor adjustment of wheel speed and

Practical issues in slip-resistant bolted connections for steel structures [PDF]
The application of slip-resistant bolted connections is necessary to prevent the contribution of slippage due to bolt-hole-diameter clearances in the lateral displacements of high-rise steel-braced frames or other high-rise structures.

Implications of a 20-Hz Booster cycle-rate for Slip-stacking [PDF]
We examine the potential impacts to slip-stacking from a change of the Booster cycle-rate from 15- to 20-Hz. We find that changing the Booster cycle-rate to 20-Hz would greatly increase the slip-stacking bucket area, while potentially requiring greater ...

Development of a 1-D Performance Prediction Model for Pumps as Turbines
Pumps as turbines (PaTs) are becoming more and more attractive in Small Hydropower. PaTs are considered a cost-effective alternative to conventional turbines as long as their turbine characteristic curves can be predicted. Indeed, manufacturers need of a

Stick-slip and Torsional Friction Factors in Inclined Wellbores [PDF]
Stick slip is usually considered a phenomenon of bit-rock interaction, but is also often observed in the field with the bit off bottom. In this paper we present a distributed model of a drill string with an along-string Coulomb stiction to investigate the effect of borehole inclination and borehole friction on the incidence of stick-slip. This model is

The sliding-contact factor (ηsc): a novel index for slip risk definition
The causes of slip are multiple and depend on the mechanical and aesthetic characteristics of the surfaces in contact, and on external elements related to the specific situation. The non-slip characteristics of a surface can be evaluated by measuring the
