aIn fact, to reduce the effect of friction from the control loop in a feed-forward or feed-back configuration the standard proportional-integral-derivative (PID) type control algorithm are already applied. 实际上,减少摩擦的作用从控制回路在一种哺养向前或反馈配置标准比例缺一不可衍生物 (PID) 类型...

This paper aims to simulate the effects of different friction models on tire braking. A truck radial tire (295/80R22.5) was modeled and the model was validated with tire deflection. An exponential decay friction model that considers the effect of sliding velocity on friction coefficients was adopt...
friction. A change in the degree of crystallinity of the polymer matrix is determined on the basis of the XRD data. Comparison of the diffraction patterns recorded at symmetric scan mode and in the grazing-incidence geometry showed a difference in the structures of the surface layers and sample...
Single-pass friction stir processing (FSP) was used to increase the mechanical properties of a cast Mg-Zn-Zr-rare earth (RE) alloy, Elektron 21. A fine grain size was achieved through intense plastic deformation and the control of heat input during processing. The effects of processing and ...

The test results indicated that the mobilized horizontal effective stress regime that controls pile side friction primarily depends on the in situ sand state, as reflected by the cone penetration test (CPT)qcresistance. A zone of highly stressed sand that produced a concentration of high shear ...
An analytical solution was obtained to evaluate the effect of friction on flow distribution in both dividing and combining flow manifolds. The governing equation follows the derivation given by Bajura (1971). A constant cross-sectional area of the manifold header and a constant friction factor along...
used to overcome the frictional effects. The only exception occurs in downwardly inclined sections of pipe where elevation effects may overcome the pressure-decreasing effects of friction. The faster the fluid travels in the pipe, the greater the frictional stresses and the greater the pressure ...
aHowever, the end effect of the flow friction in a Pelton turbine results into the reduction of the system efficiency and the power output. 然而,flow摩擦的边缘效应在Pelton涡轮结果到系统efficiency和功率输出的减少里。[translate]
