friction coefficient; while the intensity of heat transfer at cooling stage has lower effect on stress distribution. Key words: friction coefficient; transient heat transfer; stress field; distortion... shaft shoulder are the large tightening torque and too large static friction coefficient. SNIEZEK et al [9] showed that producing a geometric de-phasing treatment on the shaft and the bore has......
. Then, according to the constitutive relation in Fig.2, the mathematical expression of the hysteresis dry friction could be derived as (5) where μ is the friction coefficient between...J. Cent. South Univ. Technol. (2011) 18: 679-684 DOI: 10.1007/s11771-011-0747-x Forced response characteristics of bladed disks with mistuning non-linear friction WANG Ai-lun(王艾伦)1, 2, LONG Qing......
. The reason is that there are too skidding pavements. The problems were discussed here from the tribological aspect. 1 Adhesion coefficient To sure the car travel safely on road, enough friction... E=300-400 MPa, Poisson ratio), tangent stress is: (13) When the radial loading and normal reaction force are equal, , adhesion coefficient equals the static friction coefficient......

lubrication, the influence of parameters of surface texture and operation conditions on friction coefficient was studied by solving lubrication computation model of surface texture. The results show... of friction coefficient and the influence of depth and diameter on friction coefficient is studied separately, but when the aspect ratio lies in 0.005 to 0.01, the corresponding friction coefficient......
is the microdamping of the elastic bristles; σ2 is the viscous friction coefficient; g(v) is a nonlinear function describing a characteristic of the Coulomb friction and the Stribeck effect. Its value lies... friction force; Fcis the Coulomb friction force; vs is the Stribeck velocity coefficient which determines how quickly g(v) approaches Fc; α is the appropriate fitting parameter. For constant velocity......
