...Qiyin Lin; Nan Yang; Jun Hong; Lian Liu; Yuhan Zhang Material stiffness, a significant parameter of a contact interface, is investigated to improve the uniformity of the contact pressure. A contact interface material stiffness optimization design algorithm is developed based on the modified solid...

... the highest sound pressure with a single dominant frequency. This difference is attributed to the high contact pressure and severe wear on the surface of the hexagonal friction block. Differences in the installation angle of the triangular/hexagonal friction blocks affect wear debris behavior, distribution...

.... Assoc. Editor: Dae-Eun Kim. 20 05 2013 08 12 2013 The application of advanced high-strength steels (AHSS) generally makes it necessary to use higher tool-sheet contact pressures compared with those used for forming low-strength steel, and it leads to significant changes...

... 110.26 °C). Therefore, considering the pressure distribution influence, it may be assumed that the complete contact areas were lubricated with liquid oil. Moreover, the maximum contact pressure of 1.5 GPa imposed within Case C corresponds to an extrapolation position in Eq. (50 c ) . Consequently...

...Xinghui Han; Lin Hua After obtaining the detailed information about the contact pressure and slip distance response predicted in the FE simulation, the wear response over the surfaces of the ring workpiece can be achieved accordingly based on Eq. (10) . However, as described above...

... of the detecting gas and the signal of the gas chromatograph was calibrated prior to the experiments ( 9 ). The leakage test was carried out at each contact pressure to measure the amount of leakage. The polymer film method is used to measure the real contact area between two solid surfaces by insertion...

... interface to an ultrasonic wave can be modeled as a spring. If the contact pressure is high the interface is very stiff, with few air gaps, and allows the transmission of an ultrasonic sound wave. If the pressure is low, interfacial stiffness is lower and almost all the ultrasound is reflected...
