... a maximum relative difference of less than 3.2% to the numerical simulation results, proving its efficacy. This curve is particularly beneficial for multibody-dynamics models, providing a reliable tool for predicting frictional forces in systems where elliptical EHL contacts, operating within the PE regime...

...Hui Zhuang; Jianguo Ding; Peng Chen; Yu Chang; Xiaoyun Zeng; Xingbao Liu The damped mass-spring model is often used for the dynamic modeling and vibration analysis of aerostatic bearing systems by taking the air film as equivalent springs, especially when the bearing is used as a key component...

... on active piezoelectric restrictors, including the amplitude frequency and phase-frequency characteristics, are analyzed theoretically and experimentally. In the analysis, the influence of the pipeline model on the system characteristics is studied. Then, the feasibility and effectiveness of the active...

...Mohsen Nakhaeinejad; Michael D. Bryant Multibody dynamics of healthy and faulty rolling element bearings were modeled using vector bond graphs. A 33 degree of freedom (DOF) model was constructed for a bearing with nine balls and two rings (11 elements). The developed model can be extended...

...Katsuhiro Ashihara; Hiromu Hashimoto In designing of engine bearings for automobiles, we need to establish a mixed lubrication model that considers the solid-to-solid contact between journal surfaces and bearing surfaces with microgroove. However, as far as we know, there is no literature treating...

... conditions. To resolve this problem, the author suggests a combined approach: shorthand experimental researches and mathematical modeling of erosion wear. The suggested model, used for defining the mass loss of the working element affected by solid particles in the slurry, offers the possibility...

...L. J. Yang A new equation has been formulated and found successful for modeling the wear rate of test specimens. It is capable of predicting the standard steady-state wear rate and the net steady-state wear rate with a F A value, an exponential function, of 0.99 and 0.999, respectively...
