Relative movements take place at the chain joint between pin and bush, which lead to wear of the chain joint due to friction and so to chain elongation. The chain joint is generally lubricated with oils, through which elastohydrodynamic processes can occur in the gap between the pin and the bush of the chain joint. A simulation model is developed here to examine these elastohydrodynamic processes considering a mass conserving cavitation model, the Newtonian flow behaviour of the lubricant and the structuring of the bush surface, whereby the real form of the bush is considered. MBS simulations are used to obtain realistic loads on the chain joint."}],"type":"journal_article","publication":"Tribology International"},{"year":"2018","intvolume":"       118","page":"442-450","citation":{"ama":"Thielen S, Magyar B, Sauer B, et al.

A twist structure on the surface can cause pumping of the fluid during shaft rotation which can result in leakage. In this paper a special, new turning method, which consists of at least two turning steps with feed in reciprocal direction, is presented as an alternative to the conventional manufacturing process. The goal is to create a surface structure with a net pumping rate of zero. Shafts turned with the new proposed method are compared to turned shafts from previous investigations [1]. Criteria for the comparison are the surface pumping rate, leakage and wear behavior of the surface."}],"status":"public","publication":"Tribology International","type":"journal_article","keyword":["Radial shaft seals","Turned surfaces","Microstructure"],"extern":"1","language":[{"iso":"eng"}],"_id":"34438","department":[{"_id":"146"}],"user_id":"38077"},{"publication":"Tribology International","type":"journal_article","abstract":[{"lang":"eng","text":"A method for the reconstruction of turned shaft surfaces with a (fractal) Weierstrass–Mandelbrot-function (WMF) is presented. The WMF is modified to allow to freely choose a phase-shift for every frequency. The reconstruction is based on distinct profiles in axial and tangential direction and the statistical distribution of low-wavelength portions of the surface is taken into account by adding t-distributed random deviations to the surface. The work is validated by reconstructing measured shaft surfaces with different manufacturing parameters, which shows good accuracy for periodic surfaces. This method allows for a characterization of surfaces with a limited number of parameters and can be used to store the characteristics of measured surfaces with a reduced amount of data compared to a point-cloud surface."}],"status":"public","_id":"34439","department":[{"_id":"146"}],"user_id":"38077","keyword":["Roughness","Structure","Fractal","Machining"],"extern":"1","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0301-679X"]},"year":"2016","page":"349-357","intvolume":"        95","citation":{"apa":"Thielen, S., Magyar, B., &#38; Piros, A.
