Contacting directly with road within postcard size of contact area, it is mounted and guided by the suspension system. Therefore kinematics and compliances of suspension system greatly influence the frictional coupling of tire tread elements and road surface asperities by affecting pressure and sliding velocity distribution in the contact zone. This study emphasizes the development of a numerical methodology for frictional rolling contact analysis with focus on interaction of suspension system dynamics and tire-road contact using ADAMS. For this purpose a comprehensive flexible multibody system of the multi-link rear suspension is established, where both flexible and rigid bodies are modeled to allow large displacements with included elastic effects. To meet accuracy requirements for the high frequency applications, such as road excitations, the amplitude- and frequency-dependency of rubber-metal bushings is included. Furthermore the proposed flexible viscoelastic suspension model is enhanced by a Flexible Ring Tire Model (FTire), which describes a 3D tire dynamic response and covers any road excitations by tread submodel connected to road surface model. Concerning the verification and validation procedure numerous experiments are carried out to confirm the validity and the accuracy of both the developed submodels and the entire model. The devised approach makes it possible to investigate the influence of suspension system design on dynamical rolling contact and to evaluate tire tread wear. Therefore it can be a useful tool to predict frictional power distribution within the contact area under more realistic conditions.","lang":"eng"}],"status":"public","_id":"9963","user_id":"55222","department":[{"_id":"151"}],"keyword":["Kinematics and compliances","flexible viscoelastic suspension model","frictional rolling contact analysis","frictional power distribution."],"language":[{"iso":"eng"}]},{"date_created":"2021-05-04T08:47:31Z","author":[{"first_name":"Steffen","last_name":"Jesinghausen","orcid":"https://orcid.org/0000-0003-2611-5298","id":"3959","full_name":"Jesinghausen, Steffen"},{"first_name":"Rene","full_name":"Weiffen, Rene","last_name":"Weiffen"},{"full_name":"Schmid, Hans-Joachim","id":"464","last_name":"Schmid","first_name":"Hans-Joachim"}],"date_updated":"2023-01-17T07:37:53Z","main_file_link":[{"url":"https://link.springer.com/article/10.1007/s00348-016-2241-6"}],"doi":"10.1007/s00348-016-2241-6","title":"Direct measurement of wall slip and slip layer thickness of non-Brownian hard-sphere suspensions in rectangular channel flows","publication_status":"published","publication_identifier":{"issn":["0723-4864","1432-1114"]},"quality_controlled":"1","citation":{"ieee":"S.

Nevertheless, the origin and the evolution are not completely clear yet. Regarding suspensions, the effect becomes even more complicated, because different mechanisms like pure slip or slip due to particle migration have to be taken into account. Furthermore, suspensions themselves show many flow anomalies and the isolation of slip is complicated. In order to develop working physical models, further insight is necessary. In this work, we measured experimentally the wall slip velocities of different highly filled suspensions in a rectangular slit die directly with respect to the particle concentration and the particle size. The slip velocities were obtained using a particle image velocimetry (PIV) system. The suspensions consisting of a castor oil–cinnamon oil blend and PMMA particles were matched in terms of refractive indexes to appear transparent. Hereby, possible optical path lengths larger than 15 mm were achieved. The slip velocities were found to be in a quadratic relation to the wall shear stress. Furthermore, the overall flow rate as well as the particle concentration has a direct influence on the slip. Concerning the shear stress, there seem to be two regions of slip with different physical characteristics. Furthermore, we estimated the slip layer thickness directly from the velocity profiles and propose a new interpretation. The PIV technique is used to investigate the viscosity and implicit the concentration profile in the slit die. It is shown that the particle migration process is quite fast.","lang":"eng"}]}]
