Final Design Review: Wear Test Machine, Justin Ju-Han Hou, Abraham Jack Mitchell, Alexandra Denae Pavano, Jahyun Kaylla Son
Mechanical Engineering
A California Polytechnic State University Senior Project team has been tasked by Marvin Engineering Co. to design and build a friction wear test fixture; the fixture is to characterize the coefficient of friction and potential friction wear of various industry adopted metal pairings in an oxygen-free environment. This final design review serves to document project research, full design process, method of operation of final product, and a comprehensive testing procedure.
The R&D department at Marvin Engineering Co. proposed this investigation in order to explore the phenomenon of friction and adhesive wear, specifically the occurrence of galling between stainless steel surfaces. …
Transient Thermomechanical Interactions Of Shaft-Bushing Pair In Bearings - A Finite Element Study, Rajesh Krithivasan
Transient Thermomechanical Interactions Of Shaft-Bushing Pair In Bearings - A Finite Element Study, Rajesh Krithivasan
LSU Master's Theses
This thesis presents a finite element parametric study of the transient thermomechanical interactions of shaft-bushing pairs in bearings to gain insight into the nature of two categories of failures encountered in practice. The first type of failure deals with occurrence of the so-called thermally induced seizure (TIS) during the start-up period followed by an investigation of TIS due to a transient flow-disturbance. The second part deals with the thermomechanical interactions of pin-bushing assembly under heavy oscillating loads where the failure is by TIS and/or thermal galling. An extensive set of parametric simulations covering a wide range of loads, speeds, operating …
