.... Design/methodology/approach The lubrication equations were introduced to calculate the dynamic characteristics of HS-MMJB, and the response analyses of rotor systems were carried out. Experiments were conducted to study the vibration reduction of a rotor system with HS-MMJB. In addition, experiments...

...Jun Sun; Lei Shu; Xianhao Song; Guangsheng Liu; Feng Xu; Enming Miao; Zhihao Xu; Zheng Zhang; Junwei Zhao Purpose – This paper aims to use the crankshaft-bearing system of a four-cylinder internal combustion engine as the studying object, and develop a multi-objective optimization design...

...Li Cui; Yafei He Purpose – The purpose of this paper is to find a new logarithmic profile model of cylindrical roller bearing, which is expected to avoid edge effect and allow a straight portion on the roller considering uniform pressure distribution and easier manufacturing. Design...

...H.Y. Lau; K.P. Liu; P.L. Wong; Wen Wang Purpose The purpose of this paper is to carry out a proof‐of‐concept experiment on positioning control of a smart journal bearing using giant magnetostrictive material (GMM)‐based actuators. Design/methodology/approach In the system, a journal bearing...

...). Design/methodology/approach The dispersion stability of aluminum nanoparticles in liquid paraffin is measured by spectrophotometry, which can be optimization by Taguchi method. The tribological properties are evaluated by using a ball‐on‐ring wear tester. Findings The results show that few...

...Cheng‐Hsien Chen; Yuan Kang; Ding‐Wen Yang; Ren‐Ming Hwang; Shyh‐Shyong Shyr Purpose The purpose of this paper is to study the influence of number of feeding holes on the performance of aerostatic bearings with spindle rotation. In traditional design of aerostatic bearings, the selection of hole...

... restriction parameter for stable operation can be determined for use in the bearing design process. Design/methodology/approach A rigid rotor supported by hybrid oil film bearings with six recesses and capillary‐compensated restrictors is studied. In order to facilitate the calculation of film dynamics...

... with the application of ferrous oxides. Those rings are intended for two‐stroke self‐ignited diesel engines used for driving the diesel locomotives. Design/methodology/approach It was decided to use magnetite, Fe₃O₄, together with a binding agent, sodium metasilicate. Working out the adequate...
