Then the nanoscale friction can be expected to be reduced if the same system as the above is constructed at nanoscale. This is the initial concept of the present work of superlubricity. Here the combination of the graphene (nanosheet) and the fullerene C_(60) (nanoball) is adopted [Fig. ...
(M D Ellul); durability (A Stevenson and R Campion); design of components, including shear and compression bearings, and vibration and noise control (P M Sheridan, F O James and T S Miller); finite element analysis (R H Finney); and tests and specifications (J G Sommer and Oon Hock ...
- 《Finite Elements in Analysis & Design》 被引量: 53发表: 2010年 Three-Dimensional Finite Element Analysis of High Damping Rubber Bearing A three-dimensional finite element modeling of high damping rubber bearings is studied. At first, the constitutive model of high damping rubber materials p.....
How to set up boundary conditions for longitudinal springs if I use them to represent bearings in Workbench? How to setup the six DOFs in remote displacement for the spring mobile end connected to the vertex on shaft? PS: My shaft was created in a line body in Design Modular and these tw...
Shaft Design Problem Refer the above picture, where a steel shaft is supported by two bearings and a pulley is placed in between the bearings. You have to design the shaft. Weight of the pulley is 1000 N. Input data: Maximum allowable shear stress for the shaft material= 40 Nmm. x Play...
according to different purposes, it is necessary to choice of precision, clearance, keep frame structure, grease and so on, special design of bearing. However, the choice of bearing does not have a certain order, rules, priority should be given to the requirements of the bearings are the...
There are two basic bearing housing designs used in most motors with regreasable rolling element bearings. More motors are manufactured with a same-side design (Figure 2) than a flow-through design (Figure 1). Figure 2 shows the drain plug is the only external path for the grease to exit...
(the design to the bearing is easy to purchase, here is a slight digression, some Koyo cylindrical roller bearing catalog model does have, but some non-standard bearings in mainland China does not have a spot, sometimes futures will for a long time, so in ...
“One of the engineers came out and said, ‘Smell this bearing… they smell different.’ And there we were, sniffing the bearings. “Sure enough, the good bearing and bad bearing smelled different. It was the last thing. We had measured everything, taken pictures—we just hadn’t sniffed...
Wheel bearings are an essential component in the functioning of any vehicle. They bear the weight of the vehicle and facilitate smooth rotation of the wheels. However, choosing the right wheel bearings can be a daunting task for many vehicle owners out t
