Analysis of Static Characteristic of Hydrodynamic Bearing with Different Surface Roughnesses
Jixie chuandong, 2020 When the working surface roughness of hydrodynamic sliding bearing reaches the same magnitude （micron） as the oil film thickness， the influence of surface roughness on the characteristic parameters of bearing cannot be ignored.

Experimental Study of Reciprocating Friction between Rape Stalk and Bionic Nonsmooth Surface Units
Applied Bionics and Biomechanics, 2015 Background. China is the largest producer of rape oilseed in the world; however, the mechanization level of rape harvest is relatively low, because rape materials easily adhere to the cleaning screens of combine harvesters, resulting in significant ...

Advanced Engineering Materials, EarlyView.Cladding is a proven method that boosts the surface qualities of mechanical parts by applying a layer of more durable material over a base substrate. This work responds to the needs of offshore and pressure vessels sectors by focusing on cladding a super austenitic steel onto low‐carbon steel through gas tungsten arc welding.

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam
Advanced Engineering Materials, EarlyView.Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...
