Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 4, doi: 10.1007/s11783-018-1073-4

Abstract:

An-RBC reactor is highly suited to treat metallic wastewater.

Metal removal is due to sulfide precipitation via sulfate reduction by SRB.

Cu(II) removal was the best among the different heavy metals.

Maximum metal removal is achieved at low metal loading condition.

Metal removal matched well with the solubility product values of respective metal sulfide salts.

The prediction technology study of fatigue life for key parts of a tracked vehicle’s suspension system

WANG Hongyan, RUI Qiang, HE Xiaojun

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 1,   Pages 68-71 doi: 10.1007/s11465-007-0011-0

Abstract: In allusion to fatigue life of a tracked vehicle torsion bar, a virtual prototype model of the tracked vehicle suspension system including a flexible torsion bar was built based on dynamic simulation software ADAMS. Node force and stress results of the torsion bar from last step simulation were acquired; taking into account the material characteristics and influential factors, fatigue life of the flexible body of the torsion bar was predicted. Engineering results can be acquired through the contrast of the result of virtual test and statistical fatigue.
