Process improvement in laser hot wire cladding for martensitic stainless steel based on the Taguchi method

Zilin HUANG,Gang WANG,Shaopeng WEI,Changhong LI,Yiming RONG

Frontiers of Mechanical Engineering 2016, Volume 11, Issue 3, Pages 242-249 doi: 10.1007/s11465-016-0397-7

Abstract:

Laser hot wire cladding, with the prominent features of low heat input, high energy efficiency, andThe cladding process, however, needs to be improved by using a quantitative method.volumetric defect ratio was proposed as the criterion to describe the integrity of forming quality for claddingMetallurgic observation of cladding layer was conducted to compare the forming quality and to validate

Wind tunnel test study on the wind pressure coefficient of claddings of high-rise buildings

Yong QUAN, Yi LIANG, Fei WANG, Ming GU

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 4, Pages 518-524 doi: 10.1007/s11709-011-0128-4

Abstract: The area-averaged most unfavorable wind pressure coefficients (MUWPCs) on various regions of building surfaces and the influence of the side ratio and the terrain category were studied based on wind tunnel test data of scale models of typical high-rise buildings with rectangular cross-sections. The negative area-averaged MUWPCs in the middle-height edge areas generally increased with an increasing / side ratio. The area-averaged MUWPCs can be well fitted with a function of the average area reduced by the square of the building depth, . In addition, no unique pattern was found for the effect of the terrain category on the MUWPCs.
