Coupling Analysis of Turbocharger Compressor Blade Vibration and Blade Profile Optimization
2021 IEEE International Conference on Electrical Engineering and Mechatronics Technology (ICEEMT), 2021The optimization of the turbocharger structure can significantly improve its properties. In order to establish the dynamic coupling formula, the blade was simplified as a thin flexible rectangular plate moving in space, and the Lagrange dynamic equation was used to solve the problem.

Transportation Research Record: Journal of the Transportation Research Board, 2011
The first attempt to develop and implement an optimization module to minimize agency costs and vehicle operating costs in the Western Cape, South Africa, was considered unsuccessful. Routines incorporated the current roughness of the road; deterioration as a result of traffic, climate, and materials; and improvement in roughness after the road was ...

Structural optimization of turbine blade firtrees [PDF]
24th Joint Propulsion Conference, 1988 On the basis of the present optimization equation for the structural capacity of a turbine blade attachment firtree, the optimum of the lobe circular fillet radius in the blade and in the turbine disk is determined. In order to further diminish peak stress in firtree design, an elliptical fillet radius is selected in place of the circular one.

Robust Optimal Positioning of Strain Gages on Blades
Journal of Turbomachinery, 2002This paper focuses on the formulation and validation of an automatic strategy for the selection of the locations and directions of strain gages to capture at best the modal response of a blade in a series of modes. These locations and directions are selected to render the strain measurements as robust as possible with respect to random mispositioning ...

Optimization of flatback airfoils for wind turbine blades
Aircraft Engineering and Aerospace Technology, 2010PurposeIn recent years, the airfoil sections with blunt trailing edge (called flatback airfoils) have been proposed for the inboard regions of large wind‐turbine blades because they provide several structural and aerodynamic performance advantages. The purpose of this paper is to optimize the shape of these airfoils for optimal performance using a ...
