Twist beam


Introduction:-
Twist beam cross member was found failing in field having covered around 34392 Km and was sent for
failure investigation.
Material Observations: - Refer attached Sheets for details.

Remarks:-
1) Material and properties of cross member conforms toE46.
2) Sample has failed near the bracket welding on LH side.
3) Notch like marks as seen on earlier were observed in failed sample indicating unevenness of the plate
which may act as locat ....etc

hello,i am final year student of electrical and electronics engineering
i want to do a mini project on technique for on-line detection of shorts in fields of turbine generator rotor.
what are the shorts and how they occur in turbine generator rotor.
and how to apply this technique , where we can apply this technique,and what are the tools used in this project.
so mail me the complete details of this topic to do as a project as soon as possible ....etc

Numerical simulation of rotor stator interaction is crucial for turbo machinery improvement since it allows the optimization of blade path design In addition the numerical simulation of rotor stator interaction makes it possible to predict the location and variation of hot spots on blades which is extremely useful in the turbine thermal design However simulation of rotor stator interaction is notorious for being computationally expensive To reduce the turnaround time and cost MFLOP a parallel code based on the message passing interface l ....etc

GENERATOR FIELD WINDING SHORTED TURN DETECTION TECHNOLOGY

EFFECTS OF SHORTED TURNS IN ROTOR WINDINGS

The impact of operating a round rotor generator with rotor winding shorted turns depends upon many factors1. If the percentage of total turns shorted out is small, the generator may be able to run at rated load for years without further problems. However, larger shorted turn percentages can cause operating conditions that may limit unit loads. If the proble ....etc

ABSTRACT
The overall goal of the work presented in this thesis is to extend the physical understanding of the external aerodynamics associated with the rotating case of Hovering Rotor using Computational Fluid Dynamics (CFD) technique.
Rotating blades encounter tip vortices coming from preceding blades, which results in Blade Vortex Interaction(BVI) responsible for producing dynamic effects. Understanding the complex flow field due to this dynamic effects produced by wakes is therefore very important for the prediction of effects such as blad ....etc

ACTIVE TWIST OF MODEL ROTAR BLADES WITH D-SPAR DESIGN.


ABSTRACT

The design methodology based on the planning of experiments and response surface technique has been developed for an optimum placement of macro fiber composite (MFC) actuators in the helicopter rotor blades. The baseline helicopter rotor blade consist of D-spar made of UD GFRP, skin made of +45/-45 GFRP, foam core, MFC actuators placement on the skin and balance weight. 3D finite element model of the rotor blade has been built by ANSYS, where the blade skin ....etc
