# Simplified Finite Element Bearing Modeling: With NX Nastran

When conducting finite element analysis on the robots the accuracy of the component modelling and definitions of the boundary conditions becomes more important. One such component is the ball bearing which Continue reading

# Impingement Cooling: Heat Transfer Measurement by Liquid Crystal Thermography

In modern gas turbines parts of combustion chamber and turbine section are under heavy heat load, for example, the rotor inlet temperature is far higher than Continue reading

# Sound Classification of Space in Buildings

On account of LN Akustikmiljö AB, the sound energy absorption of various rooms was estimated using two methods; by measuring the steady-state sound pressure levels in Continue reading

# Aerodynamic Loads on External Stores – Saab 39 Gripen: Evaluation of CFD methods for estimating loads on external stores

External stores mounted on aircraft generate loads which need to be estimated before first takeoff. These loads can be measured in a wind tunnel but since the possible Continue reading

# Accuracy of Transient Versus Steady State Forces on a Rudder Operating in a Propeller Slipstream

In computational fluid dynamics (CFD), a transient simulation is in general more costly than computing the steady state of the system, if such a state exists. The velocity field produced by the propeller blades upstream of Continue reading

# Milling in Hardened Steel – A Study of Tool Wear in Conventional and Dynamic Milling

Milling is a commonly used machining process where a rotating cutter removes material from the workpiece. In recent years, attention has been turned towards so called dynamic milling methods which differ from the conventional way Continue reading

# Evaluating new Pilot Stage Concept

This report is a first practical study of micro valves for hydraulics, manufactured by Microstaq Inc. who uses, for hydraulics, new materials and new Continue reading

# Micromechanical Numeric Investigation of Fiber Bonds in 3D Network Structures

In manufacturing of paper and paperboard, optimized fiber usage has crucial importance for process efficiency and profitability. Dry strength of paper is one of the important quality criteria, which can be improved by Continue reading

# Crack Propagation in Cruciform Welded Joints: Study of Modern Analysis

This study is investigating how the effective notch method can be used for fatigue assessment of welded joints. The effective notch method is based on a finite element analysis where the joint is modeled with all Continue reading

# Modelling & implementation of Aerodynamic Zero-lift Drag into ADAPDT

The objective of this project work was to construct and implement an algorithm into the program ADAPDT to calculate the zero-lift drag profile for defined aircraft geometries. ADAPDT, short for AeroDynamic Analysis and Preliminary Design Tool, is a program that Continue reading
