Estimating of Work Hardening in Bent Sheet Metal Products at an Early Stage of Virtual Product Development
The thesis has two aims: firstly, to investigate the influence of work hardening due to forming simulation on test simulation. The investigated question was also: Is it worth the effort to include work hardening effect into Continue reading
Value-Cost Appraisal of Wind Energy Applying Portfolio Analysis
To meet electricity demand, electric utilities develop portfolio strategies for generation, transmission, and distributions Continue reading
Design and Development of a Spray Booth
As a part of a more extensive project of developing a new finishing line at the Bolivian door manufacturer Tecno Carpinteria San Pedro this thesis presents the development process for a Continue reading
Simulation of Plume-Spacecraft Interaction
When the plume of a thruster impinges on spacecraft surfaces and instruments, the ow is either in the transitional or the free-molecular regime. The standard method to simulate the transitional regime is Direct Simulation Monte-Carlo, which Continue reading
Novel Defrost Techniques on Air Source Heat Pumps
This study aimed to reach a new solution for the defrost problem for air source heat pumps. In order to achieve this goal, the study was divided in 3 different parts. A literature survey about what the Continue reading
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
Numerical Simulation in Automotive Design
Focussing on those areas of simulation which dominate the large-scale computational requirements within the automotive industry, the initial aim of the paper is to give an insight into typical applications and algorithms being used. Beyond this, the main emphasis will be on the more Continue reading
Model Based Diagnosis of an Air Source Heat Pump
The purpose of a heat pump is to control the temperature of an enclosed space. This is done by using heat exchange with a heat source, for example water, air, or ground. In the air source heat pump that has been studied during this project, a refrigerant exchanges heat with the outdoor air and with a 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
Simulation in the Automobile Industry
In this chapter we discuss the use of computer simulation in design and operation of car and truck assembly plants as well as Continue reading
