A built rivet machine is experiencing a bending moment that makes it "yawn" when it rivets, which causes a bad rivet operation. The purpose is to analyze and find the reaseon for the caused problem. Method: A computer based machine design analysis will be performed and the achieved results will be compared with actual measured ones. When a satisfied result i achieved redesign will be per

The purpose of this work has been to perform numerical calculations on the cubical mixing tank the QB mixer, to be able to verify its strength and try to improve it. The QB mixer is produced by the company QB FoodTech AB. Firstly a CAD model was made from drawings of the mixer. Then the structure was analysed in aspects of pressure load, thermal loads and gravitational load. A modal analysis to ge
The task consisted in helping Tetra Pak with the problem that they today have with unexplained deformation of their creasing carriages. Tetra Pak uses different carriages depending on which kind of packaging that is to be manufactured. The carriages are hauled in and pulled in to the production line when another type of packaging is to be manufactured. Basically the carriages look the same, the th
This master thesis is commissioned by the company Haldex Brake Products AB based in Landskrona. The company is acting on the road vehicle market. Amongst other products the company produces disc brakes for the heavy road vehicle industry. Disc brakes developed by Haldex, based on the sliding caliper principle, are during certain circumstances experiencing problems with malfunction of the brake due
The purpose of this thesis was to examine how fasteners for mobile phone housing in metal sheet could be designed. The assignment was defined by Sony Ericsson Mobile Communication and the work was done in close cooperation with them. Sony Ericsson has had metal in their covers before but only as a cosmetic layer, the bearing parts have been made in moulded plastic. The reason to make a cover where
This Master Thesis was carried out in cooperation with BAE Systems Hägglunds in Örnsköldsvik and its purpose is to improve the efficiency of the hydraulic system for the cooling fan drive in the track driven military vehicle BvS10. The efficiency of the pump and motors are summarized using data from the subcontractors and the efficiency of the pipe line system is derived using Bernoulli’s formula
This paper is for understanding the gap between city commercial banks and state-owned banks. In our image, the gap is exsiting for a long time, but how large is large, could it be changed. Through the quantitative analysis using CAMEL rating system, the conclusion is the performance of city commercial banks is wearker than state-owned banks from capital adequacy, assets quality, management, earnin
Vår definition av Aktiva handelssystem är ”Ett datorsystem som, efter fördefinierade variabler, automatiskt köper och säljer värdepapper. Systemet aktiverar köp och sälj – order helt baserat på teknisk analys”. Denna typ av system finns fortfarande inte i de större organisationerna men kan komma att implementeras i framtiden. Frågeställningen är vad som krävs för att göra denna implementering lyck
