1. Rotorsaksanalys av avvikande ventiler : En fallstudie hos Nordhydraulic AB
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleSammanfattning : Mobila hydrauliska ventiler används ofta i tunga industrier för att styra hydrauliska system för att hantera material. Funktionaliteten är kritisk i dessa situationer då det utgör en miljöfara och säkerhetsfara om funktionaliteten inte är uppnådd. LÄS MER
2. Construction and Control of a 3-axisAutomated Liquid Sampling UnitUtilizing Hybrid Stepper Motors
Master-uppsats, KTH/Mekatronik och inbyggda styrsystemSammanfattning : High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, especially when the tests are many and infrequent. LÄS MER
3. Development of Elastic Mechanism for actuation of Valve
Master-uppsats, KTH/MaskinkonstruktionSammanfattning : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. LÄS MER
4. Design of a Bistable Origami Stent with Pneumatic Actuation
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : What if stents could be easier removed when complications arise or removed once theirjob has been done? No matter how perfect a stent design becomes, the fundamental issueis that a foreign object in the body under extended periods eventually will cause devicedegradation and complications. So instead of making a long-term solution of a perfectstent, the focus in this paper is redirected from expensive materials to a simple design,with simple materials. LÄS MER
5. Evaluation of electric actuation for fighter aircraft
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. LÄS MER
