Shooting Target - Konstruktion : Product DevelopmentBergkvist, Marcus, Åkerblom, Christopher January 2014 (has links)
The shooting sport is one of the most widespread sports in the world and it is being practice in most countries. Based on their own experiences, in competition - and hobby shooting, the client M4Solutions found a demand and need for a shooting target that is manufactured in Sweden. The purpose of the project has been to develop, with the help of Marcus Walldén, two shooting targets from idea to finished product. These two shooting targets, Plate Rack Target and Dueling Tree, would each be equipped with a mechanical resetting system but will in the future have the ability to be provided with an electronic resetting system. The project from the client was divided into two theses. One of these two, written by Marcus Walldén, focused on the tripod parts and the overall design work for both Plate Rack Target and Dueling Tree. The thesis that is presented in this report have focused on resetting systems, the design of protective plates and other peripherals for both shooting targets. This work has primarily been in CAD environment where design, construction and development has been given free rein. Calculations, test shootings and choice of materials has been made in order to reach the best possible solutions. The thesis resulted in two complete 3D models and two full-scale prototypes of steel.

En undersökning om användandet av additiv tillverkning inom motorsportAngerbjörn, eran1804 January 2021 (has links)
Utvecklingen av produkter inom motorsporten är viktig ur flera aspekter. Dels för att miljöaspekten kring motorsport är mer aktuell än någonsin och för att ny teknologi gör det möjligt att optimera fordonen mer. Den här rapporten handlar om att optimera ett insug till en specifik förbränningsmotor, Volvos motor B234 16v. Insuget modelleras i programmet SolidWorks, där en CAD-fil tas fram. Från denna CAD-modell ska insuget sedan konstrueras genom additiv tillverkning. Uppgiften var att optimera gasflödet och producera en produkt som är lättare än originalprodukten, i ett polymermaterial som klarar de temperatur och lösningsmedelskrav som ett insug till en förbränningsmotor kräver. Reverse engineering användes för att matcha de båda flänsarna på varsin sida om insuget mot motor och spjällhus. Ett antal olika versioner av insug modellerades och testades för optimalt gasflöde. Från detta valdes den bäst flödande versionen ut. En polymer, PA12 (polyamide) Nylon glasfilled, presenterades som det bäst tänkbara materialet för den additiva tillverkningen av insuget. Genom att använda det presenterade materialet kunde en viktminskning på 37% uppnås. Det färdiga insuget skall sedan testas i motorbänk av uppdragsgivaren för att jämföras med ett insug som modifierats efter Trendabs ursprungliga process. Efter arbetet kunde det konstateras att processen som använts i arbetet inte bara är sparar pengar åt uppdragsgivaren, men även sparar tid i form av arbete som kan lejas bort istället för att göras in-house. Det framgick även att reverse engineering kunde göras med goda resultat utan att använda avancerad skannerteknik. Istället kan konstruktören utgå ifrån den del som skall modifieras för att använda mått och bilder för skapandet av CAD-modellen / <p>Betyg 2021-07-16</p>

Framtagning av en ny E-DUO-koncepttrailer : Ett hållbart koncept för framtida E-DUO-trailer / Developing of a new E-DUO-concept trailerSateei, Shiva, Fernvik, Lovisa January 2021 (has links)
I dagens samhälle spelar miljön en viktig roll, både för hur miljön skall bevaras och hur miljöproblem kan undvikas. Med detta uppmanas allt fler människor ha en större miljömedvetenhet. Miljöproblemet är ytterst märkbart i infrastrukturen och främst transporter av dess olika slag. Större fordon, såsom lastbilar, färdas långa sträckor för att transportera gods som i sin tur ökar bränsleförbrukning och gör att utsläppen blir allt mer. Genom att öka lasten, per transporterad enhet, på de tyngre fordonen så kan bränsleförbrukningen minskas. Företaget Parator Industri AB som tillverkar lastbilstrailers är med i ett HCT-projekt (High Capacity Transport) där de tillsammans med andra involverade företag ska ta fram en ny konstruktion av tyngre fordon med ett hållbarhetstänk.Syftet med detta examensarbete är att är att ta fram en lösning för kombination av en lastbil med kopplat släp vilket senare kommer utgöra produktionsunderlaget till företaget Parator. Detta genom att hjälpa företaget konstruera en ny DUO-trailern som kommer bestå av två chassin som ska sammanfogas och som kommer transportera containrar med gods i. Genom aktionsforskning med fokus på intervjuer och observationer, har vetenskapliga källor samlats in. Detta kombineras med modellering på dataprogrammet SolidWorks där 3D-modellering av den nya konstruktionen utförs. Med överslagsberäkning beräknas hållfastheten fram på den nya trailerns infästningar. Även ett nytt produktionsunderlag, med tillhörande materiallista och ritningar har tagits fram i rapporten. Studien har vidare analyserat huruvida de tillämpade tillverkningsmetoderna samt monteringar kan vara hållbara ur ett produktionsperspektiv. / Today the environment is a common question and how to reduce emissions into nature. With this more people are encouraged to have an environmental mindset. Mostly the environmental damage comes from the transport with different kinds of vehicles and their exhaust gas. Larger vehicles, such as trucks, travel long distances to deliver goods which increases fuel consumption and increases emissions. By increasing the load, per transported unit on the heavier vehicles, fuel consumption can be reduced. The company Parator Industry AB that designs truck-trailers is involved in an HCT-project (High Capacity Transport) together with other companies where the goal for the company is to achieve a more sustainable production material and have less impact on nature.The purpose of this study is to find a solution for a combination of the truck connected with a trailer which will later form the production basis for the company Parator. This by helping the company design a new DUO-trailer which will consist of two chassis to be joined and will transport containers with goods. Through action research with a focus on interviews and observations, scientific sources can be collected. This will be combined with modeling on the computer program SolidWorks where 3Dmodeling of the new design is performed.Estimated value of the design is done for the new attachments. The study also contains a production base with produced drawings and material list. The study also analyzes the relevance of the calculated values and if they will be sustainable in the future.

Analýza mechanického namáhání při zkratu ve vzduchem izolovaném rozváděči vn / Analysis of Mechanical Stress during Short Circuit in an Air-Insulated MV SwitchgearBártů, Jan January 2017 (has links)
This Master thesis is based on problems of force effects of the magnetic field of short-circuit current. Firstly, I analysed the force action of the three phase busbars during the three-pole short circuit. The analysis was performed in the Ansys Maxwell program and I verified the correctness of the analysis by numerical calculation. The second practical part was executed for ABB company. The main task was to analyse the force effects of the short-circuit current in the HV switchgear with focusing on the arms and contact system of the circuit breaker. The simulations of the following configurations were performed in more details: three configurations of the simplified VD4 circuit breaker, two types of VD4 circuit-breaker contact systems and a linear circuit breaker configuration model. The objective was to calculate the forces acting on the current path of the arms and contact system of the VD4 circuit breaker during the three-phase short-circuit and to simulate the effects of forces on these current parts. For modelling of individual assemblies, calculations and simulations I used: SolidWorks 2014, Ansys Maxwell 16.0 and Ansys Workbench 14.5 programs. With SolidWorks 2014 3D CAD software were modelled simplified assemblies of circuit breakers and contact systems. These systems were imported into the Ansys Maxwell software, where the force effects of the magnetic field of the short-circuit current were calculated. In Ansys Workbench programme was simulated the effect of forces on the current circuit breakers. Moreover, the final deformations of the materials (with respect to the mechanical properties of the structure) were plotted. The analysis of force effects of the magnetic field was performed for the specified static short - circuit current value.
