Chassis Design for SAE Racer
University of Southern Queensland Faculty of Engineering and Surveying Chassis Design for SAE Racer A dissertation submitted by: Anthony M O’Neill In fulfilment of the requirements of ENG 4111/2 Research Project Towards the degree of Bachelor of Engineering (Mechanical) Submitted: October 2005 1 Abstract This dissertation concerns the design and construction of a chassis for the Formula SAE-Aust race vehicle – to be entered by the Motorsport Team of the University of Southern Queensland. The chassis chosen was the space frame – this was selected over the platform and unitary styles due to ease of manufacture, strength, reliability and cost. A platform chassis can be very strong, but at the penalty of excessive weight. The unitary chassis / body is very expensive to set up, and is generally used for large production runs or Formula 1 style vehicles. The space frame is simple to design and easy to fabricate – requiring only the skills and equipment found in a normal small engineering / welding workshop. The choice of material from which to make the space frame was from plain low carbon steel, AISI-SAE 4130 (‘chrome-moly’) or aluminium. The aluminium, though light, suffered from potential fatigue problems, and required precise heat / aging treatment after welding. The SAE 4130, though strong, is very expensive and also required proper heat treatment after welding, lest the joints be brittle. The plain low carbon steel met the structural requirements, did not need any heat treatments, and had the very real benefits of a low price and ready availability. It was also very economical to purchase in ERW (electric resistance welded) form, though CDS (cold drawn seamless) or DOM (drawn over mandrel) would have been preferable – though, unfortunately, much more expensive. -

PART III: Carlsbad Caverns National Park, New Mexico The “main focus” of our five-day trip, in the early spring of 1952, was extended time to visit two locations—Carlsbad Caverns National Park, in the southeastern part of the State of New Mexico, and Ciudad Juarez, Mexico—across the International Border from El Paso, Texas, which lies in the far western tip of Texas. A beautiful morning awaited as we rose from our beds in the small motel in the town of Carlsbad, New Mexico. Out in the parking lot, in front of our room, the Hudson was covered with a thick layer of dust, accumulated during our long drive through Colorado and New Mexico. No rain in sight to help wash the car off, but my dad pulled into a Texaco Gas Station in town to refuel, and have the attendant check the oil and clean the windshields and side windows for us. (While living in Denver, Colorado, my dad often frequented a favorite Texaco Station on Colorado Blvd., not far from our first house on Birch Street.) In a friendly tone, and looking at our license plates, which read “Colorful Colorado,” the station attendant asked, “How far have you folks come? Headed for the Caverns I bet! Any time of year is a good time to go, ya’ know! Doesn’t matter what the temperature is on the outside today, cause deep in the Caverns the temperature is the same year round—56°.” Motel Stevens in Carlsbad, New Mexico.

Now on View in the Entrance of Art Los Angeles Contemporary, Ramada Santa Monica Is the Fourth Iteration in Mark Hagen's Serie
Now on view in the entrance of Art Los Angeles Contemporary, Ramada Santa Monica is the fourth iteration in Mark Hagen’s series of space frame installations—this time housing the catalog of materials from independent publisher Artbook | D.A.P. Aluminum triangles join into modular architectural units, towering floor to ceiling and enclosing a corner of the lobby, where polished fossils (in fact fossilized feces) act as bookends. We've seen the future and we're not going titles Hagen’s 2012 space frame work, that one affixed with rough slabs of obsidian. The pleasure of this uneasy pairing springs from its clever twinning of aesthetics and eras of technology: the irregular cuts of obsidian with the uniformity of the space frame, the material of prehistoric weaponry with the template for 1950s modular design. We’ve seen the future and we’re not going both rejects technological accelerationism and admits a melancholic truth: our utopian techno-future simply has not come. This ambivalence about technology, the failure of positivism to deliver on its promises, animates Hagen’s space frame sculptures, as they call out to (and become implicated in) the sinister evolution of the form. In the middle of the twentieth century, space frames were perfected by utopian architect Buckminster Fuller in his geodesic domes. Now, luxury car manufactures including Audi and Lamborghini advertise their use of the space frame, testifying to the recherché design. This evolution is unsurprising. Buckminster Fuller’s ideals of totalizing efficiency as well as neologisms like “synergy” find exquisite expression in corporate management; the hippie communes founded on his principles collapsed within the decade. -

Mankind is always enhances the compression capacity and shows better attempted to utilize the maximum space for the structure. The performance of space frame structure [10]. need for modern structures is to achieve a large clear span The present paper focuses on the basic concept of a space with the economy. Now-days it is observed that there is a frame system. And also on the studies carried out by several growing interest in space frame systems. A space frame is a 3D researchers for understanding the structural behavior of the structural system in which well-organized linear axial space frame system by considering various parameters. elements are put together for the uniform distribution of forces. The main purpose to use these systems is to cover a large span area and giving a pleasant appearance to the 2. SPACE FRAME SYSTEM structure. Also, the space frames are light in weight and can easily be transported to the site. The objective of this paper is 2.1 Introduction to present the detailed concept of space frame systems and applications of these systems. -

Das gilt auch für die überall geplanten großen Infrastrukturprojekte, die durch ihren Flächenverbrauch die Pufferkapazität der Natur schwächen und schon beim Bau und durch die verwendeten Baustoffe wie Beton, Stahl, Asphalt etc. große Mengen an Treibhausgasen freisetzen. Das Projekt Stuttgart21 gehört dazu und würde – erkennt man den Irrtum, mit schnellem Verkehr Zeit im System zu sparen, nicht rechtzeitig – die gleichen negativen Folgen haben. Im System ist der Verkehr nur ein Teilsystem aber mit Folgen für alles Professor Knoflacher hier mit seinem andere.

Aus einer Größe, die im System nicht nachweisbar, also Null ist, kann man daher keinen Nutzen berechnen und damit auch keine öffentlichen Mittel begründen. Ebenso wenig, wie durch Autobahnprojekte, wie den Lobautunnel1 durch das Naturschutz- und Erholungsgebiet des Biosphärenparks an der Donau, um nur ein Beispiel zu nennen. Ich beglückwünsche die Stuttgart21-Gegner*innen, mit ihrem neuen Umstiegs-Vorschlag hier einen großen Stein ins Wasser geworfen zu ha- ben. Wenn das dazu führt, dass bei Stuttgart21 nicht noch mehr Klimaschäden angerichtet werden – umso besser! Die Städte müssen von dem überbordenden motorisierten Verkehr entlastet werden. Wenn das in Stuttgart durch die Nutzung der schon gebau- ten Tunnel möglich ist, dann ist das ein wesentliches Plus dieses Konzepts.
