California State University, Fullerton's Formula SAE chapter is back from their brief break to build another beast of a race car. Using Q-PLUS Labs' 3D scanning expertise to aid them, the team enters into their 3rd year in the challenging Formula SAE competition which encompasses designing, building, and competing a mini-formula style race car that will be evaluated for its potential as a production item.

Introduction

This year, California State University, Fullerton's Formula SAE is using a Yamaha FZ-07 motorcycle engine which has increased displacement for their new race car design. The new design for the chassis will include a space frame as well as a carbon fiber driver cell. The space frame is created by welding steel tubes together and attaching them to the cockpit and the engine housing, as well as the drive train. Unlike the team's last design which was a stressed engine, this design will be mounted to the inside of the space frame. Weighing 20 to 30 pounds less than the team's original engine, this choice also offers more torque and faster acceleration without creating a heavier car which would give the team an edge against their competition.

Our Process

Because the final race car's design needs to be both fast and safe and relies on the integrity of the engine's measurements, Cal State Fullerton's SAE sought the expertise of Q-PLUS Labs' dimensional measurement engineers. Using the Steinbichler Comet 5, Q-PLUS Labs was able to provide CSUF's SAE team with accurate measurements of the engine to provide the structure for the race car's design. Using these points from the scan data, the team can proceed to confidently to create a CAD model of the car designed with both the driver's safety and structural integrity in mind.

California State University, Fullerton’s Titan Baja SAE (Society of Automotive Engineers) team is back at it again preparing for their 2016 competition season and sought Q-PLUS Labs' measurement expertise to 3D scan a crucial component of their new vehicle, dubbed the Hyperion, the second iteration of the team’s 2015 race car, the Cronos which Q-PLUS Labs aided with 3D scanning last year. Their 2015 design of the Cronos not only competed, but beat out half the competition! This year, the team is dialing in on a design that works best for the most random and unpredictable off-road terrain which the race has been known to throw at competitors.

Introduction

A little background on the rigorous Baja SAE race—it originated in 1976 at the University of South Carolina as a comprehensive engineering competition with the objective for students to function as a team and not only design, build, test, promote, and race a vehicle, but also raise financial support while balancing the demands of their course work. In order to compete as formidable opponent at the 2016 Baja SAE race, the final single-seat, all-terrain sporting vehicle is comprised of parts machined by CSUF’s Baja team.

This year, the team decided to integrate a cutting brake into the vehicle’s design. Because the race course terrain consists of extreme conditions, installing a cutting brake would help mitigate the unpredictable conditions and make the vehicle more maneuverable. It accomplishes this by working in line with the rear brake system to isolate specific wheels, giving the driver greater control of the car and facilitating with sharp terms.

Our Process

The cutting brake’s measurements are extremely vital to the vehicle’s ability to successfully navigate the race due to the challenging track. CSUF’s Baja team requested Q-PLUS Labs to 3D scan the cutting brake that provided the team with measurement data from which they can derive the best fit area of the car to mount the brake. Using the Steinbichler Comet 5, Q-PLUS Labs was able to give the team precise measurement data for the cutting brake, allowing a new model to be water jetted accurately while reducing the amount of time it would have taken the team to acquire the measurements manually, and helping them quickly prepare for their 2016 race in Gorman, California May 19th-22nd.

The University of California, San Diego requested Q-PLUS Labs for a unique onsite 3D scanning project of the Something Pacific installation for the Stuart Collection. This installation by Nam June Paik consists of two parts, an indoor exhibit found in the lobby of the university's Media Center as well as 3 statues of tiny Buddhas staring at dead TV sets embedded throughout the landscape UCSD's Communications/Media Center building. The resulting scans will be used to reproduce the Buddha statues in detail should they be damaged or stolen.

Introduction

Nam June Paik designed this installation which is composed of televisions paired with Buddhas watching them to depict extended contemplation. As an integral aspect of UCSD's landscape, the university sought to preserve the statues via 3D scan data in case the statues would need to be recreated in detail. For this particular application, Q-PLUS Labs' engineers used white light and laser scanning technology, specifically the Steinbichler COMET L3D and the Faro Edge ScanArm HD.

Our Process

Even with high tech 3D scanning equipment, obtaining accurate and detailed scans in an outdoor and uncontrolled environment was a meticulous process. Because the statues were unmovable and anchored into the ground, the engineers established a controlled scan environment by carefully tenting each statue to block excessive lighting.

Being in an outdoor environment, the statues required thorough and careful cleaning as well as a trench dug around each statue to render more of the statues' surface area for greater scan detail. The freeform and unusual geometry of each statue also provided a challenge to obtain scan details. However, Q-PLUS Labs' engineers completed the job and the scan data produced will help to preserve this interesting exhibit for years to come.
