Monash Motorsport takes advantage of optimization and additive manufacturing technologies and wins again!

Since their first Australian SAE Student Racing competition in 2000, the Monash Motorsport team has steadily improved the performance of their race car. Recently the students discovered the benefits of combining Altair‘s OptiStruct optimization technology and 3D printing. Based on an initial prototype rear hub design from the 2013 car, the team proceeded to pursue titanium front hubs and uprights to decrease the car’s unsprung mass. This was a tough challenge, since the former design was already made of lightweight aluminum. To tackle this, Monash Motorsport employed Altair’s optimization technology OptiStruct to design and optimize a titanium upright, which was then produced using additive manufacturing technology from CSIRO. As a result, the students were able to reduce the component’s weight by a further 30 percent whilst maintaining the component stiffness and reducing the development time and costs.

A Multifunctional Aerospace Smart Skin Emerges from Computational Models and Physical Experiments

The capability to assess the current or future state of the health of an aircraft to improve safety, availability, and reliability while reducing maintenance costs has been a continuous goal for decades. Many companies, government agencies, and academic institutions have become interested in Integrated Vehicle Health Management (IVHM) and a growing effort of research into “smart” vehicle sensing systems has emerged. Methods to detect damage to aircraft materials and structures have historically relied on visual inspection during pre-flight or post-flight operations by flight and ground crews. More quantitative non-destructive investigations with various instruments and sensors have traditionally been performed when the aircraft is out of operational service during major scheduled maintenance. Through the use of reliable sensors coupled with data monitoring, data mining, and data analysis techniques, the health state of a vehicle can be detected in-situ.
