Newman Haas Racing engineers have a spring in their step now that they've figured a way to ensure that changes in springs in their suspension systems won't alter the balance of their cars.
The team, which races in CART events, is using MATLAB software and the MATLAB Data Acquisition Toolbox to test the springs, which determine the wheel rate, roll rate, and load transfer responses to acceleration, braking, and turning forces. Engineers are also using the software to test bump rubbers and push-rod load cells.
Newman Haas engineers used C++ to create a custom user interface that works with MATLAB.
The FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
