AUTOMOTIVE INDUSTRY

Space Electronics offers a wide variety of mass properties testing solutions for the automotive industry:

   • Our small moment of inertia (XR series) instruments are used to test components such as gearboxes, transmissions, crankshafts, clutches, flywheels, pistons, rocker arms, connecting rods, steering wheels, doors, hatchbacks, and more. Reducing moment of inertia is especially important to the car racing industry, where lower moment of inertia of moving engine and transmission components translates into a net gain in power transmitted to the wheels.

   • Our small center of gravity (SE8913 and SE90168 series) instruments are widely used to measure the center of gravity location of the same components as above.

   • Our larger instruments (KSR and MP Series) are used to measure moment of inertia and center of gravity location of engines and entire vehicles. Lowering the center of gravity of the car is an essential goal to the car racing industry, because it impacts stability and handling in curves.

In addition to selling measurement equipment, Space Electronics also offers measurement services. These measurements can be performed at our facilities or at the customer's site.

Measurement of CG and MOI of a car In order to get center of gravity and moment of inertia in 3 axes, an object needs to be placed on the KSR instrument in 3 orthogonal positions. This is not practical for a car. The alternate solution is to tilt the car by 20 degrees in two axes and to extrapolate the results for 90 degrees. The extraordinary precision of our KSR series of instruments allows very precise results with this method (better than 0.1 mm for CG and better than 0.5% for MOI).
