Center of Gravity and Inertia Testing

S-E-A is a long-time leader in vehicle testing & safety and custom engineering solutions for the transportation industry. Our Vehicle Inertia Measurement Facility (VIMF) is the premier, state-of-the-art system for measuring mass, the center of gravity, and inertia properties. The S-E-A vehicle evaluates center houses testing equipment that is relied upon by the National Highway Traffic Safety Administration (NHTSA) to measure the Static Stability Factor (SSF) of all new model vehicles in the United States as part of the New Car Assessment Program (NCAP). 

That same state-of-the-art equipment is available for use by clients who need the most accurate results possible. The equipment can measure overall mass, the center of gravity and moments and products of inertia on anything from components up to large vehicles.

Types of Gravity and Inertia Testing

The center of gravity and inertia measurements can be performed on new vehicles and equipment to predict how it will perform in different scenarios. Our facilities are large enough to test everything from individual components up to heavy machinery and military vehicles.  The tests are computer controlled with database management capability and provide accurate feedback. 

Commonly tested items include, but are not limited to, the following, and S-E-A is equipped to handle one-off cases for other items as well: 

  • Passenger vehicles
  • Off-Road Vehicles (ATVs, ROVs & Golf Carts)
  • Military vehicles
  • Heavy trucks
  • Engines and powertrains
  • Wheels and tires
  • Seat assemblies

Most of the items S-E-A tests in this manner are from the automotive and transportation industries because this information is most relevant to their specific needs. Inertia measurement of engines and powertrains can help determine the optimal location for engine mounts and reduce NVH. Learn more about engine inertia testing.
