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. Additionally, our engineers have access to the most advanced accident investigation equipment in the industry.

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, product and cross products of inertia on anything from components up to large vehicles. The flexibility of our products allows them to add value across many industries.

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. It is also instrumental in accident investigations because it can shed light on how a vehicle would have performed in the conditions leading to an incident.

Our facilities are large enough to test everything from individual components up to heavy machinery and military vehicles -- so there is almost no limit to our capabilities. The tests are all managed by computer systems and software to 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:

  • Military vehicles
  • Heavy trucks
  • Passenger vehicles
  • Recreational vehicles
  • Engines and powertrains
  • Wheels and tires
  • Seat assemblies

Most of the items S-E-A tests in this manner are from the automotive, transportation, and legal 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.

Center of Gravity and Inertia Testing Services

These services are useful for automotive manufacturers and safety assessors because the tests show how capable a vehicle is of withstanding certain conditions and situations on the road. The tests can also bring light to insurance claims and court cases. Legal professionals have a stronger case when their positions are supported by hard evidence from a leading source like S-E-A.

The thorough data collection and evaluation provides our engineers with empirical evidence that supports their professional opinion. For legal proceedings, S-E-A’s team presents their findings in clear reports. Reports often include visual components or animations that can make huge impacts in a courtroom. Contact vehicledynamics@sealimited.com to see how they can help your investigation.
