Brake Testing & Analysis

  Brake Tester

With over a decade of experience, BEAR has tested and analyzed brake systems and components on passenger and commercial cars and trucks.

The BEAR system to the left tests automobile master cylinders:

  1. Foot pressure is measured and recorded via the load cell and PC data aquisition.
  2. Pressure guages are attached to the master cylinder as a redundant analog monitoring system. This also permits the detection of front or rear system pressure discrepencies.
  3. Linear displacement is also measured and logged automatically.
  4. Custom programing eliminates the need for time consuming conversions and calculations.
  Brake The BEAR brake system tester at left, determines if the brakes are functioning properly in place. Full computational analysis can be performed in conjunction with testing to determine the behavior of any braking system.  

Impact Analysis


This FEA capability allows us to perform full 3D impact analysis with multiple colliding bodies, including automobile collisions, crane tip-overs, ladder and chair accidents, and more. Rigid and deformable body motion can be analyzed, as well as models that contain both. (For example, in an automobile collision, the front of the automobile that deforms is modeled with deformable elements, and the rear of the automobile can be modeled as a rigid body to reduce the time necessary to run the analysis without losing significant information or accuracy.) These complex models can include human (dummy) components, as well as seat belts and airbags, to determine the dynamic response of a person in the analysis.

  Failure or damage, such as tearing, fracture, and buckling, can be computed as a function of time for any components being modeled. This method can be applied to components made of ceramics, steel, plastic, concrete, soil, or any other material. If you would like more information, or have a problem you would like us to analyze, please call or email David Rondinone or Glen Stevick.
