Mechanical Testing

Request Information

Our mechanical engineering services use classical methods of statics, dynamics, thermodynamics, fluid mechanics, as well as experimental and computational tools to understand components and systems.

The Rexnord Innovation Center test and analysis laboratory is equipped with load frames, servohydraulic actuators and controls, open architecture test beds, environmental chambers, electrodynamic shakers, and other state-of-the-art equipment to meet our customers' test requirements.

Shock and Vibration Testing Overview

Industries Served:

  • Aerospace
  • Food & Beverage
  • Automotive
  • Mining
  • Construction & Machinery
  • Transportation & Shipping
  • Energy
  • Water Management

Load Fatigue & Durability

Fatigue is involved in up to 70% of all product failures. Testing modes include axial, torsion, bending, radial, oscillatory, or full rotation. We specialize in modifying standard test specifications to simulate actual component use.

Shock & Vibration

The Rexnord Innovation Center offers several ways to perform shock and vibration testing. Our engineers are equipped with a wide range of hydraulic actuators, fixtures, control systems and calibrated measurement instruments. However, it is our experience and ingenuity that customers value most.

We help clients to establish a logical shock and vibration test system, run the tests and assist in any resulting redesign activities. Our closed loop acceleration feedback control can simulate almost any shock or vibration environment that your product may encounter. This includes, but goes well beyond, industry and military shock and vibration testing methods established by IEC, SAE, MIL-STD, ISO, ASTM, RTCA and the Department of Defense (DOD).
