As a follow-up to our previous blog “Damper Performance Testing”, we will discuss damper durability testing.
As a follow-up to our previous blog “Damper Performance Testing”, we will discuss damper durability testing. Once a damper or a shock absorber is characterized for a specific vehicle or condition, it is essential that its durability or service life of the damper is tested too. The seal package, damping fluid, and other structural components’ endurance are tested during a durability test.
OEM shock absorber manufacturers and suppliers need to perform such durability tests in an accelerated manner, where the damper is subjected to cyclic sinusoidal, random, or sine-on-sine curves. The durability testing is usually conducted under a controlled temperature, so that the damper is not subjected to artificial thermal loads that it would not be exposed to in real-life operation. We can perform environmentally controlled durability testing of dampers for more than 1 million cycles. The tests can be performed 24/7 to offer time-effective test solutions to our customers.
AMAD, Inc. ‘s facility is equipped with an MTS 852 Damper Test System to serve automotive, aerospace, and other industries that require characterization of shock absorbers. With damper force capability of up to 24,500 lbfs, 10 inches of travel, and 250 in/s operating velocity AMAD, Inc. can serve testing needs of all automotive, aerospace and military industries. With our environmental chamber installed on the damper test system, we can also simulate arctic operating conditions, as low as -70℉ and extremely hot temperatures exceeding 400℉. We also have the capability to control relative humidity between 5-95% for testing between 70-180℉.
