CUSTOM REPAIR PROGRAM FOR SERVO VALVES KEEPS TEST RIGS RUNNING

摘要

Proving grounds aren't always the most effective way to test the durability of a truck or car. If a car maker wants to evaluate, for example, a light truck frame or suspension, then testing groups often get a call to simulate any number of road conditions. The results from strength, compression, and vibration tests help car makers build a better product. Michigan-based Exova is an example of a testing group that conducts simulations using equipment such as an 18-channel, full-vehicle inertial road simulator. "We can complete some tests in a day; others take more time," says Jeff Taylor, supervisor of the Exova Defiance Technical Services Group. "A testing program for a frame maker can last more than a year."
