A QUALITY CONTROL SYSTEM FOR TESTING MECHANICAL DEVICES

摘要

The present invention relates to a quality control system for testing devices, such as mechanical devices with moving parts, such as electro motors, comprising a fixture adapted to hold and operationally engage with the device, at least one energy flow transducer being positioned at the fixture so as to be operational communication with the device when the device is operationally engaged with the fixture, the transducer sensing acceleration of and force exerted by the device, and providing electrical output signals in response to and as a function of sensed acceleration and forces, respectively, and a measuring apparatus for receiving the output signals from the at least one energy flow transducer, and for determining parameters derived from sensed forces and accelerations.
