Abstract
A method of testing a sensing device with a sensing mass includes accelerating the sensing device along a circular path about a central axis. The sensing mass of the sensing device may be movable relative to the central axis. The method includes determining a position of the sensing mass of the sensing device via a sensor and shifting the sensing device radially relative to the central axis based at least in part on the position of the sensing mass during acceleration.
Claims17
A method of testing a sensing device, the method comprising:
- accelerating the sensing device along a circular path about a central axis;
- determining a position of a sensing mass of the sensing device via a sensor;
- and
- shifting the sensing device radially relative to the central axis along a track positioned on a beam of a centrifugal testing component based at least in part on the position of the sensing mass during acceleration.
A system for testing an acceleration sensing device with an enclosure housing a sensing mass, the system comprising:
- a platform for securing the acceleration sensing device and that is shiftable relative to a central axis;
- a motor operable to accelerate the platform along a circular path about the central axis;
- an actuator configured to shift the platform relative to the central axis;
- a sensor configured to generate a signal representative of a position of the sensing mass within the enclosure;
- and
- a control system in communication with the sensor and configured to receive the signal from the sensor and cause the actuator to shift the platform along a track based at least in part on the position of the sensing mass so that the sensing mass is maintained within a predetermined range of radiuses from the central axis.
A method of testing an acceleration sensing device, the method comprising:
- accelerating the sensing device along a circular path about a central axis according to an acceleration profile;
- determining a position of a sensing mass housed in an enclosure of the sensing device via an ultrasonic sensor having probes that extend into the enclosure;
- and
- shifting the sensing device radially relative to the central axis along a track positioned on a beam of a centrifugal testing component based at least in part on the position of the sensing mass during acceleration.
