摘要:
A test specimen holder (20, 21) includes a specimen engaging portion (30) operable to selectively engage and hold a test specimen (11). The test specimen holder (20, 21) includes a first shield (34) disposed around the specimen engaging portion (30) wherein a first gap (36) is formed between the shield (34) and the specimen engaging portion (30) to remove heat from the specimen engaging portion (30).
摘要:
A mobile or cloud communication platform for a test facility to monitor various testing devices. The mobile communication platform is configured to transmit data or information to a remote test platform remote from a test facility or laboratory. In some embodiments described, the communication platform is configured to interface with the one or more controller units to receive input or output data from the one or more test devices and transmit the input output data to the remote test platform via a messaging protocol initiated by the communication platform coupled to the testing device. Various graphical user interfaces are further described.
摘要:
A transducer senses repetitive pulses on a magnetostrictive element and provides transducer output bursts. A transducer circuit detects the transducer output bursts. An energy storage device couples to a power input of the transducer circuit. A switching power supply couples to the energy storage device and has repetitive suppressed states during which switching in the switching power supply is suppressed. A sequence circuit provides synchronization of the repetitive suppressed states of the switching power supply with the transducer output bursts.
摘要:
A test system and method for testing a coupled hybrid dynamic system in simulated motion along a path (242) includes a physical test rig (206) configured to test a physical component (208). A processor (30) is configured with modeled test data (218), a first virtual model portion and a second virtual model portion of the coupled hybrid dynamic system, the first virtual model portion (204), the second virtual model (202) portion and the physical component (80) comprising the coupled hybrid dynamic system. The processor (30) is configured to control the test rig (206) such that the component under test (208) responds to the second virtual model portion (202), that in turn receives a first input (272) comprising the modeled test data (218), a second input (216) being motion of the first virtual model portion (204) of the coupled hybrid dynamic system, a third input (214) being a control mode response from the test rig having (206) the physical component (208) under test and a fourth input (272) comprising guidance controls for the coupled hybrid dynamic system.
摘要:
An autonomous vehicle control system (e.g., 105; 600) for use on a vehicle, such as a motorcycle (e.g., 100) or an all-terrain vehicle (ATV) to autonomously control the vehicle without a driver during vehicle testing is provided. The vehicle control system comprises a moment generator (e.g., 110) coupleable to the vehicle and configured to selectively generate a moment in either of first and second directions. The vehicle control system also includes a control system (e.g., 112; 120; 800) operably coupled to the moment generator and configured to control the moment generator to selectively impart moments on the vehicle to stabilize the vehicle or to introduce disturbances on the vehicle.
