摘要： An environmental chamber includes an enclosure having opposed walls each wall having an aperture of size to receive a test specimen support therethrough. The apertures are aligned with each other along on a reference axis. A forced air source is configured to supply forced air in a direction to intersect with the reference axis within the enclosure. A diverter is positioned between the forced air source and the reference axis. The diverter is configured to receive the forced air and control the air flow past different portions of the reference axis. The environmental chamber is used with a load frame having test specimen supports extending into the opposed apertures. A method of directing more force air at the test specimen supports than at at least a portion of the test specimen to maintain a selected temperature gradient in the test specimen is also provided.

摘要： A testing machine includes a pair of vertical columns, a crosshead selectively positionable on the vertical columns, and a head assembly supported by and movable with the crosshead. The head assembly has an electric actuator, a support that can be selectively moved from a first position when the test machine is operated to a lowered position. The support supporting components are related to powering or controlling the electric actuator, said components are exposed for servicing in the lowered position.

摘要： A test system includes a frame. A hydraulic actuator is mounted to the frame and is configured to support a test specimen. A piezoelectric actuator is configured to apply a force to the test specimen. A controller is configured to excite the piezoelectric actuator and provide an indication of force generated by the piezoelectric actuator by measurement of current or charge provided to the piezoelectric actuator.

摘要： An electric machine includes a housing, a rotor rotatably supported by the housing for rotation about a longitudinal axis and a stator assembly fixed secured to the housing spaced apart from a surface of the rotor and concentric with the rotor about the longitudinal axis. The stator assembly includes a stator winding comprising circumferentially spaced apart stator teeth about the longitudinal axis, the stator teeth having remote ends proximate the surface of the rotor. A plurality of sealed cooling channels extend parallel to the longitudinal axis and are disposed between remote ends of successive teeth. The cooling channels are formed in resin of the stator assembly, the cooling channels being fluidly connected to ports in a closed system to circulate cooling fluid to cool the stator assembly and configured to remove heat from the stator assembly proximate the rotor surface. Other aspects include methods of making such machines.

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： Systems and methods are provided for controlling the simulation of a coupled hybrid dynamic system. A physical test rig configured to drive the physical structure component of the system and to generate a test rig response as a result of applying a test rig drive signal. A processor is configured with a virtual model of a complementary system to the physical structure component. The processor receives the test rig response and generates a response of the complementary system based on a received test rig response. The system can be driven with a random input. The processor compares the test rig response with the response of the complementary system, the difference being used to form a system dynamic response model.
