摘要： A testing machine includes a base, at least a pair of columns joined to the base and a crosshead joined to the columns at a location spaced apart from the base. At least a pair of specimen holders are provided. A first specimen holder is supported by the crosshead and faces the base, and a second specimen holder is supported by the base, the base being that portion joined to each of the columns closest to the crosshead. An actuator connected in series between one of the specimen holders and the corresponding base or crosshead. A brace connected to each of the columns and spanning between the columns, the brace being connected to each of the columns at a location along a length thereof between the base and the crosshead.

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.

摘要： A method of constructing an electric linear displacement motor for use in a testing device includes providing a stator having as stator housing with internal coils and a through bore extending from a first end of the stator housing to the second end of the housing. First and second end supports are connected to the first and second ends of the stator housing. An armature having magnets retained therein is inserted into the stator housing such of the armature is supported by the first end support and the second end support. A plurality of set screws are inserted into threaded openings proximate both the first end and the second end of the housing. The set screws then support and retain the armature such that there is an annular gap between the armature and the coils.

摘要： A tire testing machine includes a tire and wheel assembly having a sensor configured to measure a parameter related to the tire and wheel assembly as it rotates on a rotating element. A holder supports the tire and wheel assembly. A processor is configured to receive an input at least based on the output signal from the sensor, and provide an output signal indicative of a parameter of a contact patch between a tire of the tire and wheel assembly and the rotating element. Controlled element(s) are configured to vary a parameter related to the contact patch and/or friction.
