    Abstract: A testing apparatus (12) includes a crosshead (151) and a head assembly (150). The head assembly (150) includes a head cover (156) having an interior volume (182). An electric actuator (152), controls and other electric components (158) are located within the interior volume (182, 184), wherein the motor (152), controls and other electric components (158) generate heat when energized. A divider (170) within the interior volume (182, 184) separates a first volume (182) from a second volume (184). The first volume (182) includes the heat generating electric motor (152), controls and electric components (158) and the second volume (184) contains substantially no heat generating components. The head assembly (150) includes at least one fan (202) within the second volume that draws cool air from outside the head cover (156) and forces the cool air through the second volume (184) and into the first volume (182) to remove heat.

    Abstract: A force applicator assembly (10; 10') is disclosed to calibrate an in-situ force transducer (or load cell) (104) in a force (load) applying test machine (125). The force applicator (10) includes stationary member (22; 22') configured to be secured to fixed structure, a moving member (20; 20'), a load cell (12) operably coupled to an end of the moving member (20; 20'); and a differential screw assembly (24; 24") connecting the moving member (20; 20') to the stationary member (22; 22'). A coupling assembly (14) can be used to assure that only tension or compression loads are applied. The coupling assembly (14) can be configured if desired such that no tension or compression loads can be applied. A method to calibrate an in-situ force transducer (104) in a force applying test machine (205) is also provided and uses a force generator (16; 16'; 125) and the coupling assembly (14).

    Abstract: A method of constructing an electric linear displacement motor (20) for use in a testing device (12) includes providing a stator (22) having as stator housing (28) with internal coils (23) and a through bore extending from a first end (34) of the stator housing (28) to the second end (36) of the housing (28). First and second end supports (54 and 56) are connected to the first and second ends (34 and 36) of the stator housing (28). An armature (24) having magnets retained therein is inserted into the stator housing (28) such of the armature (24) is supported by the first end support (54) and the second end support (56). A plurality of set screws (60) are inserted into threaded openings (32) proximate both the first end and the second end (34 and 36) of the housing(28). The set screws (60) then support and retain the armature (24) such that there is an annular gap between the armature (24) and the coils (23).
