Title:
LOADING ASSEMBLY HAVING A SOFT ACTUATOR
Document Type and Number:
WIPO Patent Application WO2000029825
Kind Code:
A9
Abstract:
A loading assembly (2, 88) for applying a load to a test specimen (1, 105) includes a container (4, 6, 97, 98) having a volume of compressible fluid (3) for providing a spring. A cylinder (6, 97) having a bore (5, 94) operably connected to the container (4, 6, 97, 98). A piston (8, 92) is slidable in the bore (5, 94) and is operably coupleable to the test specimen (1, 105). A valve (9, 100) fluidly coupled to the bore (5, 94) selectively provides fluid to the bore (5, 94) to displace the piston (8, 92). A controller (11, 105) controls the valve (9, 100) to cause nonresonant displacement of the piston (8, 92).
