Proposal number EXAW-1999-01540
Proposal titleHYBRID ACTUATOR TESTING SYSTEM
AbstractAll transportation systems , including aircraft, suffer from fatigue failures. To ensure that
components and systems reach their target life times durability testing is carried out. The
generation of very high forcing levels required, at both low and high frequencies currently
requires complex and expensive equipment. The choices open to a company needing to
test is between; electromagnetic shakers and servo hydraulic actuators. In both cases the
costs involved are high and more importantly the performances are always compromised.
The impact on the environment through the use of these systems is typically high as they
invariably use large electronic amplifiers or hydraulic plant that consumes 100's of kW of
power. The HATS system will use the SMART material TERFENOL-D to produce a
composite actuator . The actuator will comprise a low frequency hydraulic ram and high
frequency Magnetstrictive force actuator aligned in series.
