Abstract: Based
on mechanism analysis of hydraulic power and servo systems, the primary
failure modes of hydraulic systems are briefly introduced. According to
the key and difficult topics on diagnosis of power and servo subsystems,
the theories, the approaches and the developing situation of fault
diagnosis technology in recent years are comprehensive analyzed and
summed up. By summarizing the advantages, limitations and applicable
areas of each method, suggestions and comments are given for further
research efforts.
Key words:
