Abstract: The electro-hydraulic load simulator is a key equipment for
hardware-in-loop simulation of aircraft. The simulation creditability is
directly related to the load trace precise. There is no identified
estimation standard for it now, which causes some misunderstand for the
design and implementation. Some estimation methods are summarized, which
problems are disclosed. Furthermore, it is illustrated from two sides.
First, presents the evaluation methods for the performance of load
simulator; On the other hand, to require the performance of the load
simulator by evaluating the actuator, mainly discuss the influence of
the dynamic stiffness of the actuator.
Key words: Estimation criteria Actuator Dynamic stiffness
Extraneous force Trace of load spectrum Load simulator
