Fatigue life of aero-engine dovetail attachment can be significantly reduced by fretting damage. Taking Ti-6Al-4V alloy aero-engine blade dovetail attachment as an example, a fretting fatigue total life prediction method for complex structure is proposed. A fatigue damage parameter was defined as an...

Nowadays the studies on flutter active control methods considering time delays have been focused on constant time delay in one control channel. However, the time delays in a control loop are maybe time-varying and exist in the forward channel, feedback channel or both. As a result, the control metho...

This paper studies the control problem of approaching and docking autonomously system including an on-orbit servicing spacecraft with flexible appendages and an out-of-control target considering the coupled relative position and attitude dynamic. Choosing the relative position and the relative attit...

Accurate aviation safety prediction is of great significance for preventing accidents. At present, aviation safety prediction is mostly deterministic prediction, which ignores the influence of various uncertainties on the prediction results. Based on the traditional deterministic prediction of aviat...

The elastic moduli of nanoporous copper measured through experiment are much lower than the simulated results from molecular dynamics. And the size of actual ligaments is larger than that used in simulation. In this paper, a stochastic unit cell model of nanoporous material is established in softwar...
