摘要:Aeroelastic instability problems have become an increasingly important issue due to the increased use of larger horizontal axis wind turbines. To maintain these large structures in a stable manner, the blade design process should include studies on the dynamic stability of t...

摘要:Abstract(#br)Wind shear can strongly influence the cyclic loading on horizontal axis wind turbine blades. These load fluctuation causes a variation of power output and introduces fatigue load. Thus, individual pitch controllers have been developed that are focused on the load all...

摘要:Abstract(#br)The FPGA (field programmable gate array) manufactured by using the CCGA484 (ceramic column grid array 484) package has been increasingly growing in demand day by day. However, the CCGA484 package has not been evaluated in space programs yet. In addition, the CCGA484 ...

摘要:Abstract(#br)The magnitude and temporal variations of wind speed considerably influence aerodynamic and structural responses of MW-sized horizontal axis wind turbines. Thus, this paper investigates the variations in airloads and blade behavior of a wind turbine blade resulti...

摘要:Abstract(#br)Metal-coated optical fiber sensors (MCOFSs) have a memory effect due to the elasto-plastic characteristics of the metal coating. Our study is first implementation of a new concept for damage evaluation of composite plates using the memory effect of MCOFSs. Quasi-stat...

摘要:Abstract(#br)Tin-coated FBG sensors, which can be used to evaluate the maximum strain experienced by host structures through the quantity of residual strain induced by the tin coating, were fabricated by a dipping method. The residual strain development of the tin-coated FBG sens...

摘要:Abstract(#br)A new kind of composite piezoelectric ceramics for large-displacement actuators, which were composed of reduced and unreduced layers, was prepared from normal PZT by chemical reduction. The stress distribution inside the composite PZT was researched and the chemical ...
