Hybrid joints have better tensile properties than pure bonded and bolted bolts, and are increasingly used in the aerospace field. Tensile tests are carried out for the Hybrid Bonded/Bolted(HBB) joints of Carbon Fiber Reinforced Polymer(CFRP) laminate and titanium alloy plate under different bolt numbers, and the corresponding load–displacement curves are obtained. At the same time, based on Continuum Damage Mechanics(CDM) theory, which is derived from 3D Hashin failure criteria, and a Cohesive Z... 相似文献

In this paper, we consider the double-satellite localization under the earth ellipsoid model of the Wideband Geodetic System(WGS-84) using the Time Difference of Arrival(TDOA)and the Angle-of-Arrival(AOA).Several closed-form solution algorithms via the pseudolinearization of the measurement equations are presented to efficiently estimate the location.These algorithms include the Weighted Least Squares(WLS), the Constrained Total Least Squares(CTLS), and the Taylor-Series Iteration(TSI).Performance comparison of the proposed methods with the Cramér-Rao Lower Bound(CRLB) in the simulation is shown to demonstrate that the proposed algorithms are feasible and have stable performance. 相似文献

High Performance Propulsion System Advanced Research Program(HPPSARP) is state-supported and carried out under the charge of Gas Turbine Establishment. HPPSARP has been making great contributions to catching up the advanced world levels and shortening technological gaps between PRC and developed countries. This special issue crystalizes the cream of HPPSARP's strength projects, which have come to the end. The other projects of the HPPSARP will be summed up into the coming special issues while completed. 相似文献

In some special cases of flight simulation (e.g. for formation flight, in-flight tanking) it is required to generate a two-dimensional field of turbulence, in which the turbulent wind speeds are stochastic functions of two coordinates (e.g. x in the flight direction and y in the wing span direction). For this purpose a simple and efficient technique for the digital generation of a two-dimensional field of turbulence,i.e. for the production of turbulent speed sequences on a rectangular network, is proposed in this paper. The correlation of the turbulent field so generated is found to be in good agreement with the theoretical correlation of the turbulence model, and thus the feasibility of the proposed method is verified. Two possible operation modes (off-line and on-line) of the turbulence generator in flight simulation are also discussed. 相似文献
