A nonlinear three-dimensional finite element analysis of exterior RC column-to-steel beam (RCS) connection is performed by ANSYS finite element software. The numerical results, including the lateral load-drift relationship, lateral load-joint shear distortion relationship, shear stress distribution and effective width of the steel web at the last convergence substep, are compared with experimental...
There is higher requirement for warfare simulation in depth and extent. Simulation scales need to be enlarged and more attention should be paid to the precision of warfare simulation. After analyzing the deficiency of traditional platform-level CGF (Computer Generated Forces) model in satisfying simulation requirements, we establish a weapon platform CGF model configuration based on battle crew. The...
The GT-POWER software was used to build the working process model of the diesel engine; through the bench test of the diesel engine, the simulation results were contrasted with the test results to proof the accuracy. The advance angle of injection of diesel engine was optimized at different loads of 2200r/min 1500r/min, the major parameters regularity of the diesel engine was further studied and the...
A force identification technique based on simulation models is proposed and applied to predict the concentrated force at the barycenter of an apparatus. Computation procedure of it is given, in which the model updating and verification steps are included. The mode parameters are used as the base datum for FE model updating. Two verification strategies for the force identification results are introduced,...
Ad hoc network is flexibly formed by a group of peer nodes and depends on the irresponsible cooperation among them, so it is vulnerable to various attacks. Thus, trust is introduced to promote nodes to transmit messages. Nodes with higher trust values are more easily selected for transmission which results in unbalanced load distribution. Therefore, packets from different sources are more likely to...
Saturation effect plays an important role in high performance salient pole synchronous motor control system and the linear magnetic model can hardly depict the static and dynamic characteristics of the motor accurately. In this paper, the magnetic saturation phenomena are characterized by static saturation inductances, dynamic saturation inductances and cross saturation inductances, based on which...
Pin-loaded joints are frequently used to assemble tempered glass panels in the glass curtain walls. The contact between the surface of different parts and the rotation of the pin-loaded joints can not be ignored when the work is concerned about cycling load. This paper investigates all important aspects for modelling the glass panels coupled with pin-loaded joints through carefully parametric studies...
