It has been demonstrated that the buckling-restrained steel plate shear wall (SPSW) is an efficient and economic lateral load-resisting system exhibiting high performance on initial stiffness, ductility, shear resistance, and energy dissipation capacity. In present study, a novel partially connected buckling-restrained SPSW is presented to reduce the stiffness requirement for the vertical boundary...
Application of traditional design methods and finite element analysis method of comparative analysis of modern design, by design and analysis to 1HS-1.2 deep tillage profiling spring, subsoiler make a good job of solving the deep pine uneven surface operations on the quality of sub soiling, subsoiler operation to ensure consistent uniform depth.
This paper is based on the body characteristic of Permanent Magnetic Synchronous Motor, progress motor parameter matching in accordance with the drive requirement of the vehicle, progress simulation by use of finite element analysis software an soft Maxwell 12 and vehicle simulation software advisor, and carry out the parameter optimization of the motor. The simulation results show that the optimized...
The MOP (Massive Ordnance Penetrator) is non-nuclear earth penetrator weapon which has the best damage effectiveness now. The targets of MOP will be deeply underground headquarters and hard deeply buried targets. It has been simulated by using LS-DYNA finite-element software to analyze damage effectiveness of MOP, especially the relation of minimal depth of the defense cover. and span length, which...
BLU-113 is earth penetrator warhead commonly used. It has been simulated by using LS-DYNA finite-element software to analyze damage effectiveness of BLU-113, which BLU-113 attacks underground protective works under different deepness from 10 to 22 m. In the simulation, shotcrete layers, anchor-hold rocks and loose rocks are taken into account. The penetration process and explosive process of BLU-113...
Simulation is the important method for shock-resistant ability design of shipboard equipment. And shipboard equipment shock-resistant ability is the one of important factor of ship life ability. Four-missile launcher resistant shock ability has been evaluated by American navy dynamic design analysis method (DDAM). The four-missile launcher has maximal value of displacement at Z direction, and has...
Explosion damage effect of Massive Ordnance Penetrator (MOP) is more than 10 times the explosive power of its predecessor, the BLU-109. The targets of MOP will be deeply underground headquarters and hard deeply buried targets. It has been simulated by using LS-DYNA finite-element software to analyze damage effect of MOP, which MOP attacks underground protective works under different deepness from...
A simplified implementation method of feed and load in higher order finite element method (FEM) with perfect matching layer (PML) for solving radiation problem is researched By applying a probe model with FEM mesh preprocessing for the feed and load, the difficulties from dealing with the higher order face and volume base functions are overcome and the precision is guaranteed in the meantime. Correctness...
