The dynamic large deflection response of RC beams under low-speed impact loading at their midspan is investigated in this paper. Two simple methods such as extended Hamilton’s principle and equivalent static hypothesis are used to establish the theoretical models for both simply supported fully clamped beams; analytical formulas maximum deflection-input energy obtained. “equal area” method based on history only during these derivations determine plastic bending moment stress distribution...
The load-carrying capacity of the symmetrical and asymmetrical sandwich beams, under a quasi-static central load, is investigated in this paper. Three collapse mechanisms such as face yield, core shear indentation are considered for beams. Core mechanism taken into account fully clamped Continuity equations established by simple ‘equal area’ method postyield behavior beams yield at different boundary conditions. In theoretical model, effect local denting on large deflection beam account....
For a novel electric vehicle equipped with 2-speed Inverse Automated Manual Transmission (I-AMT), optimal design of the gear ratios is carried out using dynamic programming (DP) under constraints. Given multiple driving cycles, target to make obtain best energy consumption economy. After are determined, performance compared same single-speed box, and it shown that transmission has much better performacne in terms acceleration time, maximum speed
It is necessary to investigate the characteristics and evolution law of metal deformation by using appropriate strain analysis method. The complex, so there exists no useful method amalyze local describe global equivalent deformed metal. In this paper, we propose a statistical moment analysis. Statistical builds up relationship between micro quantities macro strain. For instance, it used study deformations monocrystal under uniaxial load nanocrystalline shear shock, showing that can not only...
Missile equipment support system is a complex involving mission profile, operating environment, personnel, resource scheduling, and other factors, most of the failures are process continuous evolution over time. Based on characteristics functions or performance parameters current detection methods, only part health degradation trend can be monitored. Therefore, it necessary to carry out simulation considering failure state comprehensively. In this paper, mission-oriented modeling framework...
In order to obtain the accurate thrust rod load, based on theory of multi body dynamics, establish complete vehicle virtual prototype model by using ADAMS software, dynamic simulation load time history. Combined with MATLAB software build three-dimensional space pavement harmonic superposition method, obtaining under different conditions, results show that, loaded uphill turn largest, and bear in various working upper than lower load. Consistent experimental results, illustrate modeling...
A series of main-chain liquid-crystalline polymers containing maltose were synthesized by interfacial condensation reactions sebacyl chloride, 4,4’-Dihydroxy-2,2’-dimethyl Benzalazine(DDBA), and 1-O-[4´-O-(α-D-glucopyranosyl)-ß-D-glucopyranosyl]-methanol(MM). The effects MM on characteristics properties studied. P1- P3 exhibited nematic mesophase heating cooling cycle, while P4- P7 both chiral smectic mesophases cycle cycle. P8 did not exhibit any glass-transition temperature decreased with...

针对导弹装备, 尤其是新研装备或历史经验数据欠缺的装备, 在设计阶段保障方案规划不合理的问题, 提出了一种多扰动下面向设计的导弹装备保障系统仿真方法。构建了分层分块的混合递阶仿真框架, 抽象出装备保障过程中的装备类、保障类、管理类、环境类智能体, 并根据保障流程确定了这4类智能体的交互机制及信息传递链路。分析了影响装备保障决策的2类扰动, 建立了装备故障扰动和人员失误扰动模型, 采用双时钟机制实现仿真过程中的扰动注入, 并根据装备维修保障流程及智能体状态跃迁过程建立了保障系统的恢复行为模型。选取了某型导弹装备开展实例仿真, 将保障资源仿真结果与装备初始设计方案和装备实际需求情况进行对比, 验证了仿真系统的正确性, 为在设计阶段制定合理科学的装备保障方案提供了新思路。
