摘要:
对耦合双摆模型中的测度同步现象进行了研究。该系统是一个哈密顿系统。主要对悬挂在同一横梁下的两个双摆的一个非耗散耦合系统进行分析。通过系统哈密顿量得到系统的运动方程,改变系统耦合强度R(横梁质量与摆上小球质量之比),计算摆角随时间演化图,相空间轨迹图,摆的平均能量图来研究本物理系统到达测度同步现象。当耦合参数达到并且小于临界耦合参数时,从中可以观察到耦合双复摆系统达到了测度同步的状态。该研究完善对于测度同步现象的认知。

摘要:
设k≥2是正整数,P=e^(2/kπJ),其中J=(0 In-In 0)是标准辛矩阵.在本文中,我们证明,对R^(2n)中任意P循环对称紧星型超曲面Σ,Σ上至少存在一个P循环对称闭特征,其中n≥2;此外,我们给出星型超曲面上存在n个几何不同P循环对称闭特征的一个充分性条件.

摘要:
本文考虑二阶哈密顿系统-ü(t)+L(t)u(t)= μu(t)+Wu(t,u(t))(t ∈ R)(HS)同宿轨道解的存在性.其中W∈ C1(R×RN,R),L(t)∈ C(R,RN2)是对称矩阵函数,且满足强制条件(L),μ是参数,且位于(HS)对应的特征值问题-ü(t)+L(t)u(t)= λu(t)的某两个特征值之间,即λk<μ<λk+1.再假设W在无穷远处满足次二次增长条件,通过临界点理论和指标理论,可证明(HS)的多重同宿轨道解的存在性.

摘要:
辛算法作为研究哈密顿系统长期定性演化的最佳积分工具,自问世以来就受到了很大的关注.通过对哈密顿函数的截断误差分析,可以从不同角度构造出较高精度的辛算法,也可以通过引入正规化技术实现自动调整积分步长和改善数值稳定性.从辛算法的表现形式可以将它分为显式和隐式两种.当哈密顿系统能够分解为几个可积部分且每部分的解能用时间显函数来表示时,可以构造显式算法.显式算法有非力梯度显式辛算法、力梯度辛算法、辛校正、类高阶辛算法四种.当哈密顿系统变量不能分离时,适合应用隐式辛算法和扩充相空间对称算法求解.分别对这些算法的构造方法及其适用的物理模型进行归纳对比,分析了各种辛算法的优劣性和发展趋势,对如何选择辛算法高效高精度地解决实际问题提供了一定的理论和数值计算依据.

摘要:
运用判定函数方法,借助数值计算方法研究了一类五次哈密顿系统在四次多项式扰动下的极限环分支情况,通过获得的判断曲线得出系统可以分支出4个极限环,而且4个极限环的情况有((2,0),2)和((0,2),2)二种分布形式.使用数值探测方法对所得结果进行了模拟检验,并且给出了4个极限环的具体位置.

摘要:
为了改进永磁同步电机(PMSM)调速系统,提出一种基于无源性控制技术的永磁同步电机控制策略.在永磁同步电机端口受控哈密顿系统的建模基础上,利用互联、阻尼配置的无源性控制方法得到d,q轴电压,利用二自由度控制技术能实时矫正系统受到的各种外扰的特点,设计了二自由度控制器.仿真结果表明,该控制策略能够有效地改善系统的整体性能.

摘要:
本文将广义位移和动量同时用拉格朗日多项式近似,并选择积分区间左端位移和右端动量为独立变量,或选择积分区间左端动量和右端位移为独立变量,然后基于对偶变量变分原理导出了哈密顿系统的离散正则变换和对应的数值积分保辛算法.当位移和动量的拉格朗日多项式近似阶数满足一定条件时,可以自然导出保辛算法的不动点格式.通过数值算例讨论了位移和动量采用不同阶次插值所需最少Gauss 积分点个数,并讨论了位移插值阶数、动量插值阶数以及Gauss 积分点个数对保辛算法精度的影响,说明了上述不动点格式恰好是一种最优格式.

摘要:
In this paper, the dynamic buckling of elastic cylindrical shells, which are impacted by axial step loads on one end, is theoretical analyzed in Hamiltonian system. A approach is employed to convert fundamental control equations into Hamiltonian canonical equations, which is shown in dual variables. In the system, critical loads and buckling modes are reduced to a problem of symplectic eigenvalues and eigensolutions. The primary factors, including impact time, boundary conditions, thickness and inertia force, etc,that affect critical loads and the corresponding buckling modes are investigated in detail. It is shown that buckling waveforms can be divided into two sorts according to different solving domains. The minimum critical loads belonging to different sorts have also an obvious discrepancy. The results give analytically and numerically some new rules of buckling problem, which is useful in designing structures of shells.
