用有限元分析软件ansys来仿真模拟火车过桥的过程中桥的受力分析(The deformation of high-speed railway track was simulated by ansys)

说明：  基于vue+element的电商后台管理系统，完整实现了整个流程。 该项目为前后端分离项目，搭建步骤具体参考后端项目传送门。(Based on Vue element, the whole process is realized. This project is a front-end and back-end separation project. It builds a portal with specific reference to the back-end project.)

降维状态观测器是非常重要的一类观测器 基于P变换的降维观测器设计方法，(Reduced-order state observer is a very important class of observer-based P Transform reduced order observer design method)

第一届飞思卡尔智能车比赛的程序 希望对大家有用-Freescale" s first smart car race program hope for all of us

说明：  以悬臂梁为例，用有限元法编程生成质量矩阵和刚度矩阵（采用平面梁单元，单元数在10到30之间）。 使用matlab的用于广义特征值问题分析的函数（eig(A,B,'chol')，该命令使用乔莱斯基分解的方法，计算对称矩阵A和对称正定矩阵B的广义特征值问题。A对应刚度矩阵，B对应质量矩阵）计算梁的前三阶固有频率和振型，计算得到梁的前三阶固有频率和振型，并画出振型图。(Taking cantilever beam as an example, the mass matrix and stiffness matrix are programmed by finite element method (using planar beam elements, with units ranging from 10 to 30). Using Matlab's function (eig (A, B,'chol') for the generalized eigenvalue problem analysis, the command uses the Jo Lessky decomposition method to calculate the generalized eigenvalue problem of the symmetric matrix A and the symmetric positive definite matrix B. A corresponds to the stiffness matrix and B corresponding to the mass matrix. The first three natural frequencies and modes of the beam are calculated, and the first three natural frequencies and modes of the beams are calculated, and the vibration pattern is drawn.)

说明：  多选项卡图片切换是一款类似多级导航菜单的jQu(Multi-tab image switching is a JQ similar to multi-level navigation menu)

说明：  讲解了如何三维视觉的一些介绍，包括如何理解坐标变换。(Some introductions on how to use three-dimensional vision, including how to understand coordinate transformation, are explained.)

说明：  在非均匀线阵条件下的DOA估计算法（4种）(DOA estimation algorithm under the condition of nonuniform linear array (4 kinds))
