轨道不平顺

abaqus的平板塑性圆孔数值模拟源文件，适合abaqus新手操作练习使用(ABAQUS source files for numerical simulation of plate constraints, suitable for ABAQUS novice operation exercises)

说明：  3维米塞斯屈服准则模型，子程序为vumat，用于abaqus(ABAQUS 3-dimensional Mises yield criterion)

abaqus的平板约束数值模拟源文件，适合abaqus新手操作练习使用(ABAQUS source files for numerical simulation of plate constraints, suitable for ABAQUS novice operation exercises)

说明：  精细积分法Matlab程序，利用该程序对动力系统的微分方程精细求解。(The program of precise integration method MATLAB is used to solve the differential equation of dynamic system precisely.)

说明：  使用有限元方法，可以直接求解加筋板结构的质量刚度矩阵(Using the finite element method, the mass stiffness matrix of stiffened plate structure can be solved directly)

说明：  简易的配筋软件，适用CAD2014及以下版本。(Simple reinforcement software, applicable to CAD2014 and below version.)

说明：  可利用八节点有限单元进行力学分析，荷载形式可以为点荷载或均布荷载等形式(This code can be used for mechanical analysis of eight-node quadrilateral element, and it is suitable for various load forms such as concentrated load, uniform load and so on.)

说明：  ansys命令流，计算由于振动引起的高层建筑物的表面振动加速度，不过激励是施加在土体上的(ANSYS command flow is used to calculate the surface vibration acceleration of high-rise buildings caused by vibration, but the excitation is applied to the soil)

说明：  利用ansys建立输电塔模型，并进行模态分析。(The transmission tower model is established by ANSYS, and the modal analysis is carried out.)

说明：  三层框架，瑞雷阻尼。 激励是白噪声。 先计算得到理论的响应时程，理论频率，再利用响应做峰值法识别频率模态，与理论频率对比。 程序只写到了画ANPSD曲线，还需要自己写一个拾取峰值的代码。(Three story frame, Rayleigh damping. The excitation is white noise. First, the theoretical response time history and frequency are calculated, and then the peak response method is used to identify the frequency mode, which is compared with the theoretical frequency. Later, you need to write a code to pick up the frequency corresponding to the peak value.)
