说明: 计算简单管道当阀门关闭时管道内的水锤压力。(Calculate the water hammer pressure in a simple pipe when the valve is closed.)
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: SPI计算程序,标准降水指数的计算,利用将降雨资料可以求得。(Spi calculation program, calculation of standard precipitation index, can be obtained by using rainfall data.)
说明: 赤平投影软件 赤平投影安装时间为2010年7月26日。 试用期(一个月)过后,需将系统时间更改为上次安装时间方可继续使用该程序。(The LISP program. The installation time of stereographic projection is July 26, 2010. After the probation period (one month), you need to change the system time to the last installation time before you can continue to use the program.)
说明: 三轴压缩试验的相关PFC3D 5.0代码,供PFC软件的初学者学习。(triaxial compression test)
说明: 该文档为双块式无砟轨道建模命令流,该命令可用于ansys平台运行(This document is the command flow for modeling the double block ballastless track)
说明: 滞回环面积求解,实验数据中滞回曲线的面积计算,采用MATLAB编写。(Solving the area of hysteresis loop)
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.)
