如何从ansys 中进行结构动力分析如何得到加速度数据？
本帖最后由 wdhd 于 2016-4-15 09:54 编辑大家好!很高兴从这里见到这么多专家高手，我是刚刚从事钢结构健康检测方面的研究，现在遇到一个难题，请恳请高人相助：
对一单跨四层钢结构进行动力响应分析，跨度是0.9米，层高是1.2米，材料采用H150*150*7*10，想加一高斯白噪声作为激励，不知道如何才能得到加速度。恳请各位专家高手相助!万分感谢!急!

回复 楼主 zql_progress 的帖子
可以在matlab中生成高斯白噪声！ 如果你的ansys版本大于8.0的话,可以从结果文件直接提取加速度变量。否则的话，只能得到位移变量，然后对位移做时间的二次差分。补充：求助：但是我不知道怎么将matlab生成的白噪声信号加到ansys里？
非常感谢楼上两位的解答！但是我不知道怎么将matlab生成的白噪声信号加到ansys里？ 恳请各位专家能给予补充说明，我刚开始做这方面的研究，用matlab程序生成的白噪声如下：clear;
x=randn(1,1000);
x=x/std(x);
x=x-mean(x);
a=0; %均值
b=1; %方差
y=a+sqrt(b)*x;%产生均值零，方差为1的高斯噪声
plot(y)
clear;
x=randn(1,1000);
x=x/std(x);
x=x-mean(x);
a=0; %均值
b=1; %方差
y=a+sqrt(b)*x;%产生均值零，方差为1的高斯噪声
plot(y)
同时用下面的命令产生了一些数据，不过产生的数据看不懂，针对我的问题，恳请大侠能给小弟解释一下！十分感谢！
clear;
x=randn(1,1000);
x=x/std(x);
