有加速度曲线，怎么滤波，怎么提取等效加速度曲线呢？
有加速度曲线，怎么滤波，怎么提取等效加速度曲线呢？还请各路大侠指点！！！！谢谢！ 不懂，不过同想知道。很好奇是不是用傅里叶之类的东西，或者有专门的插件或者工具来做这个变化。或者分离。

滤波可以在hypergraph 做
Exercise: Filtering a curve Step 1: Open Session File saefilter.mvw
1.From the File menu, click Open > Session.
2.Select the file <installation_directory>/tutorials/mv_hv_hg/plotting/saefilter.mvw and click Open.
Step 2: Filter a curve using the SAE J211/1 filter.
1.Click on the Define Curves panel button file:///D:/Program%20Files/Altair/11.0/help/hwtut/curvescreate-24.png.
2.Click Add and add a new curve.
3.Change the name of the new curve from Curve 1 to SAE J211/1 FILTER in the text box over the curve list.
4.Check the radio button for Math under Source:.
5.Verify that the x vector is active.
6.Hold the SHIFT key and click on the curve in the plot window.
The x = curve reference is p1w1c1.x.
7.Click the y = field, and click Filter… from the panel menu to display the Filter dialog.
8.Select the filter class SAE J211/1 from the Filter Class drop-down menu.
9.Select Filter Class: 60, Padding: Mirror padding, and Direction: Fwd-Back.
10.Click OK to complete the selection and close the Filter dialog.
11.Hold down the SHIFT + CTRL keys, then select the existing curve.
12.The x vector curve reference is entered in the saefilt95 function.
13.Hold down the SHIFT key and select the curve again.
Note: the curve's y vector is referenced in the saefilt95 function. The y = field should read: saefilt95(p1w1c1.x,p1w1c1.y,60,1,3).
14.Click Apply to create the filtered curve.
