请教ANSYS模型导入ADAMS中的单位转换问题

x-tay

在ANSYS中用梁单元建立柔性体导入ADAMS，在ANSYS中采用mmks单位，加速度g=9800，力的单位应该为1E-3N，材料为钢材，对应的弹性模量2.06E8，质量7.85E-6，生成MNF文件时单位设置为/UNIT,USER,1000,1,1
导入ADAMS后，发现长度、质量、力都没问题，但是弹性模量好像大了1000倍，变形只有1/1000，请问下是哪里有问题

附上ANSYS中生成MNF文件的命令流，谢谢了~

USER defined units for Export to ADAMS：
If you specify user defined units, a Define User Units dialog box will appear for you to input the conversion factors (for length, mass, force, and time) between SI (meter, kilogram, newton and second) units and your chosen units. Below is an example of user defined units in which the component has been modeled using millimeter, tonne (metric ton), newton, and second.
Length Factor = 1 meter/millimeter = 1000
Mass Factor = 1 kilogram/tonne = 0.001
Force Factor = 1 newton/newton = 1
Time Factor = 1 second/second = 1

就是这里出问题了，之前把那几个系数对应的单位弄错了，现在对了，多谢了~

我也遇到这样的单位制问题，输出的曲线单位高不清楚
