两个磁铁之间力
本帖最后由 y1949b 于 2009-1-19 00:25 编辑上传：用maxwell ，求两个磁铁之间的相互作用力的文件。
里面只介绍了，求解的的步骤。
至于磁铁的大小，之间的距离，就根据自己的需求来拟定吧。
我模拟了一下，跟我计算的差不多。。。
有一本书，推荐一下。。。
书名“Magnetic Actuators and Sensors” ， 作者是 John R. Brauer
里面介绍了大量的理论和模拟步骤。上传的内容，也是书上的。
值得看看，就是有点贵。
全文内容为：
【Force between two permanent magnets
Solution:
1. Set the Maxwell “Solver” to “Magnetostatic” and its ”Drawing”
to “RZ” plane. In “Define model” enter two boxes along the left
(z) axis for the two magnets.
2. In “Set up Materials” choose “NdFe35” for both magnets, and
set their angle of magnetization 90 degree. Which is vertical
with the north pole on top.
3. Under “set up boundaries/sources” no sources need to be
specified, since the permanent magnets be specified on the
outer boundary of the model, since there is no steel to confine
the flux. A balloon boundary is a type of open boundary that
allows flux to leave the finite-element model space.
4. Use “set up executive parameters” to specify force computation
on the lower magnet.
5. Under “set up solution options”, change the number of passed
to 23. This high number is needed so that when “Solve” is
clicked, the energy error will be below 2%】 好东西啊，看看啊 怎样计算铁与磁石之间的吸力呢？我想了很久都没有答案。。。 晕，附件只有模拟部分。我还以为有楼主自己的计算方法呢！ 謝謝，樓主！ Magnetic Actuators and Sensors” ， 作者是 John R. Brauer
