刚度计算

hhj502066714

请问下列的刚度该如何计算，或者如何运用作图方式获得？
‘Stiffness’ was determined by the following procedure:
Unit loads were applied in the global X- and Y-directions at the ball joint.
All analyses were run a second time with the Young’s modulus scaled by a factor of 100.
The difference between the two displacements (deformable displacement – 100X stiffer displacement) at the load application point was used to calculate the stiffness.

不是非常明白，大体说说：
由于你施加unit loads的point是一个ball joint，所以施加以后的displacement包含两个部分:刚体位移和实际变形。使用你说述的方法就是求取实际变形的办法。希望对你有用！

多谢2#参与讨论。
首先ball joint是一个零件，其中施加的载荷作用在该零件的一个作用点上。不明白算法中英文的算法是如何实现计算，因为最后一句英文没有理解。至于displacement应该是有X、Y方向的区别，分别有一个刚度值。
