[英]How can I change the stiffness of spring during analysis in Abaqus.?
For example, I have this statik system: enter image description here例如,我有这个 statik 系统:在此处输入图像描述
My goal:我的目标:
I want to investigate the behavior of the beam, when a stiffness of the spring is changed during analysis我想研究梁的行为,当弹簧的刚度在分析过程中发生变化时
At the "Step-1" the system is loaded by means of concentrated load "F".在“Step-1”,系统通过集中加载“F”加载。
I want:我想:
At "Step-2" the system shall be loaded by means of same load "F", but the stiffness of spring shall be changed.在“步骤 2”,系统应使用相同的载荷“F”加载,但应改变弹簧的刚度。
Because of, the spring is not a type of boundary conditions in Abaqus, I can't change the stiffness at "Step-2".因为,弹簧不是 Abaqus 中的一种边界条件,我不能在“Step-2”改变刚度。 I can change the stiffness after a "job" is finished.
我可以在“工作”完成后改变刚度。 It means, that I have alwas a new system.
这意味着,我一直是一个新系统。 I want to change the stiffness in already deformed system.
我想改变已经变形系统的刚度。
Many thanks in advance!提前谢谢了!
You can define the dependency of spring stiffness on a field variable.您可以定义弹簧刚度对字段变量的依赖性。 Then controlling this variable will let you change the stiffness as needed.
然后控制这个变量可以让你根据需要改变刚度。
