Gravity Load in Abaqus (Abaqus中重力荷载的施加)

Abaqus的Standard模块中,重力通过指定材料的密度、定义静力加载步并施加重力加速度的方式来施加。

In Abaqus/Standard, gravity load are specified by three steps: define the density property of material, define static loading step and apply gravitational acceleration load to the whole model.

    您好啊,在abaqus里我给结构某一点施加一个加速度激励,然后在另一端输出,类似于应力波传播的,这样能实现吗?

      可以,超常规地震动力时程分析就类似你说的这个。

    你好,我现在利用Abaqus计算一个变形体小球入水的问题,在load中设置重力场为-9.8,但为什么计算结果显示加速度初始值不是-9.8 ,而是一个0.几的值?

    abaqus中重力加速度不应该是以mm/s2为单位吗崔博?
