changing frame

By changing the jamb rigidity of the steel track frame ( that means changing the natural frequencies of the steel track frame), the system can be stable during the course of the suspending and loading when other parameters are unaltered.

因此在系统其他参数不变的情况下，通过改变钢轨道框架立柱的侧向刚度，也即改变钢轨道框架的自振频率，可以使系统在慢起慢落过程中稳定。

The concentrated load is applied by changing the axis of rotation of the frame and fork to MPC multipoint restriction.

运用MPC多点约束方式代替了车架和平叉转动轴，并用这种方式对有限元模型施加集中载荷。
