I'd like to build a model like picture below, apply exteral vibration to the "Mechanical Translational Reference"( which is wall in this case), the mass is in contact with the wall at the begining, but can be separated if enough force genereate to overcome the spring force, the spring is attached to the wall and mass, can simscape build this model?

Hi cheng,

I understand that you want to model a base excited spring-mass system with the mass constrained to move between 2 walls.

Translational Hard Stop block can be used for modelling the constraint and the base excitation can be provided using an Ideal Translational Velocity Source block.

You can refer to the below model:
