I setup a model such as spring with a translational hard stop in parallel. The recorded force (vs time) should approach zero while the slider in the stop approach the bound during simulation, isn't it? But the graph showed the force vs time was still linearly increased no matter the parameters changed. Is there something error, or I didn't really know the meaning of the hard stop?

Would you mind sharing the force you are using? Please provide your schematic diagram.

The hard stop has a stiffness value, which, if less than applied force, would allow a translation. For example, if applied force is 20N and hard stop stiffness is 10N/m, it will allow the spring to move beyond the upper bount for up to 2 m.
