For obtaining a quasi-static equilibrium state at the end of the pre-simulation, the incorporation of sufficient system damping is a necessity (see Theory manual, chapter Airbag models).
为了在预模拟结束的时候达到准静态平衡状态，需要足够的系统阻尼(见理论手册，气囊模型章节)。

From the viewpoint of nonlinear dynamic system theory, the substance of load forecasting by the loads in similar days is the forecasting for the behaviors of equilibrium points and quasi-periods.
