However, once these vibration isolator parameters are determined, it cannot be changed and high-static-low-dynamic mechanical properties will change under overload or underload
condition, so Daolin Xu et al.

on performance," Human Factors: The Journal of the Human Factors and Ergonomics Society, vol.
The objective is to minimize the total costs, including the value of overload and underload
