The Scott-Russel horizontal isolator is a straight line linkage. When this structure is used, the stored energy can be reduced as much as possible, making the isolation system achieve a very low natural frequency. However, because of the existence of the weight of the isolator, the natural frequency is not as low as expected. In this paper, the equation of motion of the Scott-Russel isolator is proposed to find a method to reduce the natural frequency by choosing reasonable parameters and using the zero-length spring.
