As shown in Figure 2, the structure of HERSA is designed based on the conventional one.
Mathematic Model of HERSA. Based on the working principle of HERSA shown in the Figure 2, a mathematic model is proposed to demonstrate the system dynamics, such as the damping characteristic.
Prototype of the Cylinder in HERSA. As shown in Figure 3, the prototype of the cylinder in HERSA is fabricated on the basis of a traditional shock absorber according to the conceptual design in Figure 2.
But in the HERSA, the special structure determines the vibration power conversion; one part is converted into heat energy and the other part is converted into electric energy which can be regenerated.
