“…In order to improve vehicle performance without significantly changing the cost of suspension system, Ref. [3] studies the passive suspension system for heavy goods vehicles. To improve the performance without requiring complex control strategies, a new combined passive and active vibration suppression approach is proposed in Ref.…”

The zero-stiffness structure has excellent vibration attenuation performance. In this paper, a new type of zero-stiffness vibration isolator is designed, and the vibration isolation effect is simulated and analyzed. Furthermore, the zero-stiffness isolator is applied to the McPherson suspension, and the improved McPherson suspension model is obtained. Under the excitation of the bump road and C-level Road, the performance of the improved suspension is simulated, and the responses of the vehicle body vertical acceleration and suspension deflection are analyzed, and compared with that of the original suspension. The results show that, under two cases, the vertical acceleration of the improved suspension is reduced by 92.5% and 65.4% compared with the original suspension respectively, and the stability speed is also greatly improved.

“…The stiffness and damping of the passive suspension cannot be adjusted automatically, but the suspension parameters have a significant impact on the ride comfort and vehicle damage on the road. [4][5][6] The semi-active suspension is extensively used in heavy vehicles given its low cost and simple manufacturing process. Most semi-active suspensions are realized by variable dampers, 7,8 and many control method have been used for the semi-active suspension of heavy vehicles.…”

In order to comprehensively improve the ride comfort performance and the road friendliness performance of the heavy vehicles, an inertial suspension using ground-hook (GH) control is proposed in this paper, and the suspension performances are compared at different loading rates and driving speeds. Firstly, a half vehicle model of the inertial suspension of the heavy vehicle based on the GH control is established. Then, the key parameters of the GH inertial suspension are optimized by the genetic algorithm and the system simulations are carried out. By comparing to the conventional passive suspension, the root-mean-square (RMS) of the vertical acceleration of the body centroid is reduced by 4.87%, and the RMS of the dynamic tire loads of the front and the rear wheels are reduced by 16.19% and 10.02%, respectively. Results show that the GH inertial suspension can effectively coordinate and improve the ride comfort and road friendliness of heavy vehicles simultaneously.

“…The traditional passive suspension has been widely used due to its low cost and simple structure. However, its single structure limits the potential for improving the vibration isolation performance of the suspension system [4][5][6]. In 2002, Professor Smith proposed the concept of inerter, and the performance of passive suspension has since been further developed.…”

In this paper, the problem of broadband vibration suppression of power-driven-damper vehicle “inerter-spring-damper” (ISD) suspension is studied. The suspension can effectively inherit the low-frequency vibration suppression effect of ISD suspension and the high-frequency vibration suppression effect of the power-driven-damper control strategy. Based on the structural method, this paper proposes four suspensions with different structures. The optimal structure and parameters are obtained by using pigeon-inspired optimization. The results show that, based on the optimal structure, the Root-Mean-Square (RMS) of body acceleration and the RMS of suspension working space are reduced by 23.1% and 6.6%, respectively, compared to the traditional passive suspension. The influence of the damping coefficient on the dynamic performance of the power-driven-damper vehicle ISD suspension is further studied. The vibration suppression characteristics of the proposed suspension are simulated and analyzed in both the time domain and frequency domain. It is shown that the power-driven-damper vehicle ISD suspension can effectively reduce vibrations across a wide frequency range and significantly improve body acceleration and suspension working space, thereby enhancing the ride comfort.
