“…This innovation enhances the electromechanical analogy theory by introducing mechanical analogs to electrical capacitance, leading to the development of the 'inerter-spring-damper' (ISD) suspension system [13,14]. Research indicates that the ISD suspension exhibits superior vibration isolation [15][16][17]. Shen [18] employed a fractional-order electrical network to further enhance the vibration performance of ISD suspension.…”

This study introduces a novel hydro-pneumatic inerter suspension (HPIS) system for engineering vehicles, aiming at enhancing ride comfort and handling stability. The research focuses on addressing the limitations of conventional suspension systems by incorporating an inerter element into the vehicle suspension. The unique aspects of HPIS, such as nonlinear stiffness and nonlinear damping characteristics of the hydro-pneumatic spring, are explored. Firstly, a half-car dynamic model of the HPIS suspension is established, and an improved simulated annealing algorithm is applied to optimize the suspension parameters. Then, we compare the dynamic performance of different HPIS structures, specifically parallel and series layouts. For practical analysis, a simplified three-element HPIS suspension model is used, and the suspension parameters are optimized by a simulated annealing algorithm at speeds of 10 m/s, 15 m/s, and 20 m/s. Key findings reveal that compared to the traditional suspension system of S0, the front and rear suspension working space of S1 decreased by 40%, 40.1%, 40.2% and 30.7%, 30.8%, 30.9%, while with the body acceleration and pitch acceleration deteriorated by 3.1%, 3.2%, 3.3% and 63.4%, 63.8%, 64.0%. However, the S2 can improve all the dynamic performance and offer better ride comfort and handling stability.

“…The performance of the gear rack inerter and ball screw inerter was tested, the results showed that the performance of the inerter was greatly affected by friction factors in a low-frequency band [12]. A classification process for finding effective branches of a mechanical network was described, and a design method for a passive mechanical network of ISD suspension was proposed [13,14]. Electromechanical similarity theory and mechanical network synthesis theory were used to determine the structure of ISD suspension.…”

The “inerter-spring-damper” (ISD) suspension system is a suspension system composed of an inerter, spring, and damper. To study the ride comfort and stability of the vehicle by using the ISD suspension system, a vehicle model with ISD suspension is established in this paper. The vehicle model including vertical, pitch, roll, and yaw motion of the vehicle body. Based on the vehicle model, the differential equation of motion with ISD suspension is obtained. The dynamic responses of the ISD suspension system are investigated by using different road excitations. At the same time, the influence of coupled excitation and single excitation on the vibration reduction performance of the ISD suspension system is studied. Then, the dynamic responses of ISD suspension and passive suspension are compared, and the improvement of comprehensive vibration reduction performance of ISD suspension system is quantitatively analyzed. The numerical results illustrate the ISD suspension has the optimal vehicle speed under different road excitations, and the comprehensive vibration reduction performance of the ISD suspension is the best when driving at the optimal vehicle speed. Under different types of road excitation, ISD suspension shows excellent comprehensive vibration reduction performance. ISD suspension is more suitable for vibration reduction of complex roads than that of a single road.

“…An ISD vibration isolation system can comprise other more complex vibration isolation systems, so it is very meaningful to individually analyse an ISD vibration isolation system. Jiang and Smith conducted a series of studies on ISD vibration isolation systems and proposed a passive mechanical vibration network 12 and a design method with an inerter. 13,14 As research work in this area has progressed, applications of inerter in general engineering practice has become more extensive.…”

“…[24][25][26][27] Actually, an article 28 illustrated nonlinear inertance calculation method of ball-screw inerter, in which friction, nominal radius, lead, contact angle, ball radius and number of balls were considered. Inspired by some researches on nonlinear vibration isolator where used positive and negative stiffness, [29][30][31][32] compared to the previous methods used to calculate transmissibility, 12,[15][16][17][18][19] this reported study expressed the mass (M ¼ m þ b) as a complex mass (M* ¼ m þ bj) and re-established several dynamic equations for a vibration isolation system with ball-screw inerter to deduce transmissibility. The experimental results of this study showed that the transmissibility calculations in this study were closer to the experimental results than those previously reported, especially in a frequency band of 10 Hz.…”

The wide application of the ball-screw inerter for vibration isolation has made it increasingly important to precisely determine the vibration transmissibility of the isolation system. In this reported work, the transmissibility of a vibration isolation system containing an inerter was predicted by using a complex mass M* in the calculations. The reported theoretical analysis showed that in the design of the type II inerter-spring-damper and inerter-rubber vibration isolation systems, the inertance-mass ratio must be less than twice the damping ratio to achieve improved vibration isolation performance when designing the system. To validate the findings, experimental tests were conducted on the type II inerter-spring-damper and inerter-rubber vibration isolation systems with ball-screw inerter. The experimental results showed that, based on M*, the transmissibility of these two systems was close to the experimental results, which illustrated the rationale for using M*. The results of this reported study will help facilitate the parameter design and performance analysis of a vibration isolation system with an inerter.
