“…Aiming at the structural vibration caused by flywheel commutation of the ball screw inerter, Li et al 22 studied the dynamic model and equivalent electrical model of the ball screw inerter with mechanical diodes in 2021. At present, the vibration isolation advantage of ISD suspension has been confirmed in various fields such as the vehicle suspension, 23,24 the building vibration isolation, 25,26 and train suspension. 27,28 Then, the advantage of the inertial suspension in reducing the road damage of heavy vehicle was studied by Liu et al 29 and Yang et al 30 In addition, in 2017, Hu et al 31 adopted the SH control strategy to improve the ride comfort of the vehicle inertial suspension.…”

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.

“…Te research illustrates that compared with the vibration suppression performance of traditional suspension, the performance of vehicle ISD suspension of many layouts is much better [9,10]. Under diferent road excitations, the dynamic characteristics of suspension are studied, and the results illustrate that the vibration suppression performance of vehicle ISD suspension is very superior [11]. Two types of vehicle ISD suspension layouts are designed and analyzed in the frequency domain, and it is shown that the vibration in the ofset frequency bands of the body resonance can be suppressed by vehicle ISD suspension [12].…”

In this paper, the vehicle ISD (inerter-spring-damper) suspension and power-driven-damper control strategy are combined to the suspension design, and the power-driven-damper semiactive ISD suspension is proposed. The dynamic models of the passive suspension S1 and two semiactive ISD suspensions S2 and S3 are established. Based on the port-controlled Hamiltonian theory, the power-driven-damper semiactive control strategy is designed by analyzing the power transfer of suspension S3. Then, the parameters of the two models are optimized by the particle swarm optimization algorithm, and the optimization results show that the suspension S3 has better performance. The influence of the semiactive damping coefficient, the spring stiffness, and the inertance on the vibration suppression performance is investigated based on the suspension S3. The effect of parameter perturbation on power-driven-damper semiactive vehicle ISD suspension illustrates that the designed semiactive vehicle ISD suspension has better ride comfort in a wider range frequency and good robust performance.

Aim to balance the ride comfort and handling stability of vehicles and improve suspension performance, this paper presents a novel lateral interconnected hydro-pneumatic “inerter-spring-damper” (ISD) suspension integrating a hydro-pneumatic suspension and a fluid inerter, which realizes the lateral connection of the suspension through the inerter. The equivalent mathematical model of the lateral interconnected ISD suspension is established; the 15-degree-of-freedom (DOF) model of the vehicle is built in AMESim, and the key parameters are optimized by genetic algorithm. The response characteristics of the novel hydro-pneumatic ISD suspension and traditional hydro-pneumatic suspension under pulse and random input are comparatively analyzed. The lateral interconnected hydro-pneumatic ISD suspension prototype is developed and tested on the bench. The simulation and test results prove that the proposed new suspension structure has a more effective shock absorption performance than the traditional hydro-pneumatic suspension. Overall, the novel hydro-pneumatic ISD suspension better consider to the ride comfort and handling stability, and the structure is simple, compact, and easy to deploy on practical vehicles.
