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.

“…In the field of automobile suspension, the inerter (Inerter-Spring-Damper suspension, ISD suspension) also shows its excellent vibration isolation performance. [19][20][21][22][23] In terms of improving the ride comfort and road friendliness of heavy vehicles, Yang et al 24 studied the dynamic inertia effect of inerter-spring-damper suspension for heavy vehicle on ride comfort and road friendliness. The paper 25 investigated the potential for reduction in road damage by incorporating the inerter element into truck suspension systems.…”

With the appearance of inerter, the ISD suspension composed of “Inerter-Spring-Damper” opens up a new direction for efficient coordination of ride comfort and road friendliness for heavy vehicles. In this paper, a reference model based on the hybrid-hook damping strategy is proposed, and the mechatronic inerter is used as an active suspension force generator in the actual controlled model. Then, the coordinated control of the vehicle ISD suspension model is realized by the model predictive control (MPC) approach. The test results show that, the RMS values of the body acceleration and dynamic tire load of the controllable ISD suspension is smaller than the traditional passive and passive ISD suspension under the sinusoidal road inputs. Under the random road input, compared with the traditional passive suspension, the controllable ISD suspension has improved the RMS value of the body acceleration by 26.61%, and the road damage coefficient has been improved by 20.13%. Experiments show that the controllable ISD suspension of heavy vehicles based on the hybrid-hook damping strategy has comprehensive improvement of vehicle ride comfort and road friendliness.

“…In conclusion, the introduction of the inerter enriches the research and development of the suspension. [26][27][28][29][30] However, the mechanical ISD suspension has the problems of a large number of components, complex structure, and not easy to arrange in real vehicles. Therefore, this paper integrates the hydro-pneumatic suspension with the fluid inerter and designs a new lateral interconnected hydro-pneumatic ISD suspension, which utilizes a helical channel to connect the left and right accumulators, the piston pushes the fluid into the helical channel, and the high-speed flowing fluid stores a large amount of kinetic energy to amplify the initial inertia of the fluid.…”

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.
