To improve the minimum time handling and stability of a vehicle, multi-objective optimization of vehicle suspension was studied. Taking a vehicle with double wishbone front suspension and multi-link rear suspension as an example, the vehicle model was built based on ADAMS/Car. Through double-lane change simulation test, it was found that the vehicle understeer was too large. The main factors influencing understeer in the suspension were analyzed. It was determined that the height of the suspension roll center, the equivalent cornering stiffness, and the roll steering coefficient were taken as the optimization objective. Combined with insight sensitivity analysis on hard point coordinates and bushing stiffness, the optimization variables were determined. According to the evaluation index of minimum time handling and stability, the performance before and after the optimization was analyzed and contrasted by ADAMS. The result showed that the evaluation index of driver burden, the evaluation index of rollover hazard, the evaluation index of vehicle side-slip hazard, the evaluation index of dynamic, the evaluation index of tire road holding capacity, and the evaluation index of responsiveness were all decreased, which indicated that the minimum time handling and stability of a vehicle was improved after optimization.

The current geopolitical situation in the Europe is forcing some countries to modernize the equipment and armaments of their armies and to prepare for response to potential threats. It is difficult to assess the advantageousness and quality of military logistics vehicles to be purchased when there are different perceptions of the functionality of the product among future users, and in particular when the quality assessment tools are not perfect and the available and statutory quality assessment tools are hardly used in tendering procedures. This article presents the methodology for the evaluation of military logistics vehicles in public procurement. The proposed methodology allows comparing military logistics vehicles on the basis of economic and technical criteria and assessing the needs of different users.

Inerter, a new type of mass element, can increase the inertia of motion between two endpoints. In order to study the dynamic inertia effect of inerter–spring–damper suspension for heavy vehicle on ride comfort and road friendliness, the inerter–spring–damper suspension is applied and its mechanism is studied. This paper establishes a half vehicle model of inerter–spring–damper suspension for heavy vehicle. The parameters of inerter–spring–damper suspension for heavy vehicle are optimized by multi-objective genetic algorithm and system simulations are carried out. The parametric influence of different spring stiffness, damping coefficient, inertance, and load on suspension performance is also studied. The simulation results demonstrate that the centroid acceleration and pitch angular acceleration are improved by 24.90% and 23.54%, respectively, and the comprehensive road damage coefficient is reduced by 4.05%. The results illustrate that the inerter–spring–damper suspension can decrease the vertical vibration of vehicle suspension especially in low frequency and reduce the road damage. The analyses of suspension parameters perturbation reveal their different effect laws of the different wheels on vehicle ride comfort and road friendliness, which provide a theoretical basis for setting parameters of inerter–spring–damper suspension.
