“…Of late, more attention is paid to the influence of the driver seat suspension on the driver ride behavior and the development of different sear suspension systems can be found in various studies. [15][16][17][18][19][20] In this study, the dynamic ride behavior of a truck semi-trailer vehicle in terms of the power spectral density (PSD) and RMS values are investigated and the influence of the truck suspension elements on the ride comfort and road holding is presented. This paper will use a 13-degrees-of-freedom dynamic model of an articulated truck with multistage leaf springs.…”

Heavy trucks are mostly used for international transportations, with longer highways and long driving hours contributing to corresponding increases in the driver's fatigue that is related to accidents. Therefore, this study aims to improve the truck ride performance using multistage leaf springs and semi-active suspension for the driver seat. This analytical study describes the influence of the truck main suspensions on the performance indices analytically using MATLAB Simulink for different loading conditions in three case studies: fully laden articulated truck (case A), unladen truck (case B), and empty semi-trailer and a multistage leaf springs is considered after designing the main leaf spring stiffness based on particle swarm optimization (case C). This study exhibits a contribution based on the fact that changing the trailer cargo weight has considerable effects on the natural frequency of the vibration modes of the vehicle system, particularly for articulated carriage. Subsequently, the influence of the dynamic interaction of an articulated vehicle between the semitrailer and the tractor on its ride behavior has been investigated. The model has also predicted the effect of total trailer cargo on performance indices for 13 degrees of freedom model of a 6-axle articulated truck semi-trailer vehicle with a random road excitation. Additionally, a semi-active driver seat suspension based on skyhook strategy and seat passive suspension are compared in terms of the power spectral density and root mean square values. The results showed that the truck ride performance is improved significantly, and all the acceleration responses are suppressed dramatically when a designed multistage leaf spring suspension is considered in case C. The current analysis demonstrated that using specific and adjustable suspension parameters can positively enhance the riding behavior of the unladen vehicle. The results showed that the cab, tractor, and trailer acceleration improved by 22%, 21%, and 28%, respectively, which provides a comfort driving trip essentially for long distance traveling.

“…13,24,26,27 The existing ride models developed in the literature for design optimization have been based on several assumptions. To name a few, (1) they have usually used LPM models in which the secondary direction of vibration and the linkage of suspension system are ignored, 7,12,13,20,27 (2) they have only considered the dynamic response of the vehicle to the harmonic or deterministic road surface profiles, 8,15 (3) the ride analysis in the models has been normally restricted to the ride comfort corresponding to the sprung mass acceleration, 5,23 or (4) the road surface characteristics have not been involved with the ride index optimization. 4 Motivated by the observation of these issues, this study has been done to address the aforementioned issues for design optimization of the vehicle ride quality.…”

Computational multibody system (MBS) method is a practical technique utilized for modeling, simulation, and optimization of mechanical systems. In the methodology of computational multibody system, equations of motion are derived, formulated, and solved through a systematic, generalized, and well-structured computational-mathematical approach. In this paper, the computational multibody system formulation, based on the appended Lagrangian method, is implemented to establish the governing equations of ride dynamics for a nonlinear ride model that represents a versatile half-car twotrack model of a road vehicle. The input to the system is a simulated road surface model based on the ISO road surface classification. The solution of the equation of motion is obtained using the direct integration approach along with constraint violation elimination and control techniques. Following the simulation, a time-domain multiobjective design optimization procedure is performed to improve the ride quality of the model. The ride quality comprises both ride comfort and ride safety. The optimization considers relevant objective functions including vibration isolation, suspension travel, road holding, and force index. The results of work show that the proposed method could acceptably estimate the optimal values of design variables for specific road classes and vehicle driving speeds. The simulation-based ride quality optimization performed here could facilitate improvement of suspension and tyre.

“…Despite being time-consuming, they are widely used in research such as the works of Fossati et al [9] optimised it in terms of ride comfort and vehicle stability and Abdelkareem et al [10]. Seifi et al [11] used a full car ride model along with a full car lateral model to study the rollover dynamics of a vehicle. In addition, more detailed models have been developed studying the lateral dynamics of the vehicle simultaneously with the vertical ones, such as the work of Shim et al [12], Tchama et al [13] and Cao et al [14].…”

Various simulation models are used extensively for the design and the optimisation of vehicle suspension systems, as well as the application of various control algorithms in them. The selection of the most suitable model for these purposes is never explained and many times unnecessary complexity is added in them. In this respect, an assessment regarding the accuracy of the most common vehicle models is conducted. Thus, four vehicle models with various configurations are compared in terms of accuracy. More specifically, both passive and semi active suspensions are employed to the models, while the effect of adding anti-roll bars and tire dampers is also investigated. The transient behaviour of the suspension system and the overall vehicle performance are assessed in terms of ride comfort, vehicle handling and road holding using different road excitations. The results illustrate the ability of lower accuracy models to cope well and that they should be preferred most of the times. Also, anti-roll bars and tire dampers should be neglected when the ride comfort is investigated, whereas they have to be included when simulations regarding road holding are conducted.
