“…Therefore, it is expected that reducing the acceleration response of the vehicle body will improve ride comfort and harshness. Some previous studies have shown that the ride comfort and harshness performance of the vehicle can be improved by optimizing the characteristics of the suspension system components [5][6][7][8][9][10][11][12][13].…”

A novel optimization technique for optimizing the damper top mount characteristics to improve vehicle ride comfort and harshness is developed. The proposed optimization technique employs a new combined objective function based on ride comfort, harshness, and impact harshness evaluation. A detailed and accurate damper top mount mathematical model is implemented inside a validated quarter vehicle model to provide a realistic simulation environment for the optimization study. The ride comfort and harshness of the quarter vehicle are evaluated by analyzing the body acceleration in different frequency ranges. In addition, the top mount deformation is considered as a penalty factor for the system performance. The influence of the ride comfort and harshness weighting parameters of the proposed objective function on the optimal damper top mount characteristics is studied. The dynamic stiffness of the damper top mount is used to describe the optimum damper top mount characteristics for different optimization case studies. The proposed optimization routine is able to find the optimum characteristics of the damper top mount which improve the ride comfort and the harshness performances together.

“…Therefore, it is expected that once the acceleration responses at the selected locations of these parts are reduced, the vehicle will achieve an improved IH. Some previous studies [2] have shown that suspension parameters have substantial effects on IH performance. In the development of a new vehicle, acceptable IH performance may be used as one of the design criteria, and all possible parameters affecting IH performance can be incorporated in the analyses.…”

This paper illustrates the development and implementation of a parameter optimization methodology to improve impact harshness (IH) of road vehicles. A full ADAMS model of a small commercial vehicle is used as the IH test vehicle. The methodology involves the use of design of experiments methods together with response surface methodology. Significant design parameters affecting IH of the vehicle are first determined by the screening experiments. Once the critical parameters are identified, they are optimized to achieve improvement in the IH by constructing response surface. The optimization results indicate that the selected suspension parameters are capable of improving IH performance of the full vehicle ADAMS model by minimizing longitudinal and vertical acceleration responses. The results also show that considerable improvement can be obtained by using the proposed parameter optimization methodology.

“…Esta abordagem permite as análises de durabilidade em estágios iniciais do programa, aumentando o nível de confiança e diminuindo o uso de protótipos. Yang et al (2006) e Duarte (2010) também utilizaram esta abordagem semi-analítica porém com o objetivo de estudar os fenômenos de ride de uma maneira precisa, minimizando as incertezas dos modelos de pneu não otimizados para tal estudo.…”
