Main Article Content
The paper presents a dynamic model with 4 degrees of freedom that allows the study of pitch and swing bounce vibrations for independent suspensions. Based on this model and the results obtained, an electronic control system of a semi-active suspension can be achieved. The displacement equations obtained by applying the theorem of the center of mass and the kinetic moment are presented in matrix form. Based on this information, the influence of travel speed and the value of damping constants of the suspension shock absorbers on the amplification factors of displacement amplitudes and dynamic forces at the two wheels is studied. At the end of the paper, the results obtained on a numerical application with the data of a medium class car are presented and interpreted.

Journal author rights
In order for Romanian Journal of Acoustics and Vibration to publish and disseminate research articles, we need publishing rights. This is determined by a publishing agreement between the author and Romanian Journal of Acoustics and Vibration. This agreement deals with the transfer or license of the copyright to Romanian Journal of Acoustics and Vibration and authors retain significant rights to use and share their own published articles. Romanian Journal of Acoustics and Vibration supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in Romanian Journal of Acoustics and Vibration proprietary are defined below:
For subscription articles:
Authors transfer copyright to the publisher as part of a journal publishing agreement, but have the right to: Share their article for personal use (manuscript version); retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
For open access articles:
Authors sign an exclusive license agreement, where authors have copyright but license exclusive rights in their article to the publisher. In this case authors have the right to: share their article in the same ways permitted to third parties under the relevant user license; retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
