33-50 ANALIZA PRIN ÎNCERCAREA RIGIDITĂȚII SUSPENSIEI CU ARCURI ELICOIDALE ȘI AMORTIZOARE HIDRAULICE ÎN CAZUL AUTOVEHICULULUI BMW E46 318D 115 CP 265 Nm LIMUZINA PE UN STAND CONTROLAT ELECTRONIC

ANALYZIS THROUGH TESTING OF SUSPENSION’S HARSHNESS WITH HELICAL SPRINGS AND HYDRAULIC DAMPERS IN THE CASE OF BMW E46 318D 115 HP 265 Nm LIMOUSINE MOTOR VEHICLE ON A ELECTRONICALLY CONTROLLED TEST BENCH
The present research work highlights the measurements made on suspension, vibrations and harshness aspects on BMW E46 318D vehicle limousine using an electronically controlled test bed. Many companies and laboratories seek pragmatically directed research in automotive fields and knowing such thing here is developed an experimental study on a real street car. In this case it is analyzed the behavior of suspension system concerning harshness, showing that the mass placement influences the suspension system behavior.
The problem of suspension influences is a serious one and the objective of the present study is to gain results and an insight of the oscillations damping process. The research methodology and specific objectives are oriented to bring the specific parameters and the research goal to open access.

33-47 CERCETĂRI PRIVITOARE LA ÎNCERCAREA RIGIDI-TĂȚII SUSPENSIEI CU AMORTIZOARE HIDRAULICE ÎN CAZUL AUTOVEHICULULUI BMW E46 320D 150 CP 320Nm LIMUZINA PE UN STAND CONTROLAT DIGITAL

RESEARCHES CONCERNING THE SUSPENSION’S HARSHNESS TESTING WITH HYDRAULIC DAMPERS IN THE CASE OF BMW E46 320D 150 CP 320NM LIMOUSINE MOTOR VEHICLE ON A DIGITAL CONTROLLED BENCH
This research paper outlines the tests made on suspension, vibrations and harshness aspects in correlation with BMW E46 320D motor vehicle limousine on a digital controlled testing bench. Economic units and workshops look positively toward utilitarian directed research from applied modules and academic activities (especially in automotive fields). Thus is the case with the characteristics of suspension system’s harshness when comes to the motor vehicles, specifically the BMW. Taking the problem seriously the aim of the present research paper and the targeted system is suspension and its harshness when tested in a specialized workshop. The research method and specific objectives are directed to reach these specific goals and the study expectations from academic community.
