SMAT2008V32STUDY ABOUT AUTOMOTIVEROLLOVER DYNAMICSFlorentin POPESCU, Vasile CAMPIAN, Diana C. THIERHEIMER,Victor OTAT, Walter W. THIERHEIMERAbstract: The problem of kinematical, dynamical and mathematical models is considered to characterize thedynamical behaviour of vehicles on curvilinear movement. In this particular case were considered the elements thathave a great influence on this dynamic behaviour of vehicles, as: geometry of guiding wheels, constructive andfunctional features particular to each front stabilization system of the vehicles, as well as the road micro profile thatinfluence in particular the linear movement. The differential equation described in here was solved using the Laplace’smethod and the experimental works was carried out using a BMC acquisition system. The theoretical and experimentaldata comparison confirms with good accuracy the hypothesis made on the study of vehicle’s stabilization system.Keywords: BMC acquisition system, curvilinear movement, dynamical behaviourFlorentin POPESCU, drd.eng., University of Craiova, Faculty of MechanicsVasile CAMPIAN, prof.dr.ing., Transilvania University of Brasov, Faculty of MechanicalEngineering, E-mail: campian@unitbv.ro, 0268-413000Diana C.

SMAT2008V33THE OPTIMIZATION OF THE MAINTENANCE ACTIVITY FOR THEDIRECTIONAL CONTROL SYSTEM OF THE MOTOR VEHICLE BASEDON THE RELIABILITY INDICATORSAuthor: PhD student Eng. Horia Marcel SOTOCOvidiu Vasile CampianAbstract: The efficiency and quality of the maintenance activity within the restoration process of the technicalsystems’ function capacity depends mostly on assuring spare parts supplies and on planning as exact as possible themaintenance and repair works during the motor vehicles’ operation period. In the essay is presented a method based onthe application of the reliability indicators for the rational establishment of the spare parts supply to be replaced duringthe maintenance works that should guarantee both small costs, as well as minimum time for the immobilization of thevehicles during this process. The way to apply the proposed method is presented within the directional control systemof a 5,8 tone lorry.Keywords: optimization, maintenance, directional control system, utility car, lorry, reliability indicators,operational time.Ovidiu Vasile CAMPIAN, prof.dr.ing., Transilvania University of Brasov, Faculty ofMechanical Engineering, E-mail:.c.ovidiu@unitbv.roSMAT2008V34THE INFLUENCE OF THE PRODUCTION AND EXPLOITATIONFACTORS UPON THE RELIABILITY OF THE MOTOR VEHICLES’DIRECTIONAL CONTROL SYSTEMAuthor: PhD student Eng. Horia Marcel SOTOCOvidiu Vasile CampianAbstract: The insurance and the increase of the reliability of a technical system depends mostly on thedetailed knowledge of all projection, production and exploitation factors’ influence upon the technical state of a vehicleduring the operation process. In the essay there are presented the causes that may determine the decrease of thereliability of a vehicles’ directional control system and the technical and technological measures that can be taken to reestablishits safe operation.Keywords: influence, reliability, lorry, utility car, directional control system, operational capacity,performance.Ovidiu Vasile CAMPIAN, prof.dr.ing., Transilvania University of Brasov, Faculty of MechanicalEngineering, E-mail:.c.ovidiu@unitbv.ro21
