Item type:Publication, Dynamical Analysis of a Vehicle to Trailer Connection during Braking(Springer Science and Business Media LLC, 2022-08)In this paper the dynamical analysis of a vehicle to trailer connection during braking is presented. At first both the vehicles, motor vehicle and trailer are analysed as a separate vehicles, driving with same starting velocity and same braking force applied but no connection between them. Than the dynamic analysis is conducted for two types of connection, one rigid and second one with inertial brake between. The chronology of the study is to find the displacement of the vehicles as separate systems and to conduct the dynamic analysis of the two connections as a difference in the travel till zero velocity. The aim of the paper is to acknowledge the stiffness of the vehicle to trailer connection during braking - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Influence of oil quality and viscosity on some quality components of vehicle power transmission(Faculty of Mechanical engineering-Skopje, 2016-10); ; In this paper, the influence of oil quantity and viscosity on the heating state of the vehicle power transmission aggregate and the loo of power in it are analysed. Employing the design of experiments method, statistical mathematic model is determined by which the relation between the above stated components of the aggregate quality and the oil placed in it is determined. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Over-And Understeer Behaviour Evaluation by Modelling Steady-State Cornering(Analele Universităţii "Eftimie Murgu", 2012-07-21); ; This paper gives an overview of a vehicle cornering in a constant cornering radius, with constant speed. These constant values indicate steady state cornering or not changing its motion character over time. Even if the steering angle δ starting from ‘0’ (straight line driving) is reaching the constant value or the constant cornering radius, the vehicle is not following the desired path or evident is the under-steer or over-steer condition. As presented we can see the vehicle cornering, and it’s offset from the neutral driven vehicle. The vehicle is driving trough corner with greater radius. This means that the vehicle is understeered. Neutral driven vehicle is the desired arc which can be followed by vehicle with neutral steer which means that when accelerating the driver doesn’t have to change the angle of the steering wheel. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Modification of the diaphragm spring fingers beginnings and its influence on the spring stress distribution and stiffness curve(Faculty of Mechanical engineering-Skopje, 2016-10); ; ; The diaphragm spring is often used as part of the vehicle clutch assembly. The main function of the spring is to engage and disengage the pressure plate and the driven plate (clutch disk). At the time when the clutch is disengaged, the pressure plate is released and the driver can change or shift the gear. The spring is pressed with the press/release bearing from the top. The analyzed spring consists of several spokes (called spring fingers) that are set in conical shape. The spring finger beginning is the most stressed part of the spring. It acts as a lever and is subjected to numerous cycles of exploitation. In this paper is analyzed the stress distribution of the spring finger beginning. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, 3d finite element analysis of tooth contact of spur gear(Faculty of Mechanical engineering-Skopje, 2016-10); ; ; In this paper a study for determination of the maximum contact stresses in the tooth contact zone among a couple of spur gear is realized by using 3d finite element analysis. The most common damages which can be seen on tooth surface are pitting and the reason for that are contact (Hertz) stresses. In this research the analytical strength calculations and virtual testing are used for obtaining a maximum contact stresses. The results obtained are compared with the value given by two approaches, the theory of Hertz and virtual testing. The obtained results are very similar which is shown graphically in the paper. Therefore, the presented method for determination of maximum contact stresses in the tooth contact zone and the 3d finite element analysis enables obtaining improved spur gear for a relatively short time and reduces price. - Some of the metrics are blocked by yourconsent settings
