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.
