Abstract

In the vehicle industry, it is ‎required to model a Vehicle Drivetrain based on a well-recognized system and analyze the system ‎behavior with the aim to redesign or modify the system to meet different operational ‎requirements. So, this paper aimed to Design, Modelling, and Analyzing of a ‎Vehicle Drivetrain using SimDriveline. The followed methodology was divided into four steps, which are; Analysis of Variable and Simple Gear Systems‎, Analysis of Simple Hydraulic Clutch System, Modelling and Investigation of a Vehicle Drivetrain, as well as Model-based design of a simple power transmission system using SimDriveline. The results of this paper showed that in the simple gear with introducing one of the meshings there was a slight decrease in velocity and the torque was unstable and not smooth. In the variable gear, the velocity has considerably decreased wherein the torque was increased. Also, in the clutch, the pressure has increased after modifying the input signal and the engine power in the earlier times. The change was very small after changing the simple gear with variable gear in the drivetrain vehicle model which cannot be taken into consideration however, when the physical constant block has replaced by throttle there was a big effect on the engine power as well as the vehicle speed.
