Modelling and validation of a novel continuously variable transmission system using slider crank mechanism

Modelling and Optimization of Toroidal Continuously Variable Transmission in ECE Driving Cycle

In the present study, the aim is to optimize full and half toroidal continuously variable transmission (CVT) in order to minimize the vehicle fuel consumption (FC) in ECE driving cycle. First, the model of both CVTs’ efficiency is presented. The control strategy of CVTs speed ratio based on minimizing the vehicle FC is introduced, and the algorithm of calculating the vehicle FC is shown. Afterw...

Pareto Optimal Multi-Objective Dynamical Balancing of a Slider-Crank Mechanism Using Differential Evolution Algorithm

The present paper aims to improve the dynamical balancing of a slider-crank mechanism. This mechanism has been widely used in internal combustion engines, especially vehicle engines; hence, its dynamical balancing is important significantly. To have a full balance mechanism, the shaking forces and shaking moment of foundations should be eliminated completely. However, this elimination is usuall...

Mechatronic Redesign of Slider Crank Mechanism

Mechatronic design efforts have been and continue to be heavily investigated in the development of robotic manipulator arms. However, little effort has been devoted to mechatronic redesign of traditional two-dimensional mechanisms which mechanical engineers get exposure to when they study subjects such as kinematics and mechanism design. In this paper a feasibility study for controlling the mot...

Control of a Continuously Variable Transmission System

This paper proposed control strategies for the modern mechatronic Continuously Variable Transmission (CVT) System using three different techniques; The Ziegler-Nichols, Linear Quadratic and Pole-Placement methods. The results of the system responses of the designed control schemes were successfully simulated using MATLAB. Comparing the results showed that controller implemented using the Pole-P...
