Application of Multi-objective Optimization for Optimization of Half-toroidal Continuously Variable Transmission

Among different goals defined in vehicle design process, fuel consumption (FC) is one of the most important objectives, which significantly has taken into account lately, both by the customers and vehicle manufacturers. One of the significant parameters which impacts the vehicle FC is the efficiency of vehicle's power train. In this paper, a half-toroidal continuously variable transmission (CVT...

Design of Continuously Variable Transmission (CVT) with Metal Pushing Belt and Variable Pulleys

Nowadays, automakers have invested in new technologies in order to improve the efficiency of their products. Giant automakers have taken an important step toward achieving this objective by designing continuously variable transmission systems (CVT) to continuously adapt the power of the engine with the external load according to the optimum efficiency curve of e...

High-performance simulations of continuously variable transmission dynamics

The paper describes a parallel computational model simulating continuously variable transmission (CVT) dynamics. A specific feature of the CVT model is the combination of relatively small problem sizes (about 1000 unknowns) and high computational costs (up to several weeks of sequential code computations for a thirty seconds simulation period). The main source of computational complexity here i...

Dynamics Analysis and Control of a Holonomic Vehicle with a Continuously Variable Transmission

This paper presents kinematic and dynamic analysis of a holonomic vehicle with continuously-variable transmission. Four ball wheels, independently actuated by DC motors, enable for moving the vehicle in any direction within the plane and rotating it around its center. The angle between the two beams holding the balls can be changed to alter the gear ratio and other dynamic characteristics of th...
