Abstract
Multi-plate Clutches (MPCs) are projected for transferring the greatest amount of torque with
less heat generation. The main objective of this thesis is modeling and FEA of multi-plate
clutches (MPCs) for selecting an optimum light weighted material for clutch plate for use in
twin clutch transmission (TCT) system of green, and Light Weight Vehicles using ANSYS
Work bench software. The candidate materials; Aluminum alloy 6061, E-Glass Epoxy UD,
and Gray Cast Iron are selected based on their weight and strength, and the mathematical
model has done for each materials using Euler Lagrange‟s Equation. The 3D solid model has
done using SOLID WORK 2016. The deformation and stress analyses were considered for
both static and dynamic analysis. The static analysis were developed using fixed support on
an inactive face of a clutch in static; and dynamic analysis is done applying displacement
boundary conditions on clutch plate, and 523 rpm rotational velocity on a plate rotating with
shafts. By default, since the objective is to increase the torque transfer capacity of a clutch,
the wear analysis were done by varying the coefficient of friction and intensity of pressure,
and thermal analysis were also done considering a heat flux of 0.54W/m

at limiting
temperature of 150ºC for candidate materials. The total deformation, and maximum
equivalent stresses were evaluated by varying the compressive pressure acted upon the clutch
plate. Then comparison has been done in terms of total deformation and Equivalent stresses
of each material, and the composite E-Glass Epoxy is found to be a better Clutch material
with a lower deformation compared to the other selected materials for design of multi-plate
clutches in TCT system.
