Reducing vehicle
weight without compromising performance becomes an area which is important to
improve fuel economy and reduce vehicle emissions. The possibility of reducing
unsprung mass in a vehicle has led to many investigations of weight
optimization studies of axle and wheel-end components. Therefore, structural
design of a torque plate, which is one of the main parts of a Z-cam drum brake
used in heavy-duty vehicles, is carried out by using topology optimization and
finite element analyses. Firstly, finite element analysis of the original
torque plate is conducted to determine critical stress levels and locations.
Secondly, topology optimization is carried out on the original torque plate for
specified loading conditions. Taking redundant volume and manufacturability
constraints into account a new torque plate design is composed. Finally, finite
element analysis is repeated to verify the final design. A significant decrease
in stress level is accompanied by considerable reduction in casting and machined
part masses by 11.9% and 12.2% respectively.
