Abstract:
The internal composition engine laboratory has an essential
device in Mechanical engineering study which is
Dynamometer. This device let students consolidate the
theoretical information in their study, but there is an essential
need to run this device again to obtain this target, but the
problem is: the mechanical coupling between engine and
generator (two main parts of dynamometer) has been broken
after few seconds of device’s running when our colleagues
tried to rehabilitate this device last year, since they chose
improper mechanical coupling to their device So, the mission
was: first step was to choose number of flexible couplings of
this device not rigid type to avoid any serious damage if
coupling break and to accommodate misalignment. Second
step was to make a comparison between them to choose the
most proper coupling to device condition. Third step was to
make a design for our chosen coupling, all these steps had
been done in the first semester and we implemented our
coupling design in second semester , run the device again and
make many experiments on it like brake power, fuel
consumption and mass fuel rate.
