This research is focused on determination of optimum working conditions of a vessel power consisting of diesel engines, a twin input gearbox and a controllable pitch propeller. Combined dual input gearbox as an intermediate member of the power train is run by two diesel engines. This gearbox consists of gears, multi disk input clutches, and output. One diesel engine acts as master and works as primary driver, and the second diesel is used as auxiliary during excess power needs. Gearbox model includes nonlinear elements like multi disk clutch and gear backlash. Diesel engines are modeled as power sources controlled by PID control of power lever for maintaining the desired speed. Tejson-... 

For optimum designing of dry friction clutch, we should taking into account a lot of parameters, in order to the clutch have good efficiency in torque transmission and power train. These parameters include: the type of friction plate and the mechanical properties, Clutch geometry, diaphragm spring and its ability to make pressure. In this project, the goal is the analysis of effect of different parameters in clutch's temperature distribution and effect of these issues in torque transmission. In next step, the clutch's temperature distribution analyzed by changing the friction plate (ceramic), pressure applied and relative round in order to gain optimum properties of clutch. These works done...
