investigation and dynamic analysis of torque converter operation

in this research, the total torque input and output shafts were subjected to are used to formulate twodifferential equations using applied dynamics and fluid mechanics. the equations show that the input andoutput torques are a function of the constant geometrical parameters of a torque converter, includinginternal and external diameters of vanes, angle and length of vanes, cross section area between vanes,density of fluid, and inertia of the torque converter turbine. the variables in these equations were crossflow between vanes and output shaft speed. the equations were solved using matlab software.simulation in matlab uses two inputs and two outputs. eighteen physical parameters from an actualtorque converter were measured and substituted as fixed parameters in the equations and diagrams of thevariable parameters (flow between vanes and output shaft speed) were obtained. this diagram showed anincrease from the beginning for the coupling phase. the simulation showed that the torque converterperforms better using dense fluid.
