| Abstract | ||
| In this research, the total torque input and output shafts were subjected to are used to formulate two differential equations using applied dynamics and fluid mechanics. The equations show that the input and output torques are a function of the constant geometrical parameters of a torque converter, including internal 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 cross flow 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 actual torque converter were measured and substituted as fixed parameters in the equations and diagrams of the variable parameters (flow between vanes and output shaft speed) were obtained. This diagram showed an increase from the beginning for the coupling phase. The simulation showed that the torque converter performs better using dense fluid. | ||
