The performance of wet multi-disc clutches is strongly affected by frictional behavior under varying thermal conditions. This study presents an experimental and numerical investigation of torque transmission characteristics at different pressures and temperatures. An experimental setup was used to measure torque under controlled operating conditions, enabling analysis of the influence of thermal variation on clutch performance.

A numerical model based on standard torque relations was developed by incorporating temperature-dependent friction coefficients and clutch geometry. The model was applied to predict torque values corresponding to the experimental conditions. The results show that torque increases with applied pressure due to higher normal force between friction surfaces, while an increase in temperature beyond moderate levels leads to a reduction in torque due to decreased lubricant viscosity and friction coefficient.

The numerical results are in good agreement with experimental data, with percentage error within acceptable limits. The study demonstrates that thermal conditions play a critical role in clutch performance and confirms the reliability of the developed numerical model for predicting torque behavior in wet multi-disc clutch systems.
