Abstract: This paper focuses on the design and performance simulation of a damper with torque limiter for a series-parallel hybrid light truck.The study begins with an introduction to the configura tion and parameters ofthe hybrid light truck's drivetrain system,along with the structure and working principles of the damper with torque limiter.Subsequently,the necessity of designing key parameters for the damper is analyzed to derive the torque-limiting capacity and torsional characteristics parameters.Bench tests are then conducted to validate the torsional performance of the damper. Furthermore,a simulation model is developed using AMESim software to analyze the torsional vibration suppression effects under idle and engine-start conditions.Both simulation and real-vehicle test results demonstrate that the designed damper with torque limiter significantly mitigates torsional vibrations in the hybrid truck's drivetrain system.
