Thermal Analysis of Double Mass Flywheel Secondary Flywheel
IOP Conference Series: Materials Science and Engineering, 2020 Abstract To solve the problem of thermal overload failure in dual-mass flywheel (DMF), we performed temperature field calculation and thermal analysis of the secondary flywheel in DMF. Based on the results of this analysis, we performed thermal stress analysis on the secondary flywheel.
