Abstract:An electromagnetic-mechanical fully variable valve actuation（EMVVA） was proposed to achieve continuous adjustment of valve timing and lift during the engine operation. To precisely assess the performance of the EMVVA， a simulation model was developed using the multi-physical field coupling method. According to the motion laws and dynamics characteristics of mechanical transmission， a geometric and multi-body dynamics model of mechanical transmission was constructed. Based on the finite element method， an electromagnetic field model， a temperature field model and a structural mechanics model of the electromagnetic drive of the fully variable valve actuation were established. The electromagnetic， temperature， dynamic characteristics of the variable valve actuation were researched. Moreover， a multi-physical field coupling model of fully variable valve train was established by coordinating model of different computational scales. Through the integration of the multi-physical model and optimization algorithms， the research achieved significant performance enhancements， including a 27.6% reduction in actuation power consumption， 16.4% improvement in electromagnetic drive angular acceleration characteristics， 41.9% suppression of torque ripple amplitude， along with 31.0% decrease in equivalent inertia moment within the mechanical transmission chain.
