Outline
In this paper， an efficient forward collaborative design method for high-performance switched reluctance electric drive systems is proposed to enhance the power density and reduce vehicle loss under typical driving cycle conditions. Firstly， dynamic torque and radial force models of the switched reluctance motor are established. Subsequently， a loss model is developed for both the motor and the electric drive system by incorporating the gear transmission system's loss model to evaluate overall loss during typical driving cycle conditions. Finally， using mechanical， electrical， and control parameters as co-design variables and taking cycle loss， mass， torque fluctuation， and radial force fluctuation as optimization objectives， a double-layer nested optimization method is employed to optimize the design. Based on this approach， an optimized 12/8 grade switched reluctance electric drive system achieves a 19.76% reduction in total weight after collaborative optimization design. Moreover， under typical cycle conditions （CLTC-P）， the total system loss decreases by 42.45%， while overall system efficiency increases by 7.66%.
