Abstract:
An integrated optimization method that comprehensively considers draping factors such as fiber reorientations and cutting of layers is proposed for designing CFRP B-pillar reinforcement with a variable thickness. A laminate parameterization scheme, the local shared layer parameterization scheme (LSL-PS), is developed to parameterize the physical composition of laminates with variable-thickness. Kinematic draping simulations and preform designs are introduced to evaluate fiber reorientations and eliminate manufacturing defects. The optimization design of the B-pillar reinforcement is integrated

All parties favour the half-bridge current-doubling rectifier circuit due to its advantages: small output current pulsation, low switching voltage stress, and high anti-unbalance ability.

This paper carefully analyzes the existing magnetic integration schemes. Combined with the characteristics of low-voltage and high-current DC converters, the secondary winding in this paper adopts the form of one turn to further reduce the loss so as to adapt
