Abstract:This paper introduces two key factors in car door sash design, door sash
stiffness and door OverBend, and described their calculation points and methods in
details. Given material, two basic variables, section and door sash structure determine
door sash stiffness. Therefore this paper described door sash stiffness calculation method
from section and structure respectively, and analyzed door sash stiffness and door
OverBend by FEA software HyperMesh. Thus door sash carrying capacity and
deformation are considered in the phase of design, which make door sash design
reasonable, satisfy design request, and avoid detour.

门框是指位于汽车车门上半部分,车门玻璃周边的窗框金属件[1]。大体上门框分为三类:
①冲压成型门框结构;②滚压成型门框结构;③外门板延伸门框结构
