摘　　要：变速器壳体零件刚度是设计的关键。以FEA变形量数据为依据,增强壳体轴承孔等关键受力区域的刚度,通过MASTA计算其所支撑轴的挠度也相应降低。通过台架试验验证,降低了同步器磨损量,解决了同步器脱档现象,为提升换档可靠性起到重要作用。Major function of transmission cases is containing and supporting internal components such as bearings, gear assemblies, which need endure high shock loads. Stiffness is very important for canes. Through FEA analysis data, stiffness of canes is strengthened, and through MASTA calculation, deflection of shafts is reduced. It is very important to enhance the shifting reliability of the transmission.
