Abstract: The flywheel housing is an important part connecting the engine and the gearbox. Whether its structural design is reasonable will directly affect the natural frequency of the whole powertrain, and the strength of the flywheel housing will also affect the life of the engine. Based on ANSYS Workbench in the engineering design stage, this paper conducts modal analysis, static strength analysis under extreme working conditions and fatigue analysis under daily service conditions for the new developed cast aluminum flywheel housing, and then makes interpretation and later verification of the analysis results, which providing a reference for flywheel housing design and improvement, effectively shortening the product development cycle and saving research and development costs.

Key words: flywheel housing; modal analysis; strength check; vibration noise; natural frequency

摘要: 飞轮壳是连接发动机与变速箱的重要零部件,其结构设计是否合理会直接影响到整个 动力总成固有频率和发动机寿命。文章基于 ANSYS Workbench 在工程设计阶段对新开发的动 力系统铸铝飞轮壳进行模态分析、极限工况下的静强度分析以及日常服务工况下的疲劳分析, 并对分析结果进行解读和后期验证,可有效缩短产品的开发周期和降低研发费用,为飞轮壳 设计和改进提供参考。
