| 摘 要： | 以车用增压器JP60涡轮叶轮为研究对象,基于最优化设计的原理,在不改变叶型及流道并保证涡轮叶轮结构强度的基础上,利用ANSYS优化设计模块及APDL语言编制用户程序,以涡轮叶轮重量最小为目标对增压器涡轮叶轮进行了减重结构优化.在此基础上考虑涡轮叶轮铸造和装配工艺等因素,确定了新型的减重涡轮叶轮结构,使得涡轮叶轮重量减少了6.9 %.优化后的涡轮叶轮结构不仅节省了材料的消耗,同时使得涡轮增压器转子质量分配进一步趋于合理,有助于提高增压器轴系的机械效率和可靠性.强度校核及寿命分析表明,优化结果满足使用要求.

| Abstract: | Based on the principle of optimization design, structure optimization of JP60 turbine wheel was carriedout using optimization module of ANSY and APDL in order to obtain minimum turbine weight when retaining. The original blade profile and flow passage and keeping enough structure strength of turbine wheel. Considering assembly technique and cast requirement, a new lightening structure was determined, and the weight of modified turbine wheel decreased 6.91% compared with original turbine wheel. The modified turbine wheel saved material, consumption and resulted in more reasonable mass distribution between turbine wheel and compressor impeller. The study result provided useful reference for engineering application of turbocharger. |
