摘要
以国防科技工业精密塑性成形技术研究应用中心为某履带式自行火炮设计制造的用于替换旧式钢制结构的7A04型铝合金诱导轮为例,使用UG NX软件建立几何模型,将其导入ANSYS Workbench建立有限元模型,按工况约束加载,系统地计算和分析了其应力应变分布规律、变形量、疲劳特性等。结果表明,7A04型铝合金诱导轮完全满足设计和实际工作要求,为工程试验、结构改进、优化设计和应用拓展等提供了理论依据。
Taking precision plastic forming technologyand industry for national defense technology research center for the de-sign and fabrication of a crawler self-propelled guns used to replace the old steel structure induced type of 7 a04 aluminum alloy wheel for an example, establishing geometric model by using UG NX software, importing into ANSYS Workbench to build finite element model; according to the working condition of constraint load, systematically calculation and analysis the stress and strain distribution rule, the deformation and fatigue characteristics. The results showed that the type of 7 a04 alu-minum alloy idler completely meet the requirements of design and practical work, and at the same time provided theoretical basis for engineering test, structural improvement, optimization design and application development.
