摘要
针对连续纤维增强金属基复合材料涡轮轴结构力学性能计算及优化设计问题,基于复合材料宏观叠层结构理论及经典层合板理论,开展复合材料涡轮结构力学性能计算。通过建立与试验件相同结构的有限元模型,边界条件及载荷与试验条件完全一致,计算涡轮轴结构节点应变、周向位移响应及其承载能力,并分析轴结构径向截面危险位置。将计算结果与试验结果对比分析,验证涡轮轴结构力学性能计算方法及失效分析的有效性。基于上述研究,建立某型发动机涡轮简化轴结构,采用遗传算法,优化铺层角度、铺层厚度及金属层厚度影响因素,最终在保证轴结构承载能力基础上,达到减重效果。
For continuous fiber reinforced metal matrix composites turbo-shaft structure mechanics performance calculation and optimization design problems,it based on the macroscopic composite laminated structure theory and the classical laminated plate theory,calculating mechanics performance of composites turbo-shaft structure calculation.The finite element model with the same structure as the test pieces can be established,and it kept the no differences to experiment on boundary conditions and load conditions,calculated the strain,axial displacement response and carrying capacity of turbine shaft structure node,then analyzed of the radial shaft structure interface risk position. The calculation results are compared with the test results to verify the validity of the calculation method and failure analysis of the structural mechanical properties for the turbo-shaft. Based on the above research,modeling simplify the shaft of a certain type engine turbine,based on the genetic algorithm,optimized the factors of layer angles,layer thickness and thickness of metal layer influencing,finally on the basis of guaranteeing the shaft structure capacity,achieve weight loss results.
