摘要
相比于传统金属材料测量臂,复合材料测量臂具有比重低、抗蠕变性能好以及强度高等多方面优势。为了能够充分发挥碳纤维复合材料的高比刚度和高比强度等特点,针对某型号测量臂结构开展了力学和热变形性能的研究。先使用有限元分析软件对复合材料测量臂在一端受力作用下的应力以及位移进行了计算分析,然后对测量臂在稳态下的热变形进行了计算分析。通过设计不同铺层方案,研究了铺层方法对测量臂性能的影响,得到了适合实际生产需要的铺层方式,最终形成了满足设计需求的碳纤维复合材料测量臂结构设计方法。
Compared with the traditional metal material measurement arm,the composite material measurement arm has the advantages of low specific gravity,good creep resistance and high strength.In order to give full play to the high specific stiffness and high specific strength of carbon fiber composites,this paper studied the mechanical and thermal deformation performance of a certain type of measuring arm structure.Firstly,the finite element analysis software was used to calculate and analyze the stress and displacement of the composite measuring arm under one end of the force,and then the thermal deformation of the measuring arm under steady state was calculated and analyzed.By designing different layering schemes,the influence of layering method on the performance of measuring arm was studied,and the layering method suitable for actual production was obtained.Through this study,the structural design method of carbon fiber composite measuring arm was formed to meet the design requirements.
