复合材料层合板装配精度影响因素研究

受制造能力的限制,零件加工和装配过程难免存在误差,因此产品的装配精度难以保证。不同于金属材料,复合材料具有各向异性的特性。因此,复合材料产品的装配精度更加难以控制。针对复合材料产品装配精度难以保证的问题,分析了复合材料层合板装配精度影响因素。采用有限元仿真分析方法,通过将同一批零件进行编号并重新配对组合,分析不同零件配对组合方式对装配精度的影响;对于由多个零件组装而成的装配顺序可调整的产品,分析不同装配顺序对装配精度的影响。研究表明,零件的不同配对组合方式和装配顺序都会对装配精度产生影响,因此,在实装前进行装配精度预判,选择最优的零件配对组合方式和装配顺序对提高复合材料产品的装配精度是非常必要的。

Research on Factors Inlfuencing Assembly Accuracy of Composite Laminates

Errors cannot be avoided in the process of machining and assembly because of the restriction of the manu-facturing ability, hence the assembly accuracy of products cannot be guaranteed. Different from the metal material, com-posite material possesses anisotropy characteristics. Therefore, the control of the assembly accuracy of composite laminates is more difficult. For the problem that it is difficult to guarantee the assembly accuracy of composite laminates, the factors influencing the assembly accuracy of composite laminates was analyzed. After the parts machined in the same batch were numbered and recombined with other parts, the effect of the combinations of different parts on the assembly accuracy was analyzed using finite element method (FEM). For the assembly composed of multiple parts which can be assembled in dif-ferent orders, the effect of assembly sequence on the assembly accuracy was also analyzed. The research realizes that both the different combinations of parts and the different assembly sequence have impacts on the assembly accuracy of the com-posite laminates. Thereby, it is very important for improving the assembly accuracy of composite laminates to predict the assembly accuracy and to optimize the combination and assembly sequence before the parts are assembled.
