摘要
波导装配过程中,由于自身形状复杂及被连接结构多级装配累积误差,过程中将产生内应力,对其力学和电磁学性能产生影响。根据力学原理,建立强制装配过程的简化分析方法;然后选用某型产品波导,通过上述分析方法评估了其结构性能,并将结果与有限元法对比,验证简化计算模型的合理性。最后结合计算结果与结构参数,分析波导强制装配可行性,结果可以为波导结构强度和使用可靠性评估提供合理依据。
Due to complexity of waveguide and accumulative error in assembly,residual stress occurs in waveguide and spoils mechanical and electromagnetic property.First of all,the simplified analyzing model of forced assembly was established according to mechanical theory.Then,a waveguide in products was analyzed by the model,and results were compared with finite element method to confirm this model.Finally,feasibility of forced assembly was assessed considering calculation results and structural parameters.Results can provide a reasonable assessment to strength and reliability for waveguide.
