摘要
本文给出在自由界面部件模态综合中应用移频技术的理论依据,证明了适当地选择移频值才能简化计算过程和保证良好的精度,并利用工程算例作了验证.
A theory basis for the free-interface component mode synthesis by means of the spectrum shift technique is presented in this paper, It demonstrates that the technique may be employed in the component level to reduce the calculation of the residual attachment modes and achieve great accuracy, provided the shift value is properly selected. Results of two examples versfied the derived conclusion.
