尽管结构动力学的许多线性理论已经编成了许多计算机软件,但仍然存在着象反方法(模态综合法或系统鉴别法)和优化问题这样一些重要的问题.然而,对于新的研究特别是涉及大变形(例如撞击的仿真)和材料非线性的那些问题来说,非线性问题是一块肥沃的土壤.结构相互作用问题将继续是一个富有成果的研究领域,它包括流体-结构动力学以及与噪声、热场、土和电磁力的相互作用.例如,需要大于钝体非定常绕流的新知识,来使桥梁及建筑物结构在非定常风中产生的动态相互作用问题得到重大的进展.一个在应用方面很有前途的新领域是柔性结构的反馈控制理论.这个领域可以在近空间工程和机器人学方面得到发展.然而,在控制-结构领域中应该最优先考虑的是,培训出在结构动力学和控制理论方面都有基础知识和实践经验的新型研究人员.
Although many linear theories of structural dynamics have been compiled into many computer software, there are still some important issues such as inverse methods (modal synthesis or system identification) and optimization problems. However, for new research, especially For those problems involving large deformations (such as simulation of impact) and material nonlinearity, the nonlinear problem is a fertile soil. The structural interaction problem will continue to be a fruitful research area that includes fluid-structure dynamics and Interactions with noise, thermal fields, earth and electromagnetic forces. For example, new knowledge greater than the unsteady flow of a bluff body is required to make significant progress in the dynamic interaction between bridges and building structures in unsteady winds. A promising new field in applications is the feedback control theory of flexible structures. This field can be developed in near space engineering and robotics. However, the top priority in the control-structure field should be training. New researchers with basic knowledge and practical experience in structural dynamics and control theory.
