4. Dynamic design of mechanical structure and system The dynamic design of <br>machinery is based on the dynamic characteristics of mechanical products and the predetermined design goals. The design, prediction, modification and re-analysis of machine-hang products are performed to determine the structural shape that conforms to the static and dynamic characteristics of the product , Dimensions and other physical and geometric parameters until they meet the design requirements of the dynamic characteristics of the product structure system. Mechanical dynamic design involves many disciplines such as machine vibration theory, computer technology and modern design methods. So far, a complete dynamic design theory, method and system have not been formed. Many problems need to be further studied.

4. 机械结构与系统的动态设计<br>机械动态设计是依据机械产品的动态特性与预定的设计目标,进行机杭产品的设计、预测、修改与重分析,确定符合产品的静态、动态特性的结构形状、尺寸等物理与几何参量,直到满足产品结构系统的动态特性的设计要求。机械动态设计涉及机被振动理论、计算机技术和现代设计方法等诸多学科范畴,至今还没有形成完整的动态设计理论、方法与体系,|许多问题尚需进一步深入研究。
