初始设计

At the initial stage of system development and design, make the problems into core components and aspectual ones, and modularize crosscutting concerns into separate aspects, which makes system structure more clearer and makes automatic code generation possible, and also, brings convenience to the system maintenance.

而在系统开发与设计的初始阶段就将问题分解为核心组件和方面组件，并将横切关注点模块化为独立的aspect，可使系统结构更加清晰，为下一个阶段的代码生成、系统维护等工作带来便利和保障。

The governing equation of in-plane vibration of cable-restraint system is derived by means of D'Alembert principle, and then those partial differential equations are transformed into a set of ordinary differential equations by Garlerkin method. The method of Runge-Kutta integration is applied to solve the equation. The simulation analysis is made to prove that this vibration control has obvious damping effects and then the influence of cable tension, support mass, natural frequency and spring stiffness on the damping are discussed. Eventually, the approximate analytic solution of the optimum damping parameter is obtained to provide a simple and effective reference and design method for the engineers.
