摘要
文章利用声学边界元理论,使用Virtual.Lab软件分析发动机的辐射噪声;然后在计算结果不满足目标值的情况下提出了优化方案,并对方案进行仿真分析;最后通过试验验证了优化方案的可行性。通过仿真分析的方式,缩短开发周期,节约了研发成本。
In this paper,the radiated noise of engine is analyzed by use of acoustic boundary element theory and Virtual.Lab software.Then the optimization scheme is proposed when the result of calculation does not meet the target value,and the scheme is simulated and analyzed.Finally,the feasibility of the optimization scheme is verified by tests.By means of simulation analysis,the research development cycle is shortened and development cost is saved.
