【摘要】 随着现代汽车工业的发展 ,广大汽车生产厂家迫切需要在汽车设计生产过程中进一步控制汽车振动和噪声水平。快速寻找并识别主要的噪声源和振源 ,有效地对汽车噪声和振动测量结果进行分析处理 ,得到切实可行并具有良好经济性能的降噪方案就成为其中最首要的前提性工作。这使得汽车噪声与振动测量分析系统开发的设计指标日益复杂 ,综合性越来越高。使用面向对象技术来实现汽车噪声与振动测量分析系统的开发 ,可以缩短系统的开发周期 ,降低系统开发的成本 ,它强调系统开发过程中软件的重用性、开放性和可扩充性 ,使系统开发走上了柔性化、集成化和经济化的道路更多还原

【Abstract】 With the developing of the automobile industry, how to control the noise and vibration level of the products come to urgently for the auto factories during their developing and producing period. Finding out the main noise source and vibration source quickly, analyzing the noise and vibration signal effectively, contriving a noise descending algorithm reasonable and economical become the first and most important job for auto corporations. At the mean time it complicate the developing guide line of the noise and vibration testing system. With object oriented technology, we can develop the noise and vibration testing system in a short time and with a low cost. The object oriented technology emphasizes the circulation, exoteric and expandable of the codes. It enables us developing the system follow a flexible, integrable and economical procedure..更多还原
