一、前言随着科学技术的进步和交通运输事业的不断发展,振动噪声已成为汽车设计中必须考虑的重要因素之一。其中,车身振动和车室内的振动共鸣音与车身结构有密切关系。为了减少噪声,提高乘座舒适性,迫切需要对车室内的振动噪声和车外噪声采取措施。下面将国外对振动、振动共鸣音、车外噪声三方面与车身结构的关系及大客车车身特有的一些振动噪声问题作一介绍。 I. Introduction With the progress of science and technology and the continuous development of transportation, vibration and noise have become one of the important factors that must be considered in the design of automobiles. Among them, the body vibration and vibration of the interior vibration of the car body structure and are closely related. In order to reduce the noise and improve ride comfort, it is urgently necessary to take measures against the vibration noise inside and outside the car. The following foreign foreign vibration and vibration of vibration, noise outside the car body structure and the relationship between the three parts and bus body vibration noise some unique to make an introduction.
