汽车动力总成是汽车的主要振动激励源之一,对汽车的乘坐舒适性有很大的影响,合理的汽车动力总成悬置系统的设计可以明显的降低汽车动力总成和车体的振动。 - Abstract : based on analyzing the fault mechanism for fire - loss bush of the main bearing in nd2 diesel engine , the paper firstly presents the relations between exciting source of vibration and fire - loss bush fault ; then introduces experiments on vibration detection and diagnosis of the engine ; finally , the results show that the condition of fault for the main bearing can bediagnosed through detceting the vibration of engine base surface
文摘:在对nd2机车柴油机滑动主轴承烧瓦故障机理分析的基础上,阐述了柴油机的振动激励源及特征量与烧瓦故障之间的关系,并介绍了柴油机的振动监测与诊断的试验研究,试验结果表明:利用机座外表面的振动特性的变化可以诊断出机车柴油机主轴承的故障状态。 - Its principle is : a laminated structure ( beam or plate ) with delamination consists of undelaminated region and delaminted region which can be divided to upper and lower parts . when a low - amplitude and high - frequency excitation has the frequency close to some part ' s natural frequency , this part will resonate and certain amount of mechanical energy will convert to heat so that the delaminated region ' s temperature exceeds greatly that of the undelaminated region . therefore the delamination can be located by means of infrared thermograph
其原理是具有脱层的层合材料构件(梁或板)包含脱层区域及未脱层区域,脱层区域分为上下两部分,若对层合材料构件施加小振幅、高频率的振动激励,当激励频率恰好接近其中一部分的固有频率时,该部分就会产生共振响应,部分机械能将转化为热能,使脱层区域的温度远高于未脱层区域,借助红外热像仪即可显示出脱层的位置。
