驾驶舒适性已经成为一项评价汽车性能的指标,振动噪声直接影响到舒适性水平。而汽车领域多种振动噪声是由于共振引起的。本文采用通过安装动力吸振器的方法,改善频响函数在共振区域的表现,以有效改善共振问题。通过使用LMS Test Lab软件,对不同状态的减振对象(不安装吸振器与安装吸振器)进行模态测试,求得它们的频响函数。通过对比频响函数在共振区域的表现来直观反映改善效果。 Driving comfort has become an indicator of car performance and vibration noise directly affects comfort levels. A variety of vibration and noise in the automotive field is due to resonance. In this paper, through the installation of dynamic vibration absorber method to improve the frequency response function in the performance of the resonance region, in order to effectively improve the resonance problem. Through the use of LMS Test Lab software, modal tests on different vibration damping objects (without vibration absorbers and vibration absorbers installed) to obtain their frequency response functions. By comparing the performance of the frequency response function in the resonant region to visually reflect the improvement effect.
