液压阻尼橡胶悬置（HDM）广泛应用于汽车动力总成悬置系统中，对控制汽车的噪声、振动和声振粗糙度（NVH）起着重要作用。在设计开发阶段就有必要预测高阻尼减振器的静动态特性及其对动力传动系统的隔振效果。本文研究了一种结合有限元分析和实验分析得到的参数识别的图形HDM建模方法，以预测HDM的性能。采用商用有限元软件ABAQUS中的流体-结构耦合有限元方法，通过对流体腔体的体积弹性和等效活塞面积的计算，研究了高密度流体动力学中的流固耦合问题。通过对一个典型的带固定阻尼器的HDM的静弹性和动态特性的预测以及频率响应分析，验证了该方法的有效性。该研究有助于汽车工程师提高计算机辅助系统技术在HDM和动力总成悬置系统的设计和开发。(c)2004爱思唯尔有限公司保留所有权利。
Hydraulically Damped Rubber Mount (HDM) is widely equipped in vehicle powertrain mounting system and plays an important role in noise, vibration and harshness (NVH) control of vehicle. It is necessary that static and dynamic characteristics of HDM and its effectiveness on vibration isolation of powertrain system are predicted at design and development stage. In this paper, a kind of graphic HDM modeling method integrating with parameter identifications obtained from finite element (FE) analysis and experimental analysis is investigated to predict performance of HDM. The fluid-structure interactions in HDM are explored by predictions of volumetric elasticity and equivalent piston area of fluid chamber using a kind of hydrostatic fluid-structure FE method in commercial code of ABAQUS. Predications of static elasticity and dynamic characteristics and frequency response analysis of a typical HDM with fixed-decoupler verify the effectiveness of the proposed method. This research helps automotive engineers to enhance computer-aided system technology in design and development of HDM and powertrain mounting system. (c) 2004 Elsevier Ltd. All rights reserved.
