——LMS Virtual.Lab快速内饰声学模块推出有效的声学多层内饰建模方法
比利时鲁文（2007年6月6日讯）：LMS国际公司宣布推出全面的建模和仿真解决方案LMS Virtual.Lab Fast Trim快速内饰声学模块，用于评定多层吸声面板的声学特性。通常这些吸声面板越来越多地用于汽车和飞机等设备，可以有效地控制车辆或者飞机的内部噪声，提高驾驶员与乘客的整体舒适性。
在高频范围内创建多层内饰声学模型具有特定的复杂性，特别是当声学解耦层，多孔层和粘弹性层表现为主要的声学品质时。LMS Virtual.Lab Acoustics新推出的快速内饰解决方案克服了这些困难，能够有效地创建多层内饰模型，达到所需的可靠性。在设定面板吸声板的顺序，并且定义各层的属性之后，快速内饰模块将整个内饰结构的传递导纳计算成频率函数。在随后的振动-声学有限元分析中，LMS Virtual.Lab Acoustics声学模块可以仿真多层内饰的性能，这些多层内饰位于车辆车身或者飞机机身的壁板与声腔之间。Fast Trim模块的仿真过程运行速度快，并且能够在高频可靠预测内部声学，这使得工程师能够更好更广泛地了解声学内饰潜在的问题。
LMS Virtual.Lab快速内饰声学模块已经被多家汽车和航天航空客户成功使用，进行多层优化。用户普遍认为快速内饰建模工具简单易用，计算速度快，分析结果准确。三菱汽车开发工程中心，CAE数字工程部经理Hirotaka Shiozaki评价道：“相比测试获得的数据，LMS Virtual.Lab快速内饰声学模块可以提供更准确的结果，而且能够以非常快的速度进行仿真过程，这使得软件更适于大型开发项目。”
