模拟
优化车辆振动噪声（NVH）特性的创新型软件
为了满足客户需求，早在新模型的设计阶段和对现存车型的进一步开发阶段，欧拓使用了一系列广泛的自主研发模拟软件。这些软件将汽车制造商的单独需求和欧拓的深度专业技术结合起来。
借助这款软件，欧拓对汽车的车辆振动噪声特性（噪声、振动、舒适性） 进行预测和优化，从而为汽车的减噪做出决定性的贡献。例如，欧拓开发了GOLD模拟软件，用于对汽车阻尼材料进行基于需求的开发。这一软件不仅优化了阻尼材料的体积、重量和质量，还显示了这些零件在汽车中的最佳安装位置。这使得阻尼材料和车体面板能以最佳的方式进行组合。
高性能的REVAMP和VisualSISAB软件用于汽车内部地板零件隔音消噪性能的分析、优化和验证。这些零件包括地毯系统以及舱壁、车轮罩和地板的隔音垫。设计这一软件的目的是为了实现声学特性和产品重量间的完美平衡。这使得欧拓为进一步提升汽车内部声学设计和减轻汽车重量做出了重要贡献。
欧拓开发的模拟软件还用于引擎舱零件隔热性能的计算和进一步增强，以及对材料疲劳度的测试和分析。
