IDIADA实验室或试验场可进行噪声和振动测量,整车级或系统级和子系统级的测量均可执行。问题评估和解决工作一般在实验室进行。
半消声室可用于所有不需要外界噪声和振动事件干扰的测试类型。消声室与其建筑内的其他空间完全隔离,消声室内配备的底盘测功机能够重现试验场上的驾驶工况。消声室墙壁和天花板上安装的吸音尖劈结构,可以最小化噪声反射,模拟自由声场工况。消声室空间已通过ISO 26101:2017标准认证,可根据UN Regulation 138 (AVAS, 最小噪声) 和 UN Regulation 28(喇叭噪声)标准执行测量工作。
消声室主要特性:
模态分析测试台架放置在安静房间内,适用于车身饰件和白车身模态分析、系统及子系统测量。除此以外,还可根据具体要求,将模态分析的测量设置放大到商用车体的尺寸。
因此,小到单一零部件,如刹车片和仪表板,大到商用车驾驶室和整个巴士结构,我们的团队均具有丰富的分析经验。
四立柱测试台架一般用于将已知的振动工况输入到车轮,可以考察多种类型的车辆问题,如车身共振评价、系统本征模态或异常评价。
