阶次跟踪

 

为了确定在实际工作条件下,对结构的行为影响的各个因素,需要使用阶次跟踪方法进行查看。车辆上的旋转部件如发动机、轴及车轮在旋转的时候产生激振力。您是否体验过某一辆车,会在特定的车速开始发出更大的噪音及震动?这辆车肯定没有进行相应的测试,导致在特定转速下,某些部件产生高辅振动。 

通过测量旋转速度及响应(包括振动,噪声及其他),奈奎斯特、伯德和三维FFT图能够清楚的告诉我们问题产生的频率。

结构测试

 

在车辆设计过程中,所有机械零件都可以通过电脑设计,并用有限元法来确定结构的固有频率。不过,我们需要通过实验的方法来检验这些模型,并不断进行修正,通过闭环控制使之更加精确。 DEWESoft软件DeweFRF功能能够添加导入的几何模型,使用力锤或激振器测量传递函数,观看模态动画。数据可以导出至UFF格式,以进行高级后处理。

扭振测试

 

如果加速度传感器提供的是直线方向的运动信息,扭转振动过程则是基于角度的振动信息。想象一下,车辆上的一根长轴,如同其他一切结构一样,都具有线性的固有频率,该轴在一定转速下会出现较高的角向振动。要检测的轴的扭转,需要在轴的两端各安装一个角度传感器,来测量的角度差值。数据可以导入阶次跟踪,以更清楚的暂时固有频率。

数据记录

Dewesoft在汽车行业的各中数据记录应用中扮演重要角色,尤其是在研发实验室和测试设备,从各种不同信号源获取数据是我们的主要优势,我们不仅支持标准接口,如模拟、数字、计数器、CAN、GPS和视频通道,我们同时支持特殊设备,如:Genesys的陀螺仪和Kistler的车轮扭矩传感器,所有数据完全同步。

航空航天参考用户

 

电力分析

DEWESoft产品用于航空航天、航海各个方面的测试。一个最重要的应用就是电力测试。对于大型舰船来说,三相交流电源的频率一般为400赫兹甚至是800赫兹。使用DEWESoft电力分析功能,您的系统就成为一个完整的3相电力分析仪,能够处理任何网络内的任何基频,可达800赫兹甚至更高。设备能够计算功和功率,及电力品质分析中的上百个参数,如失真、有功功率、无功功率、视在功率,总谐波失真、相位等。

DEWESoft软件电力模块精确的PLL功能,能够以0.001 Hz(1mHz)的精度追踪电源的基频,这样就可以每个周期以完全相同的采样点计算有效值及电力参数,无论基频如何变化,即使是变频电源网络也没有问题。如果不能基于频率不断地监测和调整有效采样率,就不能进行真正的电力测试。

多通道分布式系统

虽然我们支持一个设备支持多个通道,但是对于复杂的运载工具,如航天飞机等,通道数量往往是不够的。因此,可以使用DEWESoft NET功能连接多台设备同步使用,组成一台多通道系统进行数据采集和分析。所有采集设备可以通过一台设备控制,这意味着设置、启动和停止等操作可以在一台设备上完成。

可以有多台客户端在线观看数据。

风洞测试

Dewesoft产品被应用于亚音速、超音速、甚至超高音速(5倍音速)的几种主要类型的风洞测试中。我们的产品能够在这些重要的测试中同时记录视频和数据信息,各种类型的物理量及不同的传感器信号都可以通过我们的设备采集下来。

分布式数据采集

对于较长的交通工具,使用分布式数据采集系统进行设计是非常重要的。DEWESoft产品非常灵活,用户可以购买多台较少通道的数据采集设备单独使用,但需要更多通道时,可以将多台设备通过网线和同步线连接在一起,构成一台多通道的采集系统。

汽车电力系统测试

电动汽车测试的一个重要组成部分就是电力测试。 DEWESoft支持50、60、400、800赫兹及16 2/3Hz及变频的电源模块的输入,非常适合此类测试应用。

碰撞测试

公共交通工具必须通过碰撞测试。 DEWESoft软件支持高速数据采集卡以及高速摄像机同步采集,是碰撞测试的完美的测试软件。

数据记录

当涉及到公共交通时,需要进行很多测量测试以确保安全性和乘坐舒适性。以火车为例,在研发阶段,需要进行多项测试,首先是轨道质量的测量,这需要根据轨道的长度布置大量传感器,进行多次重复测试,多通道分布式采集,DEWESoft NET网络采集解决方案能够完全满足你的需求。

结构分析

Structural testing

When designing the vehicle, all mechanical parts are done with the use of computer and qualified with finite element method to determine natural frequencies of the structures. However, the need to check those method is needed more than ever to produce a closed loop to correct the models that they fit the measurement results. DEWESoft provides DeweFRF add-on software to add the ability to import the geometry models, measure transfer functions with the use of either hammer or shaker excitation and see fascinating animation of the structures on the fly. Data can be easily exported to UFF format for further processing.

Order tracking

When determining how the structures behave under real operating conditions, order tracking provides the means of seeing the structural response to real life excitation. The rotating parts of the vehicle like engine, shafts or the wheels creates excitation forces on the structure. Did you ever had a car starting to rattle and shake at certain vehicle speed? This car was for sure not tested with DEWESoft and those high vibrations were result resonance frequencies of some elements at certain input frequencies. 

By measuring rotating speed and the response (in terms of vibration, noise and others) the Nyquist, Bode and three dimensional FFTs are generated on the fly giving clear picture of the frequencies having a problem.

Torsional vibration

If the acceleration sensors provides information about linear movement, torsional vibration procedure provides the information about angular vibration. Imagine a long shaft going through the vehicle. Like each structure has linear natural frequencies, this shaft will have angular natural frequencies resulting at high angular vibration at certain rotation speed. To check the bending of the shaft, we mount any kind of angular sensor on each end of the shaft and measure the angle difference. The data can be used in order tracking to give a clear indication of natural frequencies.

Dewesoft adds the power of acquiring angle based data and calculate parameters of combustion analysis (maximum pressure, MEP, heat release, temperature, knocking, combustion noise and others). The p-v and CA-scope display shows the measurement results while measuring. DEWESoft uses multi-threading technology to use the new multi-core processors for real time calculations. 

Another major advantage of CA module is that it can be used with other data sources like CAN bus, video, OBDII and time domain analog signals, all synchronized with engine data.

分布式数据采集

对于工业领域的分布式数据采集,用户往往需要非常多的数据采集设备。当谈论到数以千计的测量通道,用户往往倾向于价格低廉的专用测试仪器,而不是使用DEWESoft产品。
 
但是所有这些解决方案有一个重大的缺点 - 它们的功能有限,采样率低。当我们需要测量电压,电流或振动等动态信号时,我们需要更高的数据采样率,以及大量的在线数据处理,以获得一些关键参数。对于一些突发事件,数据必须进行高速记录以捕捉瞬态事件。

电力分析

DEWESoft软件有一个非常好的数学功能模块提供工业领域电力(电压、电流、有功、无功、总功率),电能质量(谐波,闪变)参数的测量计算。该功能可检查电源效率,以及电网对它们造成的影响和它们对电网的反馈。
 
如果您购买专业的电力仪表进行测量,所得到的参数结果是一样的,但试用DEWESoft产品的最大的好处就是,它是一个开放的整体的解决方案,也可应用于其他测试。

桥梁监控

 


 

随着桥梁结构变得更长更加复杂,桥梁监测已经变得日益重要。许多桥梁都安装了长期监测系统。
 
DEWESoft软件能够同步记录大量分布在桥梁上的数据采集系统的数据,同时也适用于其他应用。一般情况下,数据来自于应变、位移传感器和GPS传感器。

动态信号分析

动态信号分析被广泛应用于土木工程领域。还记得塔科马海峡大桥吗?由于海风与桥梁结构产生了共振,造成桥梁倒塌。进行结构和部件的静态和动态应力应变测试非常重要。

数据记录

土木工程中经常需要数采系统进行几天甚至几个星期的数据记录,并将采集的数据发回基站,系统监测结构、噪声、振动、位移、温度等参数。市场上有许多系统可以做到此类工作, DEWESoft产品的主要优势是能够同时记录高速和低速数据,同步视频信号和其他信号源的数据。
