The invention discloses a virtue instrument-based automobile simulated vibration low-frequency detection and analysis system. The system comprises two wire drawing type displacement sensors, a data acquisition card, and a computer. The sensors change displacement signals into voltage signals and output the voltage signals to the data acquisition card. The data acquisition card is connected with the computer and inputs the acquired voltage signals to the computer. By virtue of a LabVIEW software program, the computer obtains vibration signals read by the sensors, analyzes and processes the vibration signals, and finally displays the vibration signals on a user interface on the computer. The system is simple in structure and accurate in test result, and is practical and convenient. The signal analyzing and processing functions are mainly realized by depending on the software, and the software system is convenient for upgrading and maintaining. The system can detect low-frequency large-amplitude signals and has no signal conditioning circuit, thereby being simple in circuit.
Description
Technical field: [0001] The invention relates to a low-frequency detection and analysis system of automobile simulated vibration based on a virtual instrument, in particular to a low-frequency detection and analysis system of simulated vibration of a vehicle based on labview. Background technique: [0002] Vehicle vibration is an important factor that affects vehicle ride comfort and occupant ride comfort, and is also an important factor for automotive products to gain advantages in the increasingly fierce market competition. Therefore, whether the vehicle vibration signal can be processed more effectively, so as to take measures to reduce or suppress the vibration of the vehicle plays a decisive role. [0003] Traditional instruments play an important role in the field of measurement and testing, but at the same time there are many problems, such as insufficient flexibility and insufficient precision. With the continuous development of virtual instrument technology, it is ...
