Abstract
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:
The present invention relates to a kind of simulative automobile vibration low frequency based on virtual instrument and detect analytic system, particularly a kind of simulative automobile vibration low frequency based on labview detects analytic system.
Background technology:
Automobile vibration is the key factor that affects Vehicle Driving Cycle ride comfort and passenger riding comfortableness, is also the key factor that automobile product gets the mastery in day by day fierce market competition simultaneously.Therefore can more effectively process automobile vibration signal, thereby take measures targetedly to reduce or the vibration that suppresses automobile just plays a part very important.
Traditional instrument plays an important role in measurement field tests, but also exists problems simultaneously, and as inadequate in dirigibility, precision is not high enough.Along with the development of virtual instrument technique, it just progressively replaces all kinds of traditional instruments of measurement and control area.
Summary of the invention:
The invention discloses a kind of simulative automobile based on virtual instrument vibration low frequency and detect analytic system, adopt specific stay-supported type displacement sensor, can collect low frequency large amplitude signal, therefore modelled signal modulate circuit not makes circuit reduction.
Technical solution of the present invention:
A kind of simulative automobile vibration low frequency based on virtual instrument detects analytic system, comprise two stay-supported type displacement sensors, data collecting card, computing machine, it is characterized in that: a kind of automobile vibration based on virtual instrument detects analytic system, comprise two stay-supported type displacement sensors, data collecting card, computing machine, it is characterized in that: two stay-supported type displacement sensor bodies are installed on the fixed mount of vertical two-freedom simulative automobile shaking table, its bracing wire is fixed on the vibration output shaft of simulating vibration table, sensor is converted to displacement signal after voltage signal, output to data collecting card, data collecting card is connected with computing machine, by the voltage signal input computing machine collecting, computing machine is by LabVIEW software program, obtain the low-frequency vibration signal that sensor reads and carry out analyzing and processing.
The present invention is simple in structure, practical and convenient, and test result is accurate.Digital Signal Analysis and Processing function mainly relies on software to realize, and software systems are convenient to upgrading and are safeguarded.Low frequency large amplitude signal can be detected, and no signal modulate circuit, circuit is simple.
Accompanying drawing explanation:
Fig. 1 is that the simulative automobile vibration low frequency that the present invention is based on virtual instrument detects analytic system structured flowchart.
Embodiment:
Simulative automobile based on virtual instrument vibration low frequency detects an analytic system, as shown in Figure 1, adopts respectively MPS-S-P type stay-supported type displacement sensor, and MPS-010602 Multifunctional USB data acquisition card is equipped with the computing machine of LabVIEW software.
