Design of Test System for Performance of the Car Vacuum Booster Based on Virtual Instrument Technology

Abstract:

Article Preview

Vacuum booster is an important assembly part of the auto brake system.It influences the driving security directly so that it must be tested whether it reaches the design target and the related standards before leaving factory or in servicing in order to eliminate the driving danger.The virtual instrument based on LabVIEW is a kind of advanced technique with powerful analytical ability, flexible configure and rich tool modules providing many advantages for engineering test in virtue of computer and digital signal processing.The thesis based on its advantage to teat the performance of vacuum booster in a simulated work conditions, which is based on the National Standard of GB12676-1999, QC/T 307-1999 and QC/T 308-1999.The test system has been designed with the integration of hydraulic pressure control technology, data acquirisition technology, electro mechanics and virtual apparatus.The result indicated that the test system was reliable and the data acquirisition was accurate.Especially, the system could simulate the instance of auto in the state of long slope braking or frequent braking and has certain superiority compared with existing equipment.
