Research On Performance Test Of Full Hydraulic Braking System Of Wheeled Vehicle

A wheeled vehicle plays an important role in the economic construction and social development of today's society,the liquid pressing action as an important application of wheeled vehicle braking,plays a very important role in engineering.The hydraulic brake system of R & D and production needs to be done through hydraulic test,the hydraulic test is an important basis to test the capability and reliability of component or system,so the important parameter of hydraulic brake system test is very important.With the development of computer software and hardware technology and the emergence of virtual instrument technology,the accuracy of various test systems has been improved,and the advantages of virtual instrument in the test efficiency has been significantly reflected.Based on the analysis of the principle and performance of hydraulic brake system,design a set of hydraulic brake test system,data acquisition and display the key parameters of the hydraulic brake system of wheeled vehicle,also has data storage and alarm function.In this paper,the main contents include: 1 ? access to relevant information,to grasp the relevant content of hydraulic system testing,informed of hydraulic testing methods and methods.2?the hydraulic brake system of wheeled vehicle as the research object,analysis of the characteristics of the key components of the hydraulic brake system hydraulic braking system working principle and wheeled vehicles,based on the AMEsim simulation software,to study the characteristics of the hydraulic brake system.It provides the basis for the determination of test system and the selection of hardware.3 ? the design of full hydraulic braking test system,the principle of testing,the relevant hardware and key components of the selection of the hydraulic system for the subsequent software design to provide the hardware foundation.4?based on the LabVIEW software,the software design of the full hydraulic brake test system,the specific data acquisition,control,data storageand alarm,data processing and signal analysis and other parts of the program design.5?Based on the test system,the test steps and methods of the full hydraulic brake test system are discussed,and the test results are analyzed.
