Title    The design of mechanical system of performance testing platform for the train brake device
based on Labview
Abstract
As China enters the era of high-speed train,the concern about the safe operation of the high-speed train is continuous increasing.The braking system plays a crucial role in the safe operation of trains,so the quality and reliability of the braking system must undergo a rigorous test.This paper aims to design a digital test platform to simulate the process of train braking,and detect key components of the braking system based on related test systems as well,which ensure that the braking system can meet the requirement of necessary technology data,thereby ensuring the safe operation of trains.
The virtual instrument technology is the main development direction of modern testing techniques,the test platform based on virtual instrument technology has many advantages compared to traditional testing methods,such as faster testing,simpler operation,low cost,more flexibility and more adaptability.The test paltform primarily based on the virtual instrument technology recurrence actual braking action through the pneumatic and mechanical systems,collect corresponding parameters of test items refered by technical reqiurements through a variety of sensors ,and process the data by computer and software.The contents of hardware system design also include:strength and stiffness checking of test platform and critical mechanical components,the design of mechanical and pneumatic system,calculation and selection of linear bearings,motors,sensors,and pneumatic components.
