Abstract

The invention relates to the technical field of vehicle fire-proof safety, and particularly relates to a vehicle fire test system and method. The system comprises a test platform, a test instrument assembly and a control device, wherein the test platform is used for bearing a fire test sample vehicle; a monitoring device arranged at a fire-proof weak position of the sample vehicle is mounted in the sample vehicle and is used for monitoring related data of the sample vehicle in the burning process; the test instrument assembly comprises an ignition device arranged below the sample vehicle, a multi-channel data collection device connected with the monitoring device and used for collecting monitoring data of the monitoring device, a heat acquisition device arranged above the sample vehicle and used for collecting heat released in the burning process of the sample vehicle, a timer for determining test time of a fire test and a thermal imager for acquiring a flame temperature of the samplevehicle in the burning process; and the control device is connected with the test instrument assembly. The vehicle fire test system and method disclosed by the invention are low in cost, high in speedand good in reproducibility and can accurately control flame burning strength and burning time.

Description

technical field [0001] The invention relates to the technical field of automobile fire safety, in particular to an automobile fire test system and method. Background technique [0002] In the process of automobile research and development, in order to verify whether the fire performance index of the whole vehicle meets the research and development expectations and to discover the potential fire prevention capability of the developed vehicle in time, it is necessary to conduct a fire test to verify the vehicle. During the test, the status of the test sample vehicle is confirmed , test device layout, personnel execution actions and operating procedures have strict requirements. Whether the test personnel strictly follow the rules to carry out the test directly determines the validity of the test results. During the process, due to the uncertainty of the test environment and test equipment, the automobile fire test is not easy to control, the reproducibility is poor, and the re...
