Method for checking survival space of automobile

Abstract

The invention discloses a method for checking a survival space of an automobile. The method comprises the following steps of carrying out overall scanning on the interior of the automobile to obtain survival space 3D data, performing modeling according to the survival space 3D data to build a survival space model, importing a preset H-point calculation rule, performing calculation to obtain a current H-point position, importing crash dummy data into the survival space model to build a crash dummy model, and calibrating the crash dummy model according to the current H-point position; performingsimulation solving on the crash dummy model in the survival space model to obtain current survival space data; and judging whether the survival space data meets a standard space requirement or not, and if yes, outputting simulation data of the survival space model. According to the method, in a mode of building the model for performing space check and judgment, the cost can be effectively reduced, the calculation time is shortened, and the calculation analysis accuracy is high; and through the importing of the preset H-point calculation rule, the accuracy of the current H-point position calculation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a method for checking the living space of an automobile. Background technique [0002] With the development of the economy and the advancement of technology, the number of cars owned by urban residents is increasing rapidly, and road traffic accidents have become one of the important threats to human life safety. Therefore, how to improve the overall safety performance of automobiles has become the most important research direction for automobile engineers. [0003] For cars, the car body is an important part of the car. The car body refers to the part of the vehicle used to carry people and load goods, and also refers to the whole vehicle. The body of some vehicles is not only the driver's workplace, but also a place to accommodate passengers and goods. The car body shape structure is the body language of the vehicle, and its design will directly affect the s...

Problems solved by technology

[0004] However, the accuracy of the existing vehicle living space calibration is low, which leads to inaccurate calibration of the vehicle living space, which in turn leads to large errors in the vehicle living space, making it difficult to match seat belts and airbags with the car body
