The cross-country passing ability of vehicles refers to the ability to pass complex terrain and soft ground with a certain average speed under rated load.For quantitative investigation off-road vehicle through indicators, this article from the perspective of the terrain, the first seven terrain factors determined by access to information, the second of ASTER GDEM elevation data to spatial analysis, get 7 class data, finally using the principal component analysis (PCA) to 7 kinds of terrain factor has carried on the correlation analysis and factor analysis, reflect the off-road vehicle is established evaluation index of complex terrain through sexual - integrated terrain index Tr.The results show that the comprehensive terrain index Tr can account for 87.623% of the total variance of the original variable, and can integrate a single terrain factor.
