Abstract: In order to improve vehicle’s trafficability in the desert, based on the analysis of the desert soil parameters and the theory of traficability of crawler vehicles on soft ground, a LY352J desert crawler transport vehicle equipped with triangular track shoes was developed. This vehicle can carry out personnel and material transportation, vehicle traction, and winch tration operations, mainly composed of key parts such as triangular track shoes, winch and cab. Through theoretical analysis and calculation, the parameters of each key component andh traction traficability of desert crawler transport vehicle on soft desert ground were determined. Creo software was used to build a virtual prototype, and RecurDyn（Recursive Dynamic） dynamic simulation software was used to simulate the optimal tension selection, straight driving, climbing, and turning of vehicle crawler. The results showed that, under the condition of 45% vehicle weight, the optimal tension of the track was 26. 46 kN; under the condition of 26. 46 kN track tension（45% vehicle weight）, it could ensure the smooth operation and good performance of the vehicle; the maximum slope obtained by uphill simulation was 30°； in the steering dynamics simulation, the steering stability of the vehicle on the road was better, but it was easy to lose stability when turning, and it would appear lateral inclination. At last, the experiments of straight running, longitudinal climbing and turning of test vehicle were carried out in test site, and it was verified that the vehicle had good trafficability when actually walking in the desert terrain, and can overcome the drawbacks of wheeled transport vehicles sinking in sand, meeting the requirements of current desert terrain transportion operations.
