Abstract

Abstract:

China's serious desertification leads to the urgent need to bury sand barriers to prevent wind and sand consolidation. Under more complex desert terrain, the chassis performance of sand barrier buried machinery which determines the completion of the sand barrier burying task, is the basic problem that needs to be solved in the process of desertification control. Taking the desert slope as the main application scenario, a new type of tracked sand barrier burying vehicle was designed, and the theoretical analysis of the passability of the sand barrier burying vehicle driving longitudinally and laterally on the slope was carried out. According to the actual demand, the designed crawler sand barrier burying vehicle was simulated and analyzed for the driving process on different slopes by using Recurdyn simulation software, and the slope angle was used as an indicator to analyze and evaluate the vehicle passability. The results showed that the tracked sand barrier burying vehicle could pass smoothly on 25° slope longitudinal uphill and downhill, and could drive laterally on 15° slope and crescent-shaped sand dune after the track speed adjustment. It has proved that the tracked sand barrier burying vehicle with good passability can cope with the sand barrier burying work in the complex environment of desert.

Key words: tracked, sand barrier burial vehicle, passability, stability, slope, Recurdyn multibody dynamics

摘要：

我国沙漠化严重，急需埋设沙障进行防风固沙，沙漠地形较为复杂，沙障埋设机械的底盘性能决定能否完成沙障埋设任务，是沙漠化治理进程中需要解决的基础问题。以沙漠坡面作为主要应用场景，设计一种新型履带式沙障埋设车，对沙障埋设车在斜坡上纵向和横向行驶的通过性进行理论分析。根据实际需求，使用Recurdyn仿真软件对设计的履带式沙障埋设车在不同坡面的行驶过程进行仿真分析，以坡面角度作为指标，对车辆通过性进行分析评价。结果表明，履带式沙障埋设车在25°斜坡纵向上坡和下坡均可以顺利通过，经过履带调速后可以在15°斜坡和新月形沙丘上横向行驶。该履带式沙障埋设车具有较好的通过性，可应对沙漠复杂环境下的沙障埋设工作。
