摘　　要：在分析可变形履带轮技术现状的基础上,提出基于可变形保持架的重载履带轮行走单元技术方案.通过有限元计算,对主要部件进行了应力分析和结构优化,保证了行走单元的承载能力满足使用要求.行走单元的性能参数匹配计算结果表明,其接地比压、驱动力与制动力等性能参数能够接近于传统军用车辆的标准.Based on the analysis of the technical status of deformable track wheel,a technical scheme of heavy-load track wheel action unit based on the deformable keeping frame is put forward.The stress analysis and structural optimization of main components are carried out to ensure that the carrying capacity of the action unit meets the actual requirements by finite element calculation.The performance parameters of the action unit such as the contact pressure between the ground and the action unit,the driving force and the braking force are matched and calculated.The calculation results show that the parameters can be close to the standard of traditional military vehicles.
