中文摘要:针对履带式车辆黏弹性悬架阻尼缓冲件具有的大变形、严重非线性及不可压缩等特性,建立起300 kW履带式拖拉机黏弹性结构动态接触3D有限元模型。经有限元计算和分析,得到其应力集中区域、“热点”分布和主要破坏方式及其位置等重要特性,并提出了改进建议。经对模型与试验数据的观察发现,二者具有较好的一致性。本文的研究方法和结果可为高性能黏弹性悬架的研发提供参考。

Abstract:A 3D dynamic contact finite element method(FEM) model was established on the bassis of the characteristics including large deformation, serious nonlinearly, incompressibility, and so on, for damping buffers mounted on viscoelastic suspensions used in 300 kW crawler tractors. Through FEM computations and analyses, some important characteristics, such as the stress concentration regions, the distribution of temperature “hot spot”, their principal destruction ways and position, and so on, were obtained, and some improvement suggestions were made. It is found that their values are well consistent bewteen the model and tests by comparison. The methods adopted and results obtained in this paper may be helpful for the research and development of the high-performance viscoelastic suspensions.
