Nonlinear Finite Element Modeling of Track-wheel-ground Contact

  • 摘要: 为有效预测车辆履带系统动力学响应,应用非线性有限元描述了履带、地面及负重轮之间的接触,并建立了数学模型。在增量方程的基础上采用有限单元法解决了接触边界值问题,在半圆形和等腰梯形两种路面,干沙、粘土和沙壤土3种土壤及不同负重轮位置和履带刚度条件下进行了算例分析。结果表明:车辆在等腰梯形和半圆形路面行驶时,两个边角接地压力最大;路面越软,履带接地压力越小,且越均匀;负重轮间距和沉陷量越小,履带最大接地压力越大;履带张力和负重轮上反作用力随着履带刚度的增加而增大。建立的数学模型能够合理预测履带张力变化、几何大变形和履带接地压力。
