摘要
高速履带车辆履带脱轮问题是一项非常复杂的工程技术问题。为降低履带车辆在行驶过程中履带脱轮发生概率,以力学理论为基础,分析了履带脱轮时诱导齿与负重轮的相互作用关系,并以ADAMS软件为仿真平台建立了可测试履带从负重轮脱出难易程度的多体动力学模型。模型充分考虑履带、诱导齿及负重轮设计参数,利用正交试验设计方法开展履带刚度特性、诱导齿及负重轮设计参数对履带脱轮影响的仿真研究,仿真结果表明,不同的设计参数对履带脱轮影响的灵敏度不同。将试验数据进行神经网络拟合,对拟合后的表达式进行GA算法寻优,找到防止履带脱轮的因素最优值,使履带系统的运行稳定性得到了显著提高。
The track off-wheel problem of high-speed tracked vehicle is a very complicated engineering and technical problem.In order to reduce the probability of track off-wheel,based on the mechanics theory,the interaction between the induction teeth and the road wheel during track off-wheel was analyzed,and a multi-body dynamics model was established to test the difficulty of track disengagement from the road wheel using ADAMS software as the simulation platform.The model fully considered the design parameters of track and road wheel,and used the orthogonal experimental design method to carry out the simulation research on the influence of track stiffness characteristics,induced teeth and load wheel design parameters on the track off wheel.The simulation results show that the sensitivity of different design parameters on the track off wheel is very different.The experimental data were are fitted by neural network,and the expression after fitting was is optimized by GA algorithm to find the optimal value of factors preventing the track from running off the wheel,which significantly improved improves the running stability of the track system.
