摘要
首次应用数字仿真方法对步行轮式气垫车在软地面行驶过程进行了动态数字仿真,应用系统分析方法建立了该系统的运动微分方程,提出了运输生产率、运输效率、垫升比功率、等效运动阻力系数和升沉加速度最大值等性能评价指标,确定了目标函数。对步行轮轮轴相对车体的位置进行了优化,并对软地表进行了随机数字仿真,编制了步行轮式气垫车在软地面行驶过程的大型动态仿真程序包。
For the first time the dynamic digital simulation on travelling procedure of walking-wheel type air cushion vehicle passing through a soft ground has been done by using digital simulation method. Several performance evaluation targets, such as kinematic resistance coefficient, maximum rise-and-fall acceleration have been set up with the position of the axis of walking-wheel in relation to the body of vehicle optimized. Finally, in this paper, a large simulation program of the travelling procedure of walking-wheel type air cushion vehicle is elaborated.
