摘要
提出一种新型轮履复合变体轮—双横臂悬架模块的设计概念,建立了该悬架模块的运动学分析模型。采用空间解析几何方法得到变体轮悬架系统的数值模型,以某型全地形UTV为基础改装变体轮,利用MATLAB对变体轮———双横臂悬架模块进行仿真。并通过变体轮轮式下的ADAMS仿真结果和轮式下的数值解进行对比,验证了模型的正确性。最后,利用该数值模型对变体轮展开为履带式下的悬架系统运动特性进行了分析。仿真结果显示,将变体轮直接改装在UTV上容易出现履带节磨损,履式下转向困难等问题。为变体轮悬架系统进一步的优化设计提供参考。
The design concept of a new wheel-track variant wheel-double wishbone suspension mode is proposed here,and the kinematics analysis model of the suspension module is set up.Based on space analytic geometry,the numerical model of variant wheel-double wishbone suspension system is established.By refitting the variant wheel to a certain type of all terrain farmer truck （UTV）,a simulation for variant wheel-double wishbone suspension model is carried on by using MATLAB.And the correctness of the model is verified by comparing the simulation results of variant wheel in wheel style with ADAMS.By using the kinematic numerical model,the analysis of the motion characteristics of variant wheel in track style is implemented.Simulation results show that wear of crawler belts and difficult steering in track style is prone to appear when the variant wheel mounted directly on the UTV.It can provide references for optimization of the variant wheel suspension system.
