摘要
根据某型矿车前轮轮距加宽80 mm的要求,利用ADAMS虚拟样机技术,对该车双横臂扭杆弹簧前独立悬架进行建模,仿真对比分析轮距加宽前后的悬架的前轮参数性能。以最小轮胎侧向滑移量绝对值为目标函数,对前轮轮距加宽后的悬架性能进行优化分析,结果轮胎侧向滑移量绝对值的最大值由原来7.1 mm减小至2.9 mm,同时,其变化范围也由原先的-0.9～7.1 mm缩小至0.2～2.9 mm。得到优化加宽后的悬架运动学特性符合设计要求,可有效降低轮胎磨损的结论。
Based on the requirements of a certain type of mine vehicles front wheel distance widening 80 mm, deals with the modeling of double wishbone torsion bar spring front suspension by ADAMS virtual prototyping technology, and comparative analysis includes suspension performances before and after widening tread by simulation. Finally, the minimum of absolute tire lateral slippage is designed as objective function, and suspensions are optimized after widening front wheel distance. The absolute maximum of tire lateral slippage amount reduces from 7.1 mm to 2.9 mm, the same time, and its change range is from the original -0.9-7.1 mm down to 0.2-2.9 mm. It concludes that suspension kinematics characteristic meet design requirement after widening front wheel distance, and reduce effectively the tire wear.
