针对CACC (cooperative adaptive cruise control)车队在弯道行驶的安全性和稳定性问题,提出一种V2X (vehicle to everything)环境下基于MPC (model predictive control)算法的弯道区域CACC车队行驶轨迹跟踪策略.首先,分析CACC车队在弯道区域的行驶工况以及纵向平衡问题,并基于牛顿第二定律构建车辆在弯道行驶的车辆动力学模型;其次, CACC车队基于V2X技术实现车车之间状态信息的实时交互,并以基于车辆运动学的MPC算法为基础,引入可变间距的车队安全距离控制模型,提出一种适用于弯道区域的轨迹跟踪模型;最后,通过二次规划进行模型求解.实验分析结果表明:V2X环境下的CACC车队在弯道行驶过程中面对不同的行驶工况能够不同程度地保证车车之间的安全性、稳定性以及驾乘人员的舒适性,有效验证了所提V2X环境下基于MPC算法的弯道区域CACC车队轨迹跟踪策略的可行性.

目的解决轻薄铝合金电池包顶盖拉延成形过程中的工艺质量问题。方法采用Autoform软件对顶盖拉延成形过程进行仿真分析,在单一条件下分别研究压边力、冲压速度、凹凸模间隙以及摩擦因数对顶盖拉延成形规律的影响。以最大减薄率和最大增厚率为评价指标,通过对以上4个工艺参数进行正交实验优化,且采用正交综合评分法分析实验数据,得出影响评价指标的4个因素的主次关系(冲压速度>压边力>摩擦因数>凹凸模间隙)以及最优工艺参数。结果最优工艺参数如下:冲压速度为1000 mm/s,压边力为800 kN,摩擦因数为0.12,凹凸模间隙为1.26 mm。采用最优工艺参数进行拉延成形实验验证,实验后测量实物顶盖,实际最大减薄率为14.3%,最大增厚率为8.6%。与仿真值比较,顶盖的实际最大减薄率误差为8.9%、最大增厚率误差为7.5%,实际值与仿真值之间的误差合理。结论在实际生产中,该工艺参数优化的方法能够为后续轻薄铝合金顶盖的生产制造提供有价值的指导。
