1.Because of the limitation of the traditional linear vehicle-following model, in consideration of speed relations among adjacent vehicles, four vehicle-following models are set up, they are the vehicle-following models under the following four conditions: the leading and following vehicles at the same speed, lower speed of the following vehicle than leading vehicle, higher speed of the following vehicle than leading vehicle when the leading vehicle keeps speed and slows down.
摘要分析了传统车辆跟驰模型的局限性,建立了考虑前后车速度关系的车辆跟驰模型:前后车以相同速度匀速行驶时的跟驰模型;前后车以不同速度匀速行驶,后车速度小于前车速度时的跟驰模型;前后车以不同速度匀速行驶,后车速度大于前车速度,当前车速度不变时的跟驰模型和前车减速时的跟驰模型。
2.By calculating to compare its computational speed of the mold filling software on foundry using different slack factors and iterative times and verify the precision of simulation with benchmark test by Birmingham University in the Great Britain.
通过实际计算比较了松驰因子w和迭代次数n对铸造充型过程模拟软件中所使用的超松驰迭代法的计算影响,通过统计计算时间来比较其计算所耗时长,和与英国伯明翰大学所做的标准验证实验对比以验证其模拟精度。 得出在固定的迭代次数下,松驰因子w对计算速度和计算精度有较大的影响,而迭代次数在大于临界值时则影响不大。
