它还包括一个可视化的输出绘图仪和动画,以及车辆的描述,预装控制输入数据库,并模拟运行。
ThedatabaseinitiatedinArcSimcontainsparametersforapresetcombination:
theM916A16-wheeldrivertractorandtheM870A23-axlesemitrailer.
在ArcSim发起的数据库包含一个预设的组合参数:
M916A16轮驱动拖拉机和M870A23轴半挂车。

仿真模型参数。
因此,您可以添加新的参数,内置的数据库,根据需要为代表的3轴拖着一个3轴半挂牵引车作出任何车辆。

此外,ArcSim数据库包括输出文件运行了“离线与科研计算机程序”。
所有输出,作出是否脱机或与包括模型制造,可以被视为具有内置的动画和绘图仪。
AlthoughArcSimhascapabilitiesforswitchingbetweenmodels,parametersetsandinputs,thecurrentversioncontainsasinglebaselinesimulationprogram,derivedfromtheTruckSimsoftwaredevelopedatUMTRIandsoldcommerciallybyMechanicalSimulationCorporation.
虽然ArcSim已切换模式,参数设置和投入能力,当前版本包含一个基线仿真程序,在UMTRI从软件开发的TruckSim所得和出售机械模拟公司商业化
Asnewmodelsaredeveloped,theycanbeaddedtothepackagebyusinganexitingmenucommand.
随着新车型的开发,它们可以被添加到该程序包使用一个现有菜单命令。
