Summary

摘要

ArcSimisafreesetofintegratedcomputertoolsforsimulatingandanalyzingthebrakingandhandlingofa6-axletractor-semitrailer.

ArcSim一种免费的综合性的计算机应用软件，它用于模拟和分析6轴式半挂车的制动性和操纵性。

ThesoftwarerunsunderWindows9xandWindowsNT.Itcontainsafullyfunctionalvehicledynamicssimulationprogramthatcansimulateresponsestoarbitrary（user-defined）steeringandbrakinginputs,onflatorinclinedgroundsurfaces.

该软件在Windows9x和WindowsNT系统下运行。

它包含了一个功能全面的车辆动力学模拟程序，这个程序可以模拟车辆在平坦的或倾斜的路面上任意的（用户定义的）转向和制动输入。

Italsoincludesaplotterandanimatorforvisualizingoutputs,andapreloadeddatabaseofvehicledescriptions,controlinputs,andsimulationruns.

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。

Thesimulationmodelsareparametric.Therefore,youcanaddnewparameterstothebuilt-indatabaseasneededtorepresentanyvehiclemadeofa3-axletractortowinga3-axlesemitrailer.

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。

Inaddition,theArcSimdatabaseincludesoutputfilesforrunsmade"off-line"withresearchcomputerprograms.Alloutputs,whethermadeoff-lineormadewiththeincludedmodel,canbeviewedwiththebuilt-inanimatorandplotter.

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。
