显性动力分析中定义摩擦参数 EDCGEN, Option, Cont, Targ, FS, FD, DC, VC, VDC, V1, V2, V3, V4, BTIME, DTIME, BOXID1, BOXID2 Specifies contact parameters for an explicit dynamics analysis. OptionLabel identifying the contact behavior (dictates the meaning of V1 through V4). AG? —? Automatic general contact.ANTS? —? Automatic nodes-to-surface contact.ASSC? —? Automatic single surface contact.ASS2D? —? Automatic 2-D single surface contact (applicable only with the Cont and FS arguments).ASTS? —? Automatic surface-to-surface contact.DRAWBEAD? —? Drawbead contactENTS? —? Eroding nodes-to-surface contact.ESS? —? Eroding single surface contact.ESTS? —? Eroding surface-to-surface contact.FNTS? —? Forming nodes-to-surface contact.FOSS? —? Forming one way surface-to-surface contact.FSTS? —? Forming surface-to-surface contact.NTS? —? Nodes-to-surface contact.OSTS? —? One way surface-to-surface contact.RNTR? —? Rigid nodes to rigid body contact.ROTR? —? Rigid body to rigid body (one way) contact.SE? —? Single edge contact.SS? —? Single surface contact.STS? —? Surface-to-surface contact.?TDNS? —? Tied nodes-to-surface contact.TSES? —? Tied shell edge-to-surface contact.TDSS? —? Tied surface-to-surface contact.TNTS? —? Tiebreak nodes-to-surface contactTSTS? —? Tiebreak surface-to-surface contact.ContContact surface identified by a component name [CM] , a part ID number [EDPART], or an assembly ID number [EDASMP]. If a component name is input, the component must contain nodes that represent the contact surface (assemblies are not valid for a component name). Alternatively, a part number may be input that identifies a group of elements as the contact surface, or an assembly number may be input containing a maximum of 16 parts. The assembly ID number must be greater than the highest number used for the part ID. Cont is not required for automatic general contact, single edge contact, and single surface contact options (Option = AG, SE, ASSC, ESS, and SS). If Option = ASS2D
