摘　　要：利用面荷载的大小和作用方向2个表征量表示作用于模型外表面的力,利用ANSYS的SFGRAD命令定义面荷载大小随位置线性变化的荷载情况,基于ANSYS的参数数组和嵌入函数定义面荷载大小随位置非线性变化的荷载情况,以覆盖于所要施加荷载表面的表面效应单元作为"管道",施加所需任意方向的面荷载。Using size and direction of the surface load as the representation of the amount of force action on the outer surface of the model, using the SFGRAD command in ANSYS to define the surface loads linear change in size with the position, based on the parameters of an array of ANSYS and embedded function to define the surface loads non-linear change in size with the position, by the use of surface effect unit t as a ＂pipeline＂ and cover it on the outer surface of the model to impose the surface loads in any direction.

关 键 词：面荷载 ANSYS 荷载情况 表面效应单元
