新人！！螺栓接触中的螺纹从面间隙区域是什么意思？？？

啊啊啊啊啊

想要通过定义螺栓参数来模拟螺栓，但是不知道参数设置里的Clearance region on slave surface是什么意思？？应该选哪里？？？

应该是螺纹间隙吧

Generating the contact normal directions for a threaded bolt connection automatically Alternatively, for a single-threaded bolt connection the contact normal directions for each slave node can be generated automatically by specifying the thread geometry data and two points used to define a vector on the axis of the bolt/bolt hole. The vector should be oriented to point from the tip of the bolt to the head of the bolt when in tension and from the head to the tip when in compression.

Input File Usage:                  
*CLEARANCE, SLAVE=surface_name, MASTER=surface_name, TABULAR, BOLT
half-thread angle, pitch, major bolt diameter, mean bolt diameter node number or node set label, clearance value, coordinates of points a and b on the axis of the bolt/bolt hole

Repeat the second data line as often as necessary.

ABAQUS/CAE Usage:        
Interaction module: contact interaction editor: Clearance: Initial clearance: Computed for single-threaded bolt or Specify for single-threaded bolt: clearance value, Clearance region on slave surface: Edit Region: select region, Bolt direction vector: Edit: select axis, Half-thread angle: half-thread angle, Pitch: pitch, Bolt diameter: Major: major bolt diameter or Mean: mean bolt diameter
