Method and system for automatically generating envelope of moving part of automotive suspension

The invention discloses an automatic generation system and method for an envelope of an automotive suspension moving part (CA-FSET for short), and the method comprises the steps: carrying out the visual graphic processing of a movement track of a suspension through a computer technology, and enabling a moving mechanism device to obtain the coordinate parameters of a hard point, needing to generate the envelope, of a current moving part; setting a suspension corner stroke for the driving command function based on the custom array function; an array function is defined according to the sweeping track of each part, the array function calls a driving command function to drive the movement mechanism device to move, so that the hard point of the target part moves according to the sweeping track, and the copying and calling unit copies and pastes the 3D data needing to generate the envelope. And the envelope generation unit obtains the data hard point coordinate value of the moving part according to the coordinate p
