The invention discloses a parametric computer modeling
system for a universal main girder of a crane, which includes a front man-
machine interface part and a background core calculation part, wherein the background core calculation part includes a welcome interface module, a main
data structure initialization module, a
graphics Interface module, button command module, parameter output module, data inspection module, dynamic help module,
clock module, the front man-
machine interface part includes parameter guidance module,
input selection module, parameter input module, operation command selection module, dynamic help module ,
clock display module, the characteristics of the present invention have powerful main girder parameter modeling capabilities, perfect
data error checking capabilities, good human-computer interaction, good compatibility and portability, and provide guidance for the design and manufacture of large crane girders Opinions, improve the design efficiency and
processing quality of the main beam, and reduce the cost of the main beam product.
