The invention discloses a Bladed fan load processing system based on a Matlab and particularly relates to fan BLADED load calculating preprocessing and postprocessing software based on MATLAB development. The system is divided into four modules, namely, the Bladed load calculating preprocessing module, the Bladed conventional load postprocessing module, the Bladed component load processing module and the Bladed load working condition self-evaluating module. The common load preprocessing and postprocessing process is automated through a calculation procedure, the manual processing time is shortened for load calculating personnel, the repeated work of the load calculating personnel is reduced, and the load preprocessing and postprocessing efficiency is improved. A load calculation model file based on a self-defined working condition table can be automatically generated, the extreme and fatigue load of each component can be automatically extracted and output, the design load of each component is output based on design and procedure generalization and summarization of each component of the complete machine system, the working condition is automatically evaluated and judged through the procedure according to the evaluation indexes of various working conditions, and whether all working condition simulation models and simulation time sequences are normal or not is fast judged.
