Summary:The invention relates to the technical field of composite materials, in particular to a pressure optimization method and device for a fiber preform forming process, equipment and a medium. The method comprises the following steps: firstly, constructing an initial yarn mesoscopic model, then respectively carrying out compaction simulation on the initial yarn mesoscopic model by adopting multiple groups of pressures to obtain a target yarn mesoscopic model under each pressure, then respectively combining the target yarn mesoscopic model under each pressure with a preset resin matrix model to obtain a curing model under each pressure, and finally, carrying out compression simulation on the curing model under each pressure. And finally, based on the curing model under each pressure, the pressure of the fiber preform forming process is optimized. Therefore, according to the technical scheme, the influence of the yarn mesoscopic model on curing deformation under different pressures is revealed by using a numerical
