The invention discloses a modeling method and device of an engine frequency domain simulation model and electronic equipment, relates to the technical field of rocket engines, and aims to simplify an existing modeling method of the engine frequency domain simulation model, reduce the modeling difficulty and improve the reusability of the model. The modeling method comprises the following steps: packaging a plurality of engine components in an engine system through a modular modeling mode to obtain corresponding component frequency domain simulation models; determining an interface type corresponding to each component frequency domain simulation model according to a preset interface type division relationship; based on the interface type, determining a frequency domain interface variable parameter corresponding to each interface type in combination with a corresponding relationship between the interface type and the interface variable parameter; based on the multiple component frequency domain simulation model
