The dynamic performance matching method and analysis software (hereinafter referred to as the software) for mechatronic hydraulic systems of construction machinery can automatically form a complete system model based on user selection of power components for the entire machine, and predict the performance of the construction machinery during operation as well as the power output and heat generation of each component. The software can be applied in various stages of development of construction machinery products such as parameter selection, performance matching, fault diagnosis, experimental assistance, etc., and has been successfully used in the new product development of Shantui Construction Machinery Co., Ltd.
