Abstract

The invention relates to a method for establishing a virtual prototype of a hydraulic excavator. The method comprises the following steps of: establishing a dynamic model of the hydraulic excavator in dynamic simulation software ADAMS (Automatic Dynamic analysis of Mechanical System), and establishing a multiport valve hydraulic system model of the hydraulic excavator in hydraulic system simulation software AMESim; utilizing associated correlation state variables and parameters existing in the simulation process of the dynamic model and the multiport valve hydraulic system model as pass parameters between the two models, utilizing a Controls module of the ADAMS software and an interface module of the AMESim software to establish a software interface, carrying out real-time data transfer, and carrying out combined simulation on the dynamic model and the multiport valve hydraulic system model of the excavator; and checking a result in the hydraulic system simulation software. The method provided by the invention is conductive to improving the accuracy of the simulation result of the virtual prototype of the hydraulic excavator, and can be used for lowering the experiment cost, improving the experiment efficiency and shortening the design time.

Description

technical field [0001] The invention relates to the technical field of virtual prototypes of hydraulic excavators, in particular to a method for establishing virtual prototypes of hydraulic excavators. Background technique [0002] The multi-way reversing valve is the core component of the hydraulic system of the excavator, which largely determines the performance of the hydraulic excavator. At present, some main engine manufacturers in China have begun to independently develop key hydraulic parts of construction machinery including multi-way reversing valves due to their own development needs, but there is still a lack of necessary theory and sufficient technical support in design research. [0003] The traditional product development and design model based on physical prototypes faces many problems such as high design costs and long design cycles. In the fierce market competition, simply using this model has become a thing of the past. [0004] Compared with the tradition...
