Problems solved by technology

Traditional development often adopts physical verification methods, which have a long research cycle, high cost, and low efficiency. Only by designing products and optimizing the design of each part from the perspective of the system can we design products with excellent performance to meet the increasingly fierce market competition and increasingly demanding technical requirements. Therefore, building a mechatronics co-simulation platform has strategic significance for product development.

Embodiment Construction

[0008] Embodiments of the present invention are further described below in conjunction with accompanying drawings:

[0009] The electromechanical-hydraulic control co-simulation method provided by the present invention designs the mechanical part of the electromechanical product under UGNX, designs the electrical part under Matlab / Simulink, simulates the hydraulic system under AMESim, and transmits the control information to UGNX and AMESim respectively by Simulink, Then the three perform joint simulation to analyze the dynamic characteristics of electromechanical products.

[0010] Such as figure 1 As shown, the three-phase asynchronous AC motor in Simulink transmits the speed information and servo valve control information to AMESim, and transmits the speed information to UGNX, and AMESim transmits the displacement information of the hydraulic push rod to UGNX.

[0011] The specific steps of the design under UGNX are that UGNX adopts version 8.0,

[0012] 1) Start UGNX, in...

Abstract

The invention relates to an electromechanical hydraulic control united simulation method. A mechanical portion of an electromechanical product is designed under UGNX, an electrical portion is designed under Matlab / Simulink, a hydraulic system is simulated under AMESim, control information is respectively transmitted to the UGNX and the AMESim through the Simulink, then united simulation is conducted through the UGNX, the AMESim and the Simulink, and dynamic characteristics of the electromechanical product are analyzed. According to the electromechanical hydraulic control united simulation method, united simulation is used, and physical characteristics and dynamic characteristics of the mechanical portion and the hydraulic portion can be more comprehensively reflected into a control system, so that the simulation reliability of an electromechanical hydraulic system is higher.

Description

technical field [0001] The invention relates to a joint simulation method of electromechanical and hydraulic control. Background technique [0002] With the improvement of market demand and the rapid development of science and technology, the requirements for the design and development of electromechanical products are also getting higher and higher. Traditional development often adopts physical verification methods, which have long research cycles, high costs, and low efficiency. They can no longer meet the rapidity and diversity requirements of modern design, and cannot cope with complex and changeable market demands. Therefore, according to the requirements of system dynamic performance indicators Only by designing products and optimizing the design of each part from the perspective of the system can we design products with excellent performance to meet the increasingly fierce market competition and increasingly demanding technical requirements. Therefore, building a co-s...
