Embodiment 1

[0057] Embodiment 1 Co-simulation of actuator stress field

[0058] The stress field analysis of the actuator adopts the co-simulation of AMESim and ADAMS, and is described through the crank slider mechanism. The crank-slider mechanism refers to a planar linkage mechanism that uses a crank and a slider to achieve mutual conversion between rotation and movement; the component that forms a moving pair with the frame in the crank-slider mechanism is a slider, and the crank and slider are connected through a rotating pair. The components are connecting rods. The mechanism model of the slider-crank mechanism is established in ADAMS, the force model is established in AMESim, and a sinusoidal force is applied to the crank of the slider-crank mechanism to realize the movement of the slider following the change of the force within a limited displacement and make the connecting rod flexible Investigate the stress and deformation value of the connecting rod.

[0066] Embodiment 2 Co-simulation of electromagnetic field and control circuit

[0067] The 28V low-voltage DC power generation system is an integrated system integrating control, circuit and generator body. The analysis of this type of generator requires not only the calculation of its transient magnetic field, but also the consideration of the control circuit. The 28V DC generator circuit model is established on the platform of ANSYS\TwinBuilder, and the 2D magnetic field model is established in Maxwell to conduct electromagnetic field simulation analysis on the generator. The model consists of four parts, and the interaction relationship between each part is as follows: Figure 8 shown.

[0068] The motor model is a permanent magnet synchronous generator, and the model is a 2D electromagnetic field finite element model of maxwell. The control circuit is built with Twin Builder, and the control mode is a typical DC-DC buck circuit; the control principle is: the output AC ...

Abstract

The invention discloses a method for realizing hybrid dimension joint simulation by utilizing dynamic parameter mixing, and the method comprises the following operations: 1) after selecting a boundary condition, constructing a simulation model and performing field steady state simulation; 2) performing order reduction processing and data reconstruction on the steady-state field simulation result to construct and form an agent model; 3) importing the proxy model into the simulation model, and performing applicability check according to the model requirements; 4) importing the proxy model meeting the requirements into a system simulation tool, adding the system simulation tool into a multidisciplinary joint simulation platform of a distributed architecture, and realizing mixed-dimension joint simulation based on a data interaction tool. The main difference between the method and the static parameter mixing is that the static parameter mixing is parameter identification and loose coupling of the steady-state field simulation model, and the dynamic parameter mixing is proxy model reconstruction and loose coupling of the steady-state field simulation model.

Description

technical field [0001] The invention belongs to the technical field of simulation, and relates to a method and a system for realizing mixed-dimensional joint simulation by using dynamic parameter mixing. Background technique [0002] Complex products and systems have interdisciplinary information, and the manufacturing and testing of physical products has a long cycle and high cost. It is necessary to use multidisciplinary joint simulation technology to analyze the structure and performance of complex products and systems in the early stage of development. The purpose is to Reduce cycle time and cost. With the continuous increase of product complexity and system coupling, single-disciplinary simulation cannot meet the needs of engineering applications, and multi-disciplinary joint simulation, especially the joint simulation between low-dimensional system simulation and high-dimensional field simulation, is becoming more and more urgent. . [0003] There are two ways of dim...
