Method for simulating mechanism motion virtual experiment based on mechanical principles of members

Abstract

The invention relates to a method for simulating a mechanism motion virtual experiment based on mechanical principles of members. The method comprises the following steps of: 1) establishing the logic models of basic members in a uniform modeling language mode, namely Modelica, establishing the three-dimensional geometric models of the members by using three-dimensional modeling software, and integrating the three-dimensional geometric models of the members with the logic models of the members to establish a complete experimental member model which is described in extensible makeup language (XML); 2) constructing the experiment scene Modelica model of the virtual experiment, reading corresponding member files according to the members which are required by the experiment, selecting the three-dimensional models of the members, and assembling interfaces which are required to be connected among the members; 3) after the assembly is finished, setting simulation parameters, and starting the compilation solving simulation of the scene model; and 4) processing the data of a solving result file, and driving the visualization of a mechanism three-dimensional model in the assembly simulation environment of the virtual experiment. Compared with the prior art, the method for simulating the mechanism motion virtual experiment based on the mechanical principles of the members has the advantages that: boring theoretical knowledge becomes vivid and easy to grasp and has high universality, and the like.

Description

technical field [0001] The invention relates to a simulation method for mechanical power experiment teaching, in particular to a mechanism movement virtual experiment simulation method based on component mechanical principles. Background technique [0002] Multi-domain general modeling and simulation Modelica (MO) is an object-oriented, equation-based declarative modeling language proposed to solve the problem of multi-domain unified modeling and simulation of complex physical systems. [0003] OpenSceneGraph is a high-performance 3D graphics development library. It is widely used in visual simulation, games, virtual reality, high-end technology research and development, modeling and other fields. [0004] Traditional experimental teaching needs to provide students with a hands-on hardware environment and software environment, which requires a lot of teaching resources. In recent years, due to the increase in the number of students, there has been a certain pressure on exp...

Problems solved by technology

[0005] Most of the current virtual experiments are oriented to specific subjects, and there is no general development platform for virtual experiments. The development of virtual experiments is basically a single-piece development, which limits the popularization of virtual experiments in experimental education.
