基于SQLite的实时动力学仿真平台模型数据库开发

Development of a Real-time Dynamics Simulation Platform Model Database based on SQLite

本文介绍了SQLite数据库的体系机构和技术特点,结合虚拟现实环境实时动力学仿真平台对模型进行动力学仿真所需信息的要求,建立综合传动装置模型数据库。通过调用SQLite的API函数,实现实时动力学仿真平台与SQLite模型数据库的链接。使用准备查询的方式,实现平台对模型数据库信息的读取和调用,为虚拟环境下模型的自动装配和实时动力学仿真奠定基础。

This paper introduces the system structure and technical characteristics of SQLite database,and establishes the comprehensive transmission model database by combining with the requirement of the real-time dynamic simulation platform of virtual reality environment for the model dynamic simulation.The real time dynamic simulation platform is connected to the SQLite model database by calling the API function of SQLite.The platform can read and invoke the information of the model database by means of the prepared query,which lays a foundation for the automatic assembly and real-time dynamic simulation of the model in the virtual environment.
