连杆机构创意设计系统开发

A Development of Linkage Mechanism Creative Design System

为达到连杆机构快速建模,满足连杆机构创意设计的需要,给出了系统的总体设计和主要功能。分析了连杆机构的特点,归纳出8类基本构件,提出了统一的构件模型格式。同时,给出了由构件模型、运动副约束信息和构件初始位置信息组成的机构模型和可视化建模环境。采用笛卡儿方法建立连杆机构的多刚体系统运动学方程,实现了机构确定运动条件的自检与系统运动学方程的求解,并由动画演示机构运动形态。通过实例验证了系统的正确性和实用性。

To achieve fast modeling of linkage mechanism and meet the needs of linkage mechanism creative design, the system architecture and major functions of the system are given. The characteristics of linkage mechanism are analyzed, 8 categories of basic components are classified, and a unified component model format is proposed. Meanwhile, mechanism model and visualized modeling environment are given, which are composed of component model, pair constraint information and component initial point information. By using Descartes method to establish multi-rigid-body system kinetic equation, the system realizes self-checking of kinetic conditions and solving of kinetic equation, and kinetic morphology of mechanism is demonstrated by simulation. The system＇s validity and practicability are verified.
