摘要
在分析义耳形态特征的基础上,研究了义耳成型中成型曲线规划和成型方法,提出了将Stewart并联机构与三轴数控机床相结合的义耳快速成型方案,并建立了义耳的成型曲线数学模型.对成型方案中并联机构进行结构化参数设计和位置反解分析,得到了义耳成型过程中并联机构的姿态变换规律.最后,利用虚拟样机技术对并联机构进行运动学仿真,验证了成型方案的可行性与正确性.
By analyzing the morphological characteristics of artificial ear, the curve planning and the machining method in auricular prosthesis forming were studied and a quick forming scheme of combining parallel mechanism and 3-axis numerical control machine tool was put forward. Then, the mathematical model of forming curve was established. Through designing the structural parameters of Stewart parallel mechanism and inverse position analysis, the law of posture transformation of the parallel mechanism in the forming process was obtained. Finally, the virtual prototype technology was used to simulate the kinematics of the parallel mechanism, which verifies the feasibility and correctness of the forming scheme.
