中文摘要:

      目的 通过研究牙科椅俯仰角度的变化与人体舒适度之间的关系，为改善牙科椅的设计提供有力的参考依据。方法 测试不同俯仰角度下人体主观舒适度，基于CATIA（交互式CAD/CAE/CAM系统）人机工程设计与分析模块，在导入的牙科椅模型中引入三维人体模型，建立虚拟人机关系，结合人机工程学理论，对不同俯仰角度下人体姿态的舒适度进行仿真分析，利用SPSS统计分析软件对所得的数据处理。结论 牙科椅俯仰角度从0°转到60°的过程中，人体舒适度分值呈先上升后下降的趋势。人体最舒适的牙科椅俯仰角度为30°，最不舒适的角度为0°，同时验证了CATIA人机工程设计与分析的可行性。

英文摘要:

      By studying the relationship between the change of the pitch angle of the dental chair and the human body comfort, it aims to provide reference for improving the design of the dental chair. The human subjective comfort under different pitch angle is tested. Simulation analysis of the body posture comfort in different pitch angle is done based on CATIA(Computer Aided Tri-Dimensional Interface Application) man-machine engineering design and analysis module, introducing 3D human body model in the dental chair model, establishing virtual human-machine relationship, and combined with ergonomics theory. The data are processed by statistical analysis software SPSS. In the process of the pitch angle of the dental chair from 0° to 60°, the comfort score of the human body first increases and then decreases. The most comfortable dental chair pitch angle is 30°, the most uncomfortable degree of pitch angle is 0°, and the research verify the feasibility of the design and analysis of CATIA ergonomics.
