摘　　要：目的针对人口老龄化、“空巢家庭”和伤残病等人群长期卧床而产生的压疮问题，设计一种结合智能卫生护理器使用的双向侧翻身机构。方法在建立该机构的三维模型的基础上，分析和计算了双向侧翻身机构的翻身角度。同时利用Pro／Mechanica对模型在平躺、侧靠和左佑侧翻身状态的受力情况进行了有限元分析。结果所设计的侧翻身机构双向翻身角度之和为300，选择的加工材料满足机构受力要求。结论本分析结果可以为设计人员确定双向侧翻身机构的结构参数和尺寸提供理论依据。Objective To aim at the problem of bedsore which is always occurred on the crowd of the aging population, ＂empty-nest family＂ and the disabled patients etc, a two-way side turn over mechanism for intelligent sanitation nursing instrument is designed. Methods The turn over angle of the mechanism was analyzed and calculated after establishing the mechanism＇s three-dimensional model. The forces situation of the state of lying, side lean against and left/right side turn over were carried out through finite element analysis by using of Pro/Mechanica. Results The results showed that the sum of two-way side turn over mechanism＇s two-way side turn over angle was 30 degrees. The materials met the mechanism＇s force requirement. Conclusions The results can provide a theoretical basis for the designer to determine the structure parameters and sizes of mechanism.
