摘要
目的针对各种事故和自然灾害发生后受困伤员颈椎及脊柱伤情特点.对伤员快速固定装置进行优化设计。方法通过功能分析.进行三维建模设计.采用基于ANSYS Workbench的有限元分析和优化设计.拉伸强度验证.并制作样机进行试验。结果设计的伤员快速固定装置能满足对伤员实施安全救护的需求.通过优化设计.在不降低强度的前提下.自身质量约减少了30%。结论基于有限元分析的方法可明显优化结构.对其它相关救护装备的研制也具有参考意义。
Objective A rapid fixation device is developed to solve the problems of emergency fixation and transportation of patients with spinal injury.Methods Through the analysis of the function,3D modeling design,finite element analysis and optimization design based on ANSYS Workbench,tensile strength verification experiment,we produced the prototype,and tested it,conducted a simulated rescue experiment.Results The fixation device designed can meet the demand of spinal injury patients for safe rescue after accidents,and the quality of the rapid fixation device was lighten by about 30%without reducing the intensity.Conclusion The method based on optimal design can obviously improve the structure design,and has reference significance for other related rescue equipment design.
