摘　　要：为缓解自行车鞍座对人体坐骨的压力影响,基于人机工程学和有限元分析技术设计了轻量、舒适及安全的新型自行车鞍座及支撑杆。通过人体测量软件IDMATCH建立了人体骨盆骨距及接触点样本,并对载体结构进行法向力模拟与分析,得到鞍座支撑载体结构模型;采用鞍座压力测试系统MEDILOGIC对鞍座结构模型进行受力分析,给出不同人体百分位尺寸的鞍座布局极限尺寸范围和设计方案;结合有限元分析技术对最终方案进行测试、改进和验证。结果表明:基于人机工程和有限元分析技术设计的特殊鞍座结构能有效提升骑行舒适性,为自行车鞍座的人机工程应用和结构改进提供参考。In order to relieve the pressure of saddle on human ischia,a lightweight,comfortable and safe new style saddle and support rod were designed based on ergonomics and finite element analyses technology.Anthropometric software IDMATCH was used to establish human pelvic bone distance and the exact contact point samples.The normal force simulation and analysis of the carrier structure was carried out to obtain the saddle support carrier structure model.Force simulation and analysis of the saddle structure model was performed using saddle pressure test system MEDILOGIC to obtain the saddle layout limit size range and design scheme under the premise of different human body percentile sizes.The final scheme was tested,optimized and verified combine with dynamic finite element analyses technology.The results showed that the special structural design based on ergonomics and finite element analyses technology could effectively improve riding comfort.This provided new ideas for the ergonomic application and structural optimization of bicycle saddle.
