The addition of attachments alters the vehicle’s center of gravity (CG) and may significantly affect stability and injury risk. This study developed and validated a multi-body finite element (FE) model of an ATV equipped with front and rear rack attachments, a tandem-axle trailer, and a 50th-percentile rider dummy to evaluate static rollover stability under varying operational conditions, enabling the assessment of configurations such as ATV-trailer systems that are costly and difficult to test experimentally. The model incorporated CG measurements obtained from tilt-table and corner-weight testing. Static stability was quantified using the tilt table ratio (TTR) under forward pitch, rearward pitch, and lateral roll conditions. Head injury risk was assessed using the 15 ms head injury criterion (HIC 15 ) during simulated rollover events. The FE model predictions of TTR showed good agreement with experimental results (average percentage error generally \u003C 10 %). Attachment configuration significantly affected stability across all rollover modes, with rear and combined rack loads producing the largest reductions in TTR. Lower tire inflation pressure reduced forward pitch stability and interacted with attachment configuration in lateral and rearward rollovers. Forward pitch rollovers generally produced the highest HIC 15 values, reaching 1095 for the ATV equipped with both front and rear racks. The relative severity of rearward pitch and lateral rollovers varied with attachment configuration. Nevertheless, nearly all predicted HIC 15 values remained below the accepted injury threshold of 700.","全地形车（ATV）广泛用于农业作业，但翻车事故仍是农场工人严重受伤和死亡的主要原因。加装附件会改变车辆重心（CG），并可能显著影响稳定性和伤害风险。本研究开发并验证了一辆配备前后货架附件、双轴拖车和第五十百分位乘员假人的全地形车的多体有限元（FE）模型，以评估不同作业条件下的静态翻车稳定性，从而能够对全地形车-拖车系统等实验测试成本高且难度大的配置进行评估。该模型纳入了通过倾斜台和角重量测试获得的重心测量值。静态稳定性通过前倾、后倾和侧翻条件下的倾斜台比值（TTR）进行量化。在模拟翻车事件中，使用15 ms头部损伤标准（HIC₁₅）评估头部损伤风险。有限元模型对TTR的预测与实验结果吻合良好（平均百分比误差通常小于10%）。附件配置在所有翻车模式下均显著影响稳定性，其中后货架载荷及前后货架组合载荷导致TTR降幅最大。较低的轮胎充气压力降低了前倾稳定性，并在侧翻和后倾翻车中与附件配置产生交互作用。前倾翻车通常产生最高的HIC₁₅值，对于同时配备前后货架的全地形车达到1095。后倾和侧翻的相对严重程度随附件配置而变化。尽管如此，几乎所有预测的HIC₁₅值均低于公认的损伤阈值700。",null,"Computers and Electronics in Agriculture","2026-09-11T00:00:00Z","论文",10,false,74,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},12,22,18,14,8,1,"核心期刊论文，用有限元模型量化农用全地形车挂载对侧翻稳定性与头部损伤的影响，方法新颖、数据可靠，对农机安全设计有参考价值，但属细分领域研究，公共影响范围有限。",[25],{"name":10,"url":6},[27,28,29,30,31],"智慧农业","职业安全","农机安全","农业机械","仿真建模",0,"10.1016\u002Fj.compag.2026.112377",{"doi":33,"openalex_id":35,"authors":36,"venue":10,"cited_by_count":32,"oa_url":6,"card":43,"direction":47,"ingested_from":49},"W7212322062",[37,40],{"name":38,"orcid":39},"Payam Farhadi","https:\u002F\u002Forcid.org\u002F0000-0001-5538-0598",{"name":41,"orcid":42},"Farzaneh Khorsandi","https:\u002F\u002Forcid.org\u002F0000-0002-1833-4311",{"tldr":44,"method":45,"finding":46,"direction":47,"opportunity":48},"用有限元模型评估农用全地形车加装附件后的静态稳定性与驾驶员头部损伤风险。","建立多体有限元模型，结合倾台与角重测试获取重心，计算TTR和HIC15。","后架及组合载荷显著降低稳定性，前倾翻HIC15最高达1095，但多数低于700阈值。","农业人工智能与决策模型","可结合真实田间地形与动态工况，开发附件配置优化与翻车预警的决策模型。","openalex","2026-09-13T23:30:02.142166Z"]
