In order to prevent the accident of people entrapped in the grain mass of warehouse and protect the life safety of workers, the discrete element engineering EDM(EDEM) method was proposed to simulate the distribution of human body pressure. Firstly, the soft sphere particle model and the basic particle contact model Hertz-Mindlin (no slip) were selected to construct the wheat, corn and rice grain particle models, and the multi-body pressure model of the human body was constructed by coupling multi-body dynamics and EDEM. Secondly, the accident area model was constructed and the simulation parameters were set considering the factors such as accident scene and calculation amount. Finally, the simulation of particle motion process and the analysis of human body surface pressure were completed, and the human body force distribution measuring device of people entrapped in the grain mass was developed. The results show that the buried time of different grains is slightly different, with wheat being less than corn and less than rice. The maximum pressure on the surface of the human body can reach 1.4×10⁶ Pa which fluctuates violently. The average maximum pressure of the weighted sum of the wheat warehouse is 9 864 Pa, that of corn warehouse is 8 255 Pa, and that of rice warehouse is 7 283 Pa. The pressure distribution data provides a reference for accident prevention and related safety training, and provides ideas for the development of protective devices.

为预防平房仓粮堆埋人事故的发生，保护作业人员生命安全，采用工程离散元法（EDEM）仿真模拟人体压力分布。首先，选取软球颗粒模型和基础颗粒接触模型Hertz-Mindlin（元滑动）构建小麦、玉米和稻谷籽粒模型，并耦合多体动力学与EDEM软件构建人体多部位受力模型；其次，综合事故发生场景和计算量等因素构建事故区域模型，设定模拟参数；最后，完成颗粒运动过程模拟和人体表面压力分析，并开发粮堆埋人事故的人体受力分布测量装置。结果表明：不同粮种作业人员被埋的时间略有差异，由小到大依次为小麦<玉米<稻谷；人体表面压力最大值可达1.4×10⁶ Pa，各部位表面最大压力波动剧烈；小麦仓加权求和最大压力平均值为9 864 Pa，玉米仓为8 255 Pa，稻谷仓为7 283 Pa。压力分布数据可为事故预防和安全培训提供参考，也为防护装置的研发提供思路。
