基于分段线性有限差分法,建立饱和土层一维大变形非线性热固结模型TCS2。该模型将土层热传导与固结变形相耦合,可以考虑土体自重、大应变、非线性压缩性和渗透性关系、温度效应和固结变形影响下土性参数的非线性变化。采用Fortran编写计算程序,并对该模型进行验证。小变形情况下,TCS2数值解与基于小变形假设的热固结解析解一致;大变形非线性条件下,TCS2数值解与室内试验实测值基本吻合。结合算例分析,进一步探讨土体自重、应变大小和应力路径对饱和土层热固结的影响,忽略土体自重、固结变形,以及简化的压缩性和渗透性关系,对土层热固结分析会产生较大误差。

It has been proposed that fusion reactions between neutron-rich light nuclei,for example 24C,24O and 28Ne,may contribute to achieving the ignition temperature for explosive carbon burning process during superbusrsts[1,2].Studies of fusion reactions involving neutron-rich nuclei are beyond ordinary experimental techniques,since the intensity of radioactive beam become low for these measurements[3].The active target technique using TPC(Time Projection Chamber),with properties of multi-sampling,high efficiency and low background,is a suitable solution to the problem.

针对大马力拖拉机在道路运输与田间作业过程中由于工况复杂、作业环境恶劣导致油耗高、节能效果差的问题,该研究采用油电混合动力匹配液压机械无级变速器(Hydro-Mechanical Continuously Variable Transmission,HMCVT)的方式,设计了一种油电混合—机液复合拖拉机动力系统,探讨了该系统的驱动模式与传动方式的实现原理并得到液压机械无级变速器的调速曲线;建立了动力系统的数学模型。为实现动力系统最佳性能,制定了整车控制架构,在此基础上提出HMCVT经济性速比控制策略、基于规则的工作模式划分策略和基于自适应等效因子的燃油消耗最小功率分配策略。为验证所提控制策略的可行性,在SimulationX仿真软件中建立系统动力学仿真模型,并基于测功机搭建试验台架进行测试,分别对拖拉机在犁耕、收获和运输3个典型工况下进行仿真与试验。结果表明,所设计的控制策略能够兼顾混合动力源的最佳扭矩分配与电池电量平衡,且动力系统能保持较高的系统效率(0.4以上),犁耕、收获和运输3个工况下油耗仿真值(2.59、6.56和1.69L)与试验值(2.72、6.80和1.77L)的误差均不超过5%,模型可靠。与德国农业协会公布的相近功率动力换挡拖拉机和无级变速拖拉机油耗数据相对比,该研究所提的控制策略在3种工况下节油9%~20%。研究结果可为多工况作业条件下降低拖拉机能耗提供解决方案。
