基于二阶段随机规划的制造/再制造集成物流网络优化设计

基于二阶段随机规划方法提出了一种制造／再制造集成物流网络优化设计模型，据此确定网络中各种设施的数量、位王及物流量分配，以使运营周期内的净收益最大。谊模型的特点是：考虑了制造／再制造混合系统中产品需求量和可回收废旧产品数量的不确定性；考虑了正向物流和逆向物流的设施集成与运输整合以及回收中心的处理技术配备问题。最后，通过一个算例验证了谊模型的有效性。     

基于多体理论的履带车辆半主动悬挂仿真研究

在多轮车辆悬挂系统线性振动模型基础上，证明了悬挂最优阻尼比的存在。提出了统计意义上的最优阻尼控制策略，此即为履带车辆悬挂半主动控制的理论基础。通过基于多体动力学理论的虚拟样机方法对某型履带车辆整车悬挂系统进行了仿真研究，结合“机械系统＋控制系统”联合仿真技术。对比了该车分别采用被动悬挂和半主动悬挂时的动力学特性，得出了该履带车辆采用半主动悬挂可显著降低车辆振动加速度，提高车辆乘坐舒适性的结论。

40Ar-39Ar thermochronology of two ductile shear zones from Yiwulüshan, West Liaoning Region: Age constraints on the Mesozoic tectonic events

Two ductile shear zones trending EW and NNE respectively not only controlled the tectonic framework of the northern North China, but also constrained the geodynamic background for gold mineralization in this region. Field observations and microstructural analyses reveal that the EW trending ductile shear zones are mainly contributed to dextral compressional deformation resulting from top-to-the-southeast oblique thrust shearing, whereas the NNE trending ones are genetically related to sinistral strike-slip and extensional faulting. One sample from the former yielded an ⁴⁰Ar–³⁹Ar plateau age of (219± 4) Ma (Bi) and two samples from the latter gave ⁴⁰Ar–³⁹Ar plateau ages of (116± 2) Ma (Bi) and (127±3) Ma (Bi). These ages provide constraints on the top-to-the-southeast oblique thrusting event occurring in Late Triassic and the sinistral extensional and strike-slip faulting event which occurred in Early Cretaceous.
