The evaluation of stress intensity factors(SIFs)is a core mission in linear elastic fracture mechanics.Conventional displacement correlation method(DCM)for estimating SIFs faces a challenge of locatio
Unconventional gas reservoir like shale reservoir can trigger a series of coupling interactions between shale deformation and gas transport during gas production process.Although continuum flow has be
为了扩展EPS(Electric Power Steering)电动助力转向系统产品的设计开发和匹配标定能力,对某款乘用车建立了集成EPS系统电机驱动控制模型的整车动力学模型,并进行了仿真分析研究.首先对EPS系统的结构进行简化,分析了方向盘、转向管柱、转向输入轴、蜗轮蜗杆减速器、齿轮齿条转向机、车轮、直流有刷电机、基本助力及补偿控制策略等的功能原理,并推导了数学表达.
