比例电磁铁作为比例阀中最关键的电-机械转换器,其位移-力线性度的优劣直接影响智能液压系统的精度,但是目前现有的比例电磁铁普遍存在位移-力线性度差、比例转换精度低等问题。针对此类问题,以比例电磁铁位移-力线性度为优化目标,结合田口法开展优化设计研究。首先,建立比例电磁铁输出电磁力数学模型,明确位移-力特性与极靴结构参数的映射关系。其次,基于衔铁4个典型位置下(0、d/4、d/2、d,d为衔铁行程长度)不同极靴结构参数的输出电磁力数值解,采用田口法得到所研究比例电磁铁关键结构参数的最优组合。最后,加工比例电磁铁样机,对比优化前后位移-力线性度的方差。结果表明,优化后的比例电磁铁位移-力线性度相比于优化前提升15.56%,验证了仿真模型的正确性和研究方法的可行性。研究成果对智能液压系统用比例电磁铁电磁性能的提升具有重要的指导意义。

熊十力接续心学一脉,在批判宋明理学静坐工夫有拘紧倾向的基础上,围绕孟子“尽心则知性知天”主张展开尽心工夫。在心性关系上,熊十力继承心学一元论的观点,将心、性、天等宋明理学范畴同质化。在心物关系上,与王阳明心外无物主张不同,熊十力持心物不二的观点,认为心物二分是导致工夫内外相分的重要原因,并提出化解工夫内外相分的办法是做好博文之功,即维持工夫在自然与人事两端的平衡。严格来说,熊十力并未能像朱熹、王阳明等宋明儒者一样构建起自身严密的工夫体系,但他对宋明理学工夫论的反思和批判对发展儒家工夫论具有重要的启发意义。

Chinese Journal of Mechanical Engineering 2007年第4期20卷 94-100页

A kind of novel multi-layer piezoelectric actuator is proposed and integrated with controllable constrained damping treatment to perform hybrid vibration control. The governing equation of the system is derived based on the constitutive equations of elastic, viscoelastic and piezoelectric materials, which shows that the magnitude of control force exerted by multi-layer piezoelectric actuator is the quadratic function of the number of piezoelectric laminates used but in direct proportion to control voltage. This means that the multi-layer actuator can produce greater actuating force than that by piezoelectric laminate actuator with the same area under the identical control voltage. The optimal location placement of the multi-layer piezoelectric actuator is also discussed. As an example, the hybrid vibration control of a cantilever rectangular thin-plate is numerically simulated and carried out experimentally. The simulated and experimental results validate the power of multi-layer piezoelectric actuator and indicate that the present hybrid damping technique can effectively suppress the low frequency modal vibration of the experimental thin-plate structure.

解体破碎效应普遍存在于高位岩质滑坡运动过程中,能够使滑坡物质状态与运动状态发生转变,从而影响滑坡的能量分布和动力传递特征.为探讨高位岩质滑坡碎屑流解体破碎特征与能量耗散规律,揭示其动力传递机制,采用大型物理模型试验,重点研究滑源区块体强度、方量、厚度、节理发育程度和坡度等对岩体解体破碎的影响.结果表明:高位岩质滑坡碎屑流在动力传递过程中,前部速度损失较后部明显偏少,前缘具有明显的“二次加速”,大量细小颗粒堆积于远端.滑坡体后部向前部具有明显的速度与动力传递效应,且破碎程度越高,动力传递效应越显著.解体破碎过程伴随能量的转化、传递与损失,在破碎程度控制下,破碎耗能约占总势能的3.32%~21.03%.
