高柔悬臂结构损伤识别的约束柔度法

为了识别高柔悬臂结构的损伤位置和损伤程度,提出损伤识别约束柔度法。推导出等效抗弯刚度分别与柔度矩阵各元素和与任一阶模态参数的关系等式,基于任一阶模态参数,将高柔悬臂结构简化为弯曲型集中质量模型,分析基于弯曲型集中质量模型的损伤识别柔度法的病态性,引入约束条件,建立低病态性的方程组,通过解方程组识别损伤。数值算例表明,所提方法识别效果较好,明显改善了损伤识别柔度法的病态性。     

Implementation and efficiency of two geometric stiffening approaches

When the modeling of flexible bodies is required in multibody systems, the floating frame of reference formulations are probably the most efficient methods available. In the case of beams undergoing high speed rotations, the geometric stiffening effect can appear due to geometric nonlinearities, and it is often not captured by the aforementioned methods, since it is common to linearize the elastic forces assuming small deformations. The present work discusses the implementation of different existing methods developed to consider such geometric nonlinearities within a floating frame of reference formulation in natural coordinates, making emphasis on the relation between efficiency and accuracy of the resulting algorithms, seeking to provide practical criteria of use.

A Perspective on Smart Process Manufacturing Research Challenges for Process Systems Engineers

The challenges posed by smart manufacturing for the process industries and for process systems engineering (PSE) researchers are discussed in this article. Much progress has been made in achieving plant- and site-wide optimization, but benchmarking would give greater confidence. Technical challenges confronting process systems engineers in developing enabling tools and techniques are discussed regarding flexibility and uncertainty, responsiveness and agility, robustness and security, the prediction of mixture properties and function, and new modeling and mathematics paradigms. Exploiting intelligence from big data to drive agility will require tackling new challenges, such as how to ensure the consistency and confidentiality of data through long and complex supply chains. Modeling challenges also exist, and involve ensuring that all key aspects are properly modeled, particularly where health, safety, and environmental concerns require accurate predictions of small but critical amounts at specific locations. Environmental concerns will require us to keep a closer track on all molecular species so that they are optimally used to create sustainable solutions. Disruptive business models may result, particularly from new personalized products, but that is difficult to predict.     

弹射架的ADAMS和ANSYS联合仿真

为了研究武器弹射架在发射筒伸出阶段以及导弹发射阶段的动力学响应状况,使用ANSYS对弹射架的关键构件进行了网格划分,并导入ADAMS,建立了刚柔耦合动力学模型。通过改变发射筒位置,研究了弹射架工作时关键构件的受力状态,计算了影响因子,从而确定了构件对发射筒位置偏移的容忍程度,为发射架的进一步设计以及实际加工提供了依据。
