"Bioinspired Intelligent Approaches to Various Mechatronic Systems"

 各种机电系统的生物启发智能方法

【Abstract  摘要】

Studies of biologically inspired intelligence have made significant progress in both understanding the biological intelligent systems and developing innovative bionic applications to various mechatronic and robotic applications. In this talk, I will start with a very brief introduction to biologically inspired computation and learning, and some bio-inspired computational techniques. After that, several practical applications in engineering systems will be presented, such as intelligent e-nose systems with applications to agricultural and biomedical systems, and intelligent real-time path planning, tracking and control of various autonomous robotic systems.

"Morphing Via Shape Memory Materials and Technology"

 通过形状记忆材料和技术变形

【Abstract  摘要】

The function of morphing enables structures, machines and devices to switch their shapes according to the requirements and working conditions. For instance, solar panels are only deployed from their packed shape after the satellites reach the orbit. Medical devices used in minimally invasive surgery maintain the closed shape during delivery. Morphing wings are used in unmanned aeroplanes to change the wing shape according to the flight mode. Buttons-on-demand in future fully autonomous cars needs switchable keyboard. Among others, bi-stable structure, compliant mechanism, and tensegrity system are some examples that have been proposed in the past.

Shape memory materials (SMMs) are featured by the interesting shape memory effect (SME), i.e., they are able to return their original shape, but only when a particular stimulus is applied. Typical stimuli include heat, chemical, and light, etc. Two most popular types of SMM are shape memory alloy and shape memory polymer.

In this talk, a brief introduction of various shape memory phenomena will be presented first. After that, we will show a range of morphing applications in aero/space missions, biomedical devices etc. utilizing shape memory alloy and shape memory polymer.

"Reliability Analysis and Optimization of Key Parts of Low Pressure Cantilever Casting Machine."

 低压悬臂铸造机关键部件可靠性分析及优化

【Abstract  摘要】

The reliability of low-pressure cantilever casting machine directly determines product performance of castings. The cantilever beam and gear assembly are the key components of the low-pressure cantilever casting machine. Its reliability can directly affect the working performance and service life of mechanical equipment and the product quality of low-pressure castings. In this report, Firstly, the design and model of the gear system are carried out to obtain the specific parameters and simulation model of the gear transmission system. Secondly, each gear pair is dynamically analyzed by LS-DYNA to acquire the rotation speed, meshing force, contact stress and the time history curves of bending stress of the gear pair, and then to achieve the maximum contact stress and the maximum bending stress of the gear meshing in the running process of each gear. Quasi-static method is used to acquire the dynamic stress curves of each gear pair. The distribution forms and statistical distributions of contact stress are obtained by rain-flow counting method. On the basis of the stress intensity interference model, analytical function of dynamic reliability of gears is established. The dynamic reliability of gears is calculated by using MATLAB. The reliability of contact fatigue and bending fatigue of each gear teeth is acquired. According to the calculation of the gears’ reliability, the reliability of gears is optimized with the purpose of the minimizing volume of gears. The reliability analysis of cantilever beam is based on hybrid stochastic finite element method. The reliability of the cantilever beam is achieved.

低压悬臂铸造机的可靠性直接决定了铸件产品的性能,其中悬臂梁与齿轮传动装置是低压悬臂铸造机的关键部件,其可靠性能直接影响设备工作性能、使用寿命以及低压铸件产品质量。报告首先对传动系统进行设计和建模,得到齿轮传动系统的具体参数与仿真模型;再利用LS-DYNA对各齿轮副进行动力学分析,得到齿轮副的转速、啮合力、齿面接触应力以及齿面弯曲应力曲线,从而得到各齿轮在运转过程中齿轮啮合的最大接触应力和最大弯曲应力;利用准静态法获得齿轮副的动态应力时间历程曲线,通过雨流计数法统计各应力的分布形式与分布特征;基于应力强度干涉模型建立齿轮的可靠性分析功能函数;利用MATLAB软件计算齿轮的动态可靠度;基于齿轮强度的可靠度计算,以齿轮传动体积最小为优化目标对齿轮进行优化设计。报告对悬臂梁开展了基于混合随机有限元法的可靠性分析,得到了悬臂梁的可靠度。
