There is the theology of the plywood formaldehyde-emission which is similar to the solid and the liquid. The mature theory of rheological is applied to study on the mechanism of the plywood formaldehyde-emission in this paper, and the loose models of the plywood formaldehyde emission are created. The formularies FM = F0e-0.1429t and P = P0/k(1-e-0.1429t) can be received and used to describe the influence...
All flexible materials such as textiles, papers, polymers or metals are handled on rollers during their processing. Maintaining web tension in the entire processing line under changing web speed is a key factor for achieving good final product quality. Two approaches are mostly used for tension control: load cells which provide direct web tension measurement or dancers which indirectly regulate web...
With information technology and computer technology becoming popular, they are more frequently used in various disciplines. Through research on system dynamics in systems science, this paper thinks that they can definitely be applied to the physical education curriculum reform. Focusing on the issue, this paper also establishes a data model, accomplishes data analysis and sorting by using the advanced...
Many current evolutionary algorithms suffer from a tendency to prematurely lose their capability to incorporate new genetic material, resulting in a stagnation in suboptimal points. To successfully apply these methods on increasingly complex problems, the ability to generate useful variations leading to continuous improvements is vital. Nevertheless, there is a major difficulty in finding computational...
The purpose of this research is to enhance the structure of the 204-pin small outline dual in-line memory module (SODIMM) against the drop impact. According to the JEDEC regulations, the enhancement of PCB clips should be attempted to increase the resistance against drop impact. From high speed camera observation, the SODIMM module is pushed away from the PCB clips during drop impact. Therefore, the...
This paper presents a novel passive adhesion principle which is used firstly for an inspired modular climbing caterpillar project. After a related survey on the natural creatures which can climb on the vertical surface with different materials, a systematical summarizing on four attachment methods adopted by climbing robots worldwide is given. Then a low-frequency vibrating passive attachment principle...
A novel design for a Dielectric Elastomer (DE) actuator is presented. The actuator is obtained by coupling a conically shaped DE film with a compliant mechanism. The compliant mechanism is designed to suitably modify the force generated by the elastomer film. The resulting actuator provides a nearly constant force along the entire actuator stroke when the DE film is activated and quickly returns to...
The multiscale method has become a promising tool that could make a significant contribution to the fields of nano-science and technology. The objective of the multiscale method makes it possible to treat ever larger systems.Current study proposes a new model that combines the atomistic and continuum approaches. The continuum model is built on the lattice view and its critical deformation extent is...
The intention of this article is to introduce and overview Pneumatic Artificial Muscles (PAMs) as whole and to discuss on its numerical modelling, namely using the Finite Element (FE) Method, to understand more on its behaviour in generating force for actuation. The construction of PAMS mainly consist of flexible, inflatable membranes, having orthotropic material behaviour. The main properties shaping...
