Finite Element Simulation of Radial Tire Building and Shaping Processes Using an Elasto-Viscoplastic Model

The comprehensive tire building and shaping processes are investigated through the finite element method(FEM)in this article.The mechanical properties of the uncured rubber from different tire components are investigated through cyclic loading-unloading experiments under different strain rates.Based on the experiments,an elastoviscoplastic constitutive model is adopted to describe themechanical behaviors of the uncured rubber.The distinct mechanical properties,including the stress level,hysteresis and residual strain,of the uncured rubber can all be well characterized.The whole tire building process(including component winding,rubber bladder inflation,component stitching and carcass band folding-back)and the shaping process are simulated using this constitutive model.The simulated green tire profile is in good agreement with the actual profile obtained through 3D scanning.The deformation and stress of the rubber components and the cord reinforcements during production can be obtained fromthe FE simulation,which is helpful for judging the rationality of the tire construction design.Finally,the influence of the parameter“drum width”is investigated,and the simulated result is found to be consistent with the experimental observations,which verifies the effectiveness of the simulation.The established simulation strategy provides some guiding significance for the improvement of tire design parameters and the elimination of tire production defects.

Unfolding Evolution Strategically in Integrated Studios of Building and Design to Innovative Grasp of Design Creativity

In emergence of design, it is undoubted to be informed from nature for how things get done. But in architecture, the students are not used to start up with biological investigation. Instead of analogues, it is permitted to pursue an evolvability systematics for built emerge. The systematics relies upon the key assumptions of Kirschner who sought the characteristics of biological evolution. For an integrated design thinking of an architectural mind, this is a methodological study, which strategically adapts living forms＇ evolvability capacity to built-forms＇ structural emergence. The study outlines the evolution strategy with experimental studios of building and design. The preceding systematic is taught in distinguished courses. It is purposed to build an easy-to-apply framework for how to generate novel structures and how the spatial structure units are organized to emerge with an imagined nature as novel tectonic model. Besides, building up structural thinking into the consilience of evolution strategy, the study is also distinguished for understanding the value system of architectural mind to diagnose the genuine character of inventive built form. Strategy constructs processes. Thinking strategy concludes by the evolvability directives of studio assignments and they are given as flow-charts and project models.

Analysis of Style of Rockery Building and Stone Stacking Technique in the Royal Garden of the Song Dynasty: A Case Study of Genyue Royal Garden

Rockery building and stone stacking is a technique commonly used in building of classical gardens.Its emergence allows the fairy thought of"one pond and three mountains"to be reflected in different classical gardens.In the Northern Song Dynasty,the style of rockery building and stone stacking in the royal garden was an artistic climax in the history of the garden,and the technique of rockery building and stone stacking in Genyue Royal Garden was considered as the beginning of specialization.Through sorting out the records of the royal gardens in the Song Dynasty,this paper summarized the content of studying the royal gardens of the Song Dynasty,and systematically sorted out the development history of the techniques and styles of the royal gardens of the Song Dynasty and applied them into construction of some gardens.

Voluntary green-rating systems exist in different forms worldwide to certify the sustainability of residential and commercial buildings and help national policies promote energy-efficient design practices.Despite the general assumption that sustainable buildings also provide high comfort and healthy conditions,existing studies on green-rated buildings led to controversial conclusions in this regard. This paper aims to report the results of a post-occupancy evaluation (POE) conducted on four Swiss green buildings certified with the Minergie label to analyse their ability in providing comfort to their occupants.The POE protocol included winter and summer environmental monitoring campaigns (long-term and instantaneous measurements) as well as extensive and point-in-time comfort surveys. From the study it was found that,although the observed environmental factors were most of the time complying with the norm prescriptions,the indoor conditions were never attaining the commonly used 80 % satisfaction threshold by the users.Temperature and air quality appeared,in particular,as the most critical factors,with satisfaction rates never greater than 50 % in three out of the four case studies. Design factors related to the personal control on the indoor environment as well as personal factors like gender,climate of origin and duration of residence in the country were also found to have an impact in the comfort rating. Professionals involved in the design and management of these buildings all agreed that feedback of this kind from building in use could help inform the design and operational process and move towards more effective green building certification systems and regulations.
