Accurate real-time truck simulation via semirecursive formulation and Adams-Bashforth-Moulton algorithm

引用

Acta Mechanica Sinica 2019年第3期35卷 641-652页

作者： Yongjun Pan Yansong He aki Mikkola School of Automotive Engineering Chongqing UniversityChongqing 400044China Department of Mechanical Engineering Lappeenranta University of Technology53850 LappeenrantaFinland

In this paper, a tailored four-step Adams-Bashforth-Moulton (ABM) algorithm is applied to a semirecursive formulation to perform a real-time simulation of a semitrailer truck. In the ABM algorithm, each integration step involves two function evaluations, namely predictor and corrector. This is fundamentally different when compared to the classic fourth-order Runge-Kutta (RK) integrator approach that contains four function evaluations. A semitrailer truck under investigation is modeled in term of a semirecursive method and simulated by using the presented ABM algorithm. The results show that the four-step ABM method can reduce CPU time almost 50% for solving the truck dynamics with very similar accuracy, in comparison to the fourth-order RK method. The presented ABM algorithm could be used in the semirecursive formulation to carry out accurate real-time simulation of medium-large vehicle systems.

Karyotype differentiation and reproductive isolation among natural populations of Drosophila lacertosa

引用

Cell Research 2003年第6期13卷 491-497页

作者： HIDE aki WATABE,TADASHI AOTSUKA Biological Laboratory Sapporo College Hokkaido University of Education Sapporo 002-8502 Japan Department of Biology Tokyo Metropolitan University Hachioji-shi 192-0397 Japan

Drosophila lacertosa is widely distributed from northern India to Far East of Russia throughout China. We have studied geographical distributions of three kinds of chromosomal karyotypes, type D (2n=10, 4 pairs of V-shaped metacentric chromosomes and a pair of micro-chromosomes), type L (2n=10, 5V with a pair of large-sized hetero chromatic autosomes) and type M (2n=10, 5V with middle-sized ones). Type D was found exclusively in local populations of D. lacertosa distributed in Yun-Gui Plateau, southwestern China. Both type L and M have a wide range of distribution, and the former occurred in subtropical regions of China including Taiwan Island, whereas the latter in cool temperate regions of East Asia covering Far East of Russia, Korea and the Japan Islands. A strong pre mating isolation was detected between flies with type D and those with type L or M. These data demonstrate that genetic differentiation leading to cryptic speciation might have occurred in natural populations of Drosophila lacertosa.

SINGLE AND DOUBLE EDGE INTERFACE CRACK SOLUTIONS FOR ARBITRARY FORMS OF MATERIAL COMBINATION

引用

Acta Mechanica Solida Sinica 2012年第4期25卷 404-416页

作者： Xin Lan Nao-aki Noda Kengo Michinaka Department of Mechanical Engineering Kyushu Institute of Technology

In this paper interfacial edge crack problems are considered by the application of the finite element method. The stress intensity factors are accurately determined from the ratio of crack-tip-stress value between the target given unknown and reference problems. The reference problem is chosen to produce the singular stress fields proportional to those of the given unknown problem. Here the original proportional method is improved through utilizing very refined meshes and post-processing technique of linear extrapolation. The results for a double-edge interface crack in a bonded strip are newly obtained and compared with those of a single-edge interface crack for different forms of combination of material. It is found that the stress intensity factors should be compared in the three different zones of relative crack lengths. Different from the case of a cracked homogeneous strip, the results for the double edge interface cracks are found to possibly be bigger than those for a single edge interface crack under the same relative crack length.

A NOVEL METHOD FOR EXACT SOLUTIONS OF ELLIPTICAL CRACKS IN PIEZOELECTRICS

引用

Acta Mechanica Solida Sinica 2005年第4期18卷 326-333页

作者： Xu Jian Chen Mengcheng Noda Nao aki School of Civil Engineering and Architecture East China Jiaotong University Nanchang 330013 China Kyushi Institute of Technology Kitakyushu shi 804-8550 Japan

According to the constitutive relationship in linear piezoceramics, elliptical crack problems in the impermeable case are reconsidered with the hypersingular integral equation method. Unknown displacement and electric potential jumps in the integral equations are approximated with a product of the fundamental density function and polynomials, in which the fundamental density function reflects the singular behavior of electroelastic fields near the crack front and the polynomials can be reduced to a real constant under uniform loading. Ellipsoidal coordinates are cleverly introduced to solve the unknown displacement and electric potential jumps in the integral equations under uniform loading. With the help of these solutions and definitions of electroelastic field intensity factors, exact expressions for mode Ⅰ, mode Ⅱ and mode Ⅲ stress intensity factors as well as the mode Ⅳ electric displacement intensity factor are obtained. The present results under uniform normal loading are the same as the available exact solutions, but those under uniform shear loading have not been found in the literature as yet.

Hyperbranched Polysiloxysilanes

引用

复旦学报（自然科学版） 2005年第5期44卷 736-737页

作者： Masa-aki Kakimoto Department of Organic and Polymeric Materials Tokyo Institute of Technology S8-26 Meguro-ku Tokyo 152-8552 Japan

Hyperbranched polymers have been paid attention because of their unique structures. Especially, they have many terminals whose number is the same as that of repeating units as far as they are synthesized from AB2 type monomers. These characteristics of the hyperbranched polymers make them new functionalized polymers. Polysiloxanes have unique properties such as low Tg, high decomposition temperature, water repulsion, and good dielectric property. They are widely fabricated from liquid (oil) to solid (resin) by changing the extent of crosslinking. We have studied dendrimers and hyperbrached polymers possessing polysiloxane structure. These materials have the amphiphilic nature when they have amine functional group at the terminal position.
