Determination Method of a Proper Small-Load-Omitting Criterion Based on the Extreme Load
Authors: Xu Zhi Qiang
Published: May 2013

A crucial step to obtain a reliable fatigue life prediction is to determine a proper small load threshold below which the cycles at small loads or stresses with high frequency causing little fatigue damage are truncated from the original load time history. By taking both the peak over threshold theory and the endurance limit threshold into account, a proper small load threshold is proposed in this paper. The optimal threshold should be high enough to remove the high-frequency small cycles and low enough to minimize the loss of the fatigue damage which maybe be truncated by the empirical small-load omitting threshold. Based on this proper threshold, the fatigue life prediction will be more reliable.

Authors: Zhang Zheng Kai , Gu Li Chen , Zhu Yong Sheng
Published: May 2013

It is well known that an engineering surface is composed of a large number of wavelengths of roughness that are superimposed on each other. Because these multi-scale features are related to different aspects of the processes the surface has undergone and closely related to the friction and wear properties of a surface, the analysis and characterization of these features becomes an important aspect of manufacture. The challenge is how to use them for acquiring knowledge and for aid to analysis. In this paper, a method for surface topography analysis is proposed based on bidimensional empirical mode decomposition (BEMD), which can provide good adaptive separation of surface texture into multiple hierarchical components known as bidimensional intrinsic mode functions (BIMFs). Applications are conducted by using a simulated surfaces to demonstrate the feasibility and applicability of using the bidimensional empirical mode decomposition method in the analysis of engineering surfaces.

As for the typeIassembly line balancing problem in complex products, the mathematical model of optimization goal is established with its optimization goal of minimizing the number of workstations as well as minimizing the differences in assembly complex relationship, and with the introduction of the framework of cultural evolution, a multi-cultural particle swarm algorithm is presented. The algorithm used arranged code so that the particle can still be able to meet the job constraints after its been decoded; using crowded distance to sort operator and remove the extra particles, in order to ensure a uniform distribution of the Pareto front; in order to improve the efficiency of the convergence of the algorithm, we adjust the flight parameters of particle basing on the dynamic changes in crowding distance. Through the comparison of standard test problems with other algorithms, we indicate the effectiveness of the proposed algorithm.

Published: May 2013

In order to respond to rapidly changing manufacturing environment and market, supply chain must be flexible, adaptable and reconfigurable. The potentials of changes in organization structure caused by changes in businesses must be taken into consideration during structural modeling of the supply chain. These can be accomplished with a fractal-based architecture. A structure model with the properties of self-similarity, self-organization, self-optimization, goal-orientation, dynamics and vitality is proposed in this paper. Fractal-based nature of the supply chain can be analyzed and optimized with the model, which adapts quickly to the dynamical change of the market.

Planetary gear sets have advantages of little noise, high transmission ratio, compact arrangement, so it has been widely applied in automobile and aerospace applications over the years. Using Lagrange equation, a free vibration theoretical model of a single planetary gear set was built, which was solved with modal superposition method. Combined with theoretical results, two types of modeling methods of planetary gear structures with the simulation platform SimulationX were studied. The simulation model suitable for analyzing vibration characteristic of planetary gear sets and inherent vibration characteristic in different situation were studied with the optimal modeling method. Important influencing factors of planetary gear sets vibration characteristic were studied and reference for dynamic best designing planetary gear transmission sets were provided.
