The paper presents a study conducted to make multi-criteria optimization of electromechanical modules with a goal of providing easier tools for decision-making involving complex decision parameters. The work is motivated upon understanding that the task of both designing electromechanical modules and...

Fiber-optic gyroscope has become a new generation of leading device of inertial measurement system. Fiber-optic gyroscope is small batch product with high precision and high cost. Its development process has the characteristics of heavy testing work, complex data analysis, poor stability so that its...

In the recent years, the additive (layer) manufacturing technology, which emerged about three decades back, to assist design conceptualization and visualization through rapid prototyping, has created application interests beyond rapid prototyping. This transition beyond prototyping, i.e. transition to...

Fluid-structure interaction problems occur in a wide variety of science and engineering fields. In solving such problems, two domains of different characteristics shall be modeled and analyzed through separate kinematic equations. The complexity in the computation of such kind of problems arise mainly...

The shaft is the core transmission part of the motorized spindle. Based on the mechanical performance requirements and assembly requirements with other parts, this paper did the structural analysis on the shaft, and developed a set of high efficient manufacturing processes, including processing steps,...

The paper presents the second part a study conducted on multi-criteria optimization of electromechanical modules. This part focuses on the use of RAZOR method, which is a multi-criteria optimization outranking method, based on the so-called Z-score in statistics. The conducted study is motivated by understanding...

With the development of computer technology, data acquisition is more and more easily which can replace the manual recording process and improve the accuracy and efficiency of the data. So one experiment data acquisition system for the internal combustion (IC) engine was designed including the hardware...

In order to investigate friction and wear characteristics of 30CrMnSi-LD10-CS friction pair, the friction and wear test rig was built to measure the friction torque and wear coefficient under low speed, and mathematical calculation was used to figure out the relationship between friction torque and wear...

An effective flocking algorithm for multi-agent systems is presented. A type potential function is introduced for avoiding agents' inner collisions, and makes them formulate an -lattice pattern. The potential function creates a virtual force is only effective when the distance between two agents is beyond...

For significant differences in plant morphology at different growth stage after tobacco transplanting, using single boom sprayer leads to poor disease and pest control. This paper designed a multifunctional sprayer, to conduct boom spray to seedling stage, and to conduct tunnel spray to maturity stage....

In order to design a rational and lighter booms system of the High-Branch pruning forestry machine and improve the stability, this paper mainly studies three aspects about the boom system of the High-Branch pruning forestry machine: parametric design, physical modeling and dynamic simulation. Firstly,...

In the recycling of end of life vehicle, the residue of shredder composed of metal particles and non-metal particles. If non-metal particles is sorted into raw material with high purity, the recycling value of end of life vehicle will be increased. Due to the litter differences in the volume of solid...
