In the 21st century, Manufacturers will increasingly face frequent and unpredictable market changes. These changes include the frequent introduction of new products, increased demand for new products and new process technologies. To produce variety of product and suit to new processes automated/semi automated machine tools and fixture are required. In this paper present a fixture design for aut...

In this paper one class of anthropomorphic modular reconfigurable grippers for robots are described , including a prototype. For the first time the stages of synthesis, analysis design and functional simulation are presented. We choice two versions: with three and four identical fingers with three phalanxes on finger. The kinematic synthesis is used to obtain a correct closing of the finger and...

The aim of this numerical work is to analyze the effect of the position of the swimmer's head on the hydrodynamic performances in swimming. In this initial study, the problem was modeled as 2D and in steady hydrodynamic state. The geometry is generated by the CAD software CATIA and the numerical simulation is carried out by the use of the CFD Fluent code. The standard k-epsilon turbulence model...

Determining the real behavior of the windshield wiper mechanisms is a priority in the design stage since the emergence of the computer graphic simulation. The paper attempts to analyze and simulate the windshield wiper systems by using a complex virtual prototyping platform, which integrates specific software solutions for realizing the 3D solid model (CATIA), modeling the MBS mechanical model ...

Object manipulation is a basic task in robotics and automation. Active manipulation by grasp is conventional approach in object manipulation. However, in many cases, grasp-less manipulation can be beneficial in terms of cost, minimalism and extension of workspace. On the other hand passive mechanisms are advantageous from the energy saving viewpoint. In this paper we combine these ideas to deve...

Along with agricultural economy development, the farm machinery product type Increases gradually, the ergonomics question is also getting more and more prominent. The widespread application of computer aided machinery design makes it possible that farm machinery design is intuitive, flexible and convenient. At present, because the developed computer aided ergonomics software has not suitable hu...

This paper presents a methodology to be employed in the whole process design phase including first and second processing. This methodology consists of a set of steps which are characterised by an independent model. This paper’s objective is to analyse the coherence between the different models and the coherence between the model and the objectives of each step. The final stage is to develop the...

The detailed China Fusion Engineering Test Reactor (CFETR) 22.5° computer aided design (CAD) model is very difficult to convert into Monte Carlo N Particle Transport Code (MCNP). Manually writing MCNP input data complicated, which not only time-consuming but also cannot guarantee accuracy. Therefore, in order improve the efficiency and accuracy of transformation, modeling with CAD using CATIA i...
