The automotive industry corporations noticed the advantages of automated laser welding. Robot laser welding systems have immediately attracted their interests for bringing down the production costs and delivering higher-quality items. The objective of this research is to study how to enhance heat dissipation to endorse a better performance of the pressure wheel, and help achieve a longer life cycle. Transient thermal analysis of the pressure wheel was conducted using ANSYS workbench. The work studied the effects of different design models and materials on the thermal performance of pressure wheel assembly during the cooling period. Numerical simulations were performed on both solid and geometrically ventilated wheels for enhancing the heat dissipation performance of the wheel. Different materials were also be tested and compared. The analysis will support the design process by monitoring different parameters in terms of performance, heat loss and manufacturing cost. A comparison was made for two different designs each with three different materials and the best design was selected. The simulation results in a period of 50 seconds cooling time showed that the temperature dropped with the 1st design (full solid wheel) made of tungsten from an initial temperature Ti = 500 K to a final temperature of Tf = 434.5 K. Tungsten was found to have better heat dissipation compared to stainless steel and cast iron. For the 2nd design (geometrically ventilated wheel) made of tungsten, the temperature drops from Ti = 500 K to Tf = 422.1 K. Comparing the two designs, the geometrically ventilated wheel was proved to be cooled faster. The present work will help improve the performance of pressure wheel in the welding industry by providing computational results for successive design testing and data validation.

Heat dissipation is considered as a challenging task in the manufacturing field. The main objective of this study is to design a new pressure wheel assembly of a laser weld system to maximize heat dissipation in order to endorse a better performance of the wheel and help achieve a long lasting cycle of life. In this study transient thermal and structural analysis of the pressure wheel is conducted by using ANSYS workbench. The work will examine the effects of geometrical parameters on the thermal performance of pressure wheel assembly during a period of time. Different design models and numerical simulations are performed in investigating the effects of geometrical holes and ventilated discs on the disk on the thermal performance, which include the shape, size, and distribution of pillar posts. The analysis will support the design process in monitoring different models in terms of performance, heat loss and manufacturing cost. A comparison is made for three different designs and the best design is selected. The calculated results estimated in a period of time of 50 seconds show that the temperature drops with the 3rd design from T = 500 K to 453 K. Also under giving limitations the design with enhanced heat transfer has a better heat dissipation and the temperature decreases to T = 399 K. The present work will help improve the performance of pressure wheel in the welding industry by providing computational results for successive design testing and data validation.

The Cost

Of many techniques that are used to optimize production and costs, the studies conducted within a profile company lead to our choice for testing the 6Sigma method (the most used method in the automotive industry) in view of the economic efficiency applied in the wood Industry company. This method measures how many flaws exist in a process and determines in a systematic way how to improve it by technical overhauling and eliminating or minimizing the process for efficiency. This research article aims to study the state of research on the optimization of the production process through technical overhauling for panels reconstituted from solid wood and ways to make production more efficient by cutting costs through technical overhauling. From preliminary research, we estimate that all the items founded and others that will result from further research will result in a significant decrease in production costs that are reflected in the cost of the finished product and consequently in increasing the yield of the company by maximizing its profit. At the same time it may be the basis of future research studies in the field. The easier it is to maximize profits, the lower the operating costs are and the higher recovery rate of investments are, that will result a change in the operating mode: “working smarter not harder”.

Filling And Solidification

At present, pulley produced in China has been able to meet the demand of domestic and international markets. But there are many problem of the pulley industry in our country, such as too many production enterprises and the low level of export products. And as components of drive system are light weight and raw material price of pulley casting are rising, manufacturing requirements of the pulley are also more and more high. Aiming at the casting defects of pulley that enterprise current product, pulley casting blank model of common material HT250 be made by three-dimension software, numerical simulation of filling and solidification process for pulley sand casting by the casting simulation software Procast, the size and location of the various casting defects were forecasted and analyzed, reflecting the pulley filling and solidification process of the actual situation, due to the thicker pulley rim and less heat dissipation, position of shrinkage is close to the middle of rim [, a method of eliminating defects is proposed to realize sequential solidification, and thus to minimize porosity shrinkage and improve casting performance and reduce casting time and reduce production costs.

The manuscript presents advanced coupled analysis: Maxwell 3D, Transient Thermal and Fluent CFD, at the time of a rated current occurring on the main busbars in the low-voltage switchgear. The simulations were procured in order to aid the design process of such enclosures. The analysis presented the rated current flow in the switchgear busbars, which allowed determining their temperature values. The main assumption of the simulation was measurements of temperature rise during rated current conditions. Simulating such conditions is a valuable asset in order to design better solutions for energy distribution gear. The simulation model was a precise representation of the actual prototype of the switchgear. Simulations results were validated by experimental research. The heat dissipation in busbars and switchgear housing through air convection was presented. The temperature distribution for the insulators in the rail bridge made of fireproof material was considered: halogen-free polyester. The results obtained during the simulation allowed for a detailed analysis of switchgear design and proper conclusions in practical and theoretical aspects. That helped in introducing structural changes in the prepared prototype of the switchgear at the design and construction stages. Deep analysis of the simulation results allowed for the development concerning the final prototype of the switchgear, which could be subjected to the full type tests. Additionally, short-circuit current simulations were procured and presented.

The automotive industry is one of the largest consumer of flexible hoses for fluids such as fuel or cooling. In order to limit the post production costs, every aspect of a vehicle must be tested in advance, including the lifespan, durability or failure of hoses. Throughout this paper summary results are presented for 4 types of fuel line hoses tested under controlled displacement loads at various pressures in order to validate the Finite Element Method simulations.
