El casco estándar se modifica teniendo en cuenta el módulo Peltier y el disipador de calor. Se diseña con éxito en 3D-Solidworks para adaptarlo a las necesidades de confort humano y teniendo en cuenta las medidas de seguridad de las personas. El análisis de la tensión estática se lleva a cabo en el casco modificado utilizando la interfaz de Ansys. El análisis experimental se lleva a cabo para cuatro casos diferentes considerando el módulo Peltier, considerando el módulo Peltier con el disipador de calor, por la presencia del módulo Peltier con la velocidad, por la presencia del módulo Peltier y el disipador de calor con la velocidad. Los resultados mostraron que el casco con módulo Peltier y disipador de calor en presencia de la velocidad proporciona más confort humano, ya que presenta más refrigeración, seguridad y ergonomía humana.

Le casque standard est modifié en tenant compte du module Peltier et du dissipateur thermique. Il est conçu avec succès dans 3D-Solidworks pour répondre aux besoins de confort humain et prendre en compte les mesures de sécurité humaine. L'analyse des contraintes statiques est effectuée sur un casque modifié à l'aide de l'interface Ansys. L'analyse expérimentale est effectuée pour quatre cas différents en considérant le module Peltier, en considérant le module Peltier avec le dissipateur de chaleur, par la présence du module Peltier avec la vitesse, par la présence du module Peltier et du dissipateur de chaleur avec la vitesse. Les résultats ont montré que le casque avec module Peltier et dissipateur de chaleur en présence de la vitesse offre plus de confort humain car il présente plus de refroidissement, de sécurité et d'ergonomie humaine.

É concebido com sucesso em 3D-Solidworks para se adequar às necessidades de conforto humano e tendo em consideração as medidas de segurança humana. A análise de tensão estática é realizada num capacete modificado utilizando a interface Ansys. A análise experimental é realizada para quatro casos diferentes, considerando o módulo Peltier, considerando o módulo Peltier com dissipador de calor, pela presença do módulo Peltier com velocidade, pela presença do módulo Peltier e do dissipador de calor com velocidade. Os resultados mostraram que o capacete com módulo Peltier e dissipador de calor na presença de velocidade proporciona mais conforto humano, uma vez que exibe mais arrefecimento, segurança e ergonomia humana.

Der Standardhelm wird durch Berücksichtigung des Peltier-Moduls und des Kühlkörpers modifiziert. Er wurde erfolgreich in 3D-Solidworks entworfen, um den Bedürfnissen des menschlichen Komforts gerecht zu werden und die menschlichen Sicherheitsmessungen zu berücksichtigen. Die statische Spannungsanalyse wird an einem modifizierten Helm mit Hilfe der Ansys-Schnittstelle durchgeführt. Die experimentelle Analyse wird für vier verschiedene Fälle durchgeführt: für das Peltier-Modul, für das Peltier-Modul mit Kühlkörper, für das Peltier-Modul mit Geschwindigkeit und für das Peltier-Modul und den Kühlkörper mit Geschwindigkeit. Die Ergebnisse zeigen, dass der Helm mit Peltier-Modul und Kühlkörper bei Vorhandensein von Geschwindigkeit mehr menschlichen Komfort bietet, da er mehr Kühlung, Sicherheit und menschliche Ergonomie aufweist.

To make the students to learn the fundamental concepts of managerial economics,various processes of production, types of business organization. The objective is also to make them to learn processes in price determination in different markets, different costing concepts and basic knowledge of accountancy. Students will understand the basic concepts of managerial economics and business organizations. Students can determine price of products in different markets. Students can perform cost analysis.Students can prepare profit and loss account and balance sheet.

1. The finite element analysis of Truck Chassis Frame is carried out using 10 noded brick element. The static and Modal analysis is carried out. 2. The Static analysis has a significant effect on the overall stresses in the Chassis Frame. 3. By using Stainless steel and Duralumin materials Static and modal analysis was done to see stress and mode shapes of structure. 4. By comparing Results of Stainless Steel and Duralumin. Finally, we can say Duralumin is better than Structural Steel. MATERIAL DEFORMATION(mm) STRESS (Mpa) Factor of safety STRUCTURAL STEEL 1.71 58.491 4.2 DURALUMIN 4.76 58.1 7.7 5. Chassis designed now is capable of withstanding to the loads up to 18 tones with minimum weight by using Duralumin. 6 . From tabular column Duralumin is better than Structural Steel. 7. . From the above table it can be understandable that though the deformation is more for . duralumin it is more stronger due to its higher factor of safety. 8. As Duralumin is a light weight material the weight of the chassis decreases and therefore . the vehicle efficiency increases.

The purpose of this work is to evaluate the life cycle and torsional vibrational stress of a marine propeller shaft. In the existing propeller shaft, we have evaluated the theoretical values of diameter at four positions of the shaft namely, After shaft, Mid part, Forward part and Intermediate part undergoing iterations. The most appealing iteration is chosen based on the power and values given based on tank testing model results. Due to these reasons, we considered the outer shaft diameter to be 600mm.The shafting analysis was carried out taking various inputs of propeller power, diameter, diameter, mas, inertia, damping, and excitation. The analysis from the software gave various results related to vertical bearing loads, vertical displacements, vertical bending moment and vertical bending stress. In order to maintain good alignment values, the shafting, whirling, axial and torsional vibrational analysis is conducted in cold static condition for a closed flange propeller shaft.In order find various parameters, analysis was done in ANSYS. The results were tabulated. The results obtained from ANSYS included maximum and minimum principal stresses, Von-Misses stress, total deformati

The standard helmet is modified by considering the Peltier module and the heat sink. It is successfully designed in 3D-Solidworks to suit the needs of human comfort and taking human safety measurements into considerations. The static stress analysis is carried out on a modified helmet using Ansys interface. The experimental analysis is carried out for four different cases by considering Peltier module, by considering Peltier module with heat sink, by the presence of Peltier module with velocity, by the presence of Peltier module and heat sink with velocity. The results showed that the helmet with Peltier module and heat sink in the presence of velocity gives more human comfort as it exhibits more cooling, safety and human ergonomics.
