Diseño y presupuesto económico de un sistema para pruebas de hermeticidad en la línea de ensamblaje final de buses, de la Empresa Carrocerías Yaulema Jr.

Abstract

The present work aims to design and obtain the economic budget for the future implementation of a technological system to perform tightness tests in the car body company Yaulema Jr. In its eagerness to grow as a company, it has decided the technification of this process due to that this test is of vital importance to comply with current regulations for the car bodies, which establishes the following: Ensure the tightness of the transport unit. The methodology applied is the documentary bibliographic review through which all the available information is collected and all the physical and construction parameters that are immersed and that are the reason for leaks in a bus, such as: rain, speed, quality of welds, coupling of windows, doors, windshield, placement of lights etc, are investigated and analyzed. Subsequently and taking into account all the information and knowledge acquired, a CAD modeling of the structural design was carried out, taking into account the quality, strength of the materials, the ergonomics of the system and other design parameters. With the calculation methodology, using formulas, the entire analysis of load losses in pipes, selection of pipes, pump and sprinklers that the system must have to simulate the rain and the impact of the same with the body car, was performed. Finally, we can conclude that this system will be very useful since it will allow us to check if there are filtration problems, before advancing to the final process, so it is recommended that rain simulation tests should be performed on 100% finished car bodies and before being delivered to its customers, since any additional element placed in the car body can generate filtrations.
