Automação do sistema simulador de condições ambientais para teste de blindagem em vidros de veículos

Abstract

Improve the quality of their products is the relentless pursuit of all businesses. In the armored glass industry is no different, considering that the quality and durability of products guarantee the lives of users. One way to ensure the quality of products in the armor market is performing laboratory tests. This work was developed in a company where the aging process is performed by a commercial simulator Vostch brand, widely used in motor racing companies, medicines and food. However, the increased production demand arose the need to develop an environmental simulator for testing himself with armored glass, which was named SSCAVB. The commercial environment simulator Vostch works as a kind of oven or refrigerator which is placed the parts to be aged on the railings and performs the test. The tests are performed with UV radiation, temperature and humidity controlled. As specified by the manufacturer every ten days in test equivalent to six months of normal use. The SSCAVB has the UV lamp system (ultra-violet) and IR (infra-red), pneumatic actuators that make pressure on the glazing and vibrators, seeking a closer to reality simulation. Also, the SSCAVB has two controls: heating and cooling. Thus, the simulation test system allows the glass in mutual heating and cooling condition (one each side), subjecting the product to the characteristics of a glass under normal conditions of use. The construction of SSCAVB was performed with 100% domestic products, always looking for a cost / benefit. The automation of the system was carried out with Siemens programmable relay commercially known as Siemens LOGO with the program written in Ladder, perfectly performing the functions assigned to it. It was observed that while performing the tests in a short period of time the results were very interesting, the parts tested in SSCAVB had the same characteristics of the simulator Vostch.
