What is reverse engineering?
Reverse engineering plays a special role in the construction of accordion joints. Due to the great variety of molds and methods of production of fittings among different manufacturers of these products, producing a connection in accordance with the original design and design is usually costly and time-consuming. Because you have to use new templates to build such connections.
Therefore, the possibility of constructing and designing alternative connections is provided by reverse engineering. It is interesting to know that the installation specifications in the connections made in this way are fully preserved.The most important of these specifications can be the length of the connection, the fitting on the two ends of the connection and … He pointed out. In addition, some functional capabilities such as pressure tolerance, temperature tolerance, spring coefficients, etc. They can also be built in this way.It is worth noting that old projects are used in various centers such as steel construction، power plants، petrochemical industries، etc. Today, and using these new methods, they can be optimized. Even in some cases, using EJMA standards, a new edit can be applied to the connectors and increase the efficiency and service life of the connections compared to the original design.
How to Reverse Engineer Connections
In the reverse engineering process, the dimensions and sizes of the old accordion design must first be determined. This specification includes depth, number of blades, step, number of layers, layer thickness and … They will be.
Then you need to consider these old design specifications along with the working conditions of the connection such as temperature, pressure, movement, etc. He gave the software a design. These software can calculate spring coefficient and lifetime of each connection using the mentioned data. In new designs, by keeping operating conditions constant such as temperature, pressure and movement, as well as possible changes in some parameters of the blues, we try to create a product similar or better than the previous connection (in terms of spring coefficient and longevity).
Below is an example of the necessary calculations that have been developed using design software and the latest edition of EJMA standards. These calculations are for a universal 60-size accordion connection. According to calculations in the new design, the life of the connection has increased by about three times.
