Omer is a company with a strong production competence, and the engineering activities are carried out with the aim to propose solutions that minimize the production costs of the final product, and according with the requirements of the customer and the product specifications. Right from the preliminary phase of every project, the engineering department aims to develop technical solutions that achieve the best compromise between costs and benefits.
Every technical solution proposed can be supported by prototypes manufacturingof the individual components, and functional mock-ups to verify them with the body shell and the equipment installed on it. The engineering department is composed by specialized technicians and engineers, who are able to develop the entire project in the following phases:
• Management of the technical design documentation
• Production of 2D and 3D documentation for design development/modification
• FEM analysis
• Industrialization of the product
• Management of CAD/CAM processes
• Tool Design and Manufacturing
• Test Typing
• On site engineering support
At Omer, 3D modelling represents the key factor of the entire design-production system. 3D modelling is used during the development phase of the project, to verify the structures of particular items and how they interface with other systems or subsystems in the vehicle, to extract the information necessary for FEM verifications, and to significantly reduce the prototyping and management times of the packaging. 3D modelling is also used as a tool for generating all the necessary information for manufacturing the parts. The main software tools used for three dimensional modelling, and the other activities mentioned above, are Solid Edge and CATIA V5.
At Omer the design process is supported, validated and verified by structural FEM analyses and by experimental trials, often carried out at qualified European laboratories. The results of the FEM Analyses are then verified by laboratory trials on real prototypes, whichgive an important contribute to finalize the design solution and to obtain the best product possible, completely in line with the requirements of the customer. The tests are designed to evaluate one or more aspects at the same time, and are conducted for the purpose of simulating the real working conditions that the part will be subjected to.
In the railway sector, the scenario of the stress acting on the items produced by Omer generally involves:
• Static loads
• Fatigue loads
The following tests are therefore conducted, in line with the relevant regulations:
• Static load tests
• Shock and vibration tests
• Fatigue load tests
After a positive result in the tests described above, the part can finally be passed on to the next production cycle.
