EN17460 standard bonding certification training: elastic and rigid adhesive bonding joint testing and simulation research

Various types of adhesives are skillfully used in different parts of diesel locomotives. For the front window glass, it uses elastic glue of polyurethane or modified silane to give it flexibility and toughness; while for the aluminum profile inserts, it uses rigid glue with epoxy or acrylic components to ensure a stable structure. The selection of these adhesives is not just a random decision, but is subject to strict strength verification. The production of tension-shear joints is in accordance with the GB/T 7124 standard, which is a strong proof of its strength.

However, the verification work does not stop there. This article further uses finite element simulation calculations to deeply explore the performance of polyurethane elastic and epoxy rigid adhesives in tension-shear bonding joints. Simulating the bonding strength under different base material combinations is like exploring an unknown journey, with every step full of challenges and surprises. The comparison between the simulation results and the actual test results shows that they are exactly the same. This consistency provides strong support for batch bonding structure verification work.

The selection and testing of adhesives, like carefully selected ingredients, requires a careful cooking process to maximize their value. Polyurethane Adhesive A, this adhesive specially designed for motorcycle front windows, side windows and screen door glass, together with epoxy adhesive B, provides a solid guarantee for the bonding of fiberglass interior interior inserts. The substrate materials involved include fiberglass, aluminum, and steel, each of which has its own unique properties and needs to be fully considered during the bonding process.

In the world of simulation calculations, we use Ansys Workbench software, just like a chef using exquisite cooking skills, to model and simulate adhesive body tensile samples. Elastic glue has a large deformation capacity and is easy to shape like plasticine, but this also brings challenges to simulation. Traditional linear elastic material models perform accurately on small deformation data, but for large deformation data, you need to find other more suitable material models. Mooney-Rivlin model, Ogden model, Neo Hookean model, Yeoh model, and linear elastic model are like different cooking methods, each one has its own unique flavor.

The comparison between experimental results and simulation results is like the feeling of satisfaction after tasting delicious food, giving people a deeper understanding of the selected adhesive. The core material models and simulation methods developed by Yifa Bonding and Composites Research Institute are like the exclusive secret recipes of top chefs, which can accurately obtain parameter data that is consistent with actual testing. For different elastic glues, we have developed different material models, which are like delicacies tailor-made for customers to meet the needs of various tastes.

The mechanical simulation of bonded joints, like the art of cooking, requires a professional team to complete. After years of industry accumulation, Yifa Bonding and Composite Materials Research Institute has developed a series of courses called "Design Calculation and Verification of Bonded Joints", which are like a cooking school, providing knowledge and skills in bonding design for various industries. At the same time, we also have a CNAS-accredited testing laboratory, which is like the kitchen of a star-rated restaurant and can issue authoritative third-party testing reports to protect the quality of customers' products.

As the exclusive strategic partner of Germany's Fraunhofer IFAM in China, we provide EN17460 and DIN2304 certification audits, project support and consulting, just like the organizer of the International Food Festival, introducing world-class bonding technology to China. We also carry out three levels of bonding training and examinations issued by Fraunhofer: EAE European Bonding Engineer, EAS European Bonding Technician, EAB European Bonding Operator, as well as Composite-D, Composite-M, Composite-R, Composite- S's training and examination are like holding a cooking master class to cultivate more bonding technology experts.

In addition, we also provide special training courses related to customized bonding and composite material applications, which are like privately customized chef services to meet the individual needs of customers. At present, EAE European bonding engineer training standards have been upgraded from DVS-EWF3309 and EWF517 to EWF662; EAS European bonding technician training has also been upgraded from DVS-EWF3301 and EWF516 to EWF662; EAB European bonding operator training standards have been upgraded from DVS 3305 and EWF515 Changed to EWF 515.
