ASYMMETRIC DISTRIBUTION OF PIPE ADAPTER FOR CARS

It is shown that the responsible parts of each vehicle are tubular connecting lines, which included into braking, fuel and exhaust systems cars. These pipelines have high requirements for reliability, vibration resistance, strength, corrosion resistance durability. used as expanders elements when transitioning from a smaller pipeline diameter to larger one. The paper presents studies operation distributing end pipe blank with rigid punch. In process distribution, acting tangential stresses lead decrease in thickness edge section workpiece. This entails reliability this area during its maintainability resistance. Also, ensure tightness connections, threads cut or these areas welded together specified workpieces. Therefore, an important design feature diffusers same wall throughout cross-section semi-finished product. To solve problem increasing product after asymmetric tool proposed. task was solved finite-element formulation using special complex 3D modeling Simulia Abaqus – student edition. represented deformable solid, while punch modeled completely discrete solid. construction method both models "revolution". According finite element modeling, dispensing conical has advantages point view zone bell. part increases by 22.5% 1.77 mm classic version 1.82 distribution tool. reduce thinning blank, it recommended use obtain symmetrical socket, necessary make two transitions 180° rotation
