Optimal Design of Spur Gears With Increased Contact Ratio
Journal of Mechanical EngineeringThe study is devoted to optimal design of gears with profile contact ratio εα ≥ 2. Optimality criteria formulated as follows: the contact stresses in the pitch point must take a minimum value when all constraints are met, first, when the profile contact ...

Influence of frozen capillary waves on contact mechanics
, 2005 Free surfaces of liquids exhibit thermally excited (capillary) surface waves. We show that the surface roughness which results from capillary waves when a glassy material is cooled below the glass transition temperature can have a large influence on the ...

Effect of Contact Geometry on the Contact Stresses in a Flat with Round Edge Contact
Frattura ed Integrità Strutturale, 2019 The blade-disc dovetail interface in an aero-engine compressor is characterized by a non-uniform pressure distribution which can be obtained by an equivalent flat with round edge-on-plate configuration. The contact tractions for a mating pair are affected by many parameters which include, contact geometry, loading conditions, and material properties ...
