Компоновочные схемы для моделирования трансмиссионных зубчатых механизмов
(БНТУ, 2008)While modeling transmission, two main types of models are used: a kinematic scheme and a CAD assembly. Both types have their own advantages and disadvantages as well. The kinematic scheme is flat and it doesn't contain special data to calculate loads. The CAD assembly - quite the contrary — is too detailed and it is rather hard to create this kind of model. This paper presents ...2019-11-15 -
