    Abstract: ANSYS UserMat and its corresponding special MACRO are developed for implementing the linear matching method (LMM) for the limit analysis by using ANSYS. By this, pre and post-processing for the limit analysis can be done in the sole ANSYS circumstance without a help of any additional programs. Once user creates the FE model and enters the parameter... Show More

    Abstract: This paper presents a theoretical analysis of the forces acting on a helical gear transmission with an elastic element. The research investigates the effects of elastic deformation on the load distribution within the gear system, focusing on the influence of the elastic component on axial, radial, and tangential forces. The study employs mathematic... Show More

    Abstract: The article presents the results of theoretical studies conducted to determine the change in the length of the free strand of a chain drive with a variable center distance. In the research, the engagement of the chain with the driving and driven sprockets was considered as a 3-vector type, 5-link lever mechanism. During operation, in addition to na... Show More
