Prediction models and multi-objective optimization of the single deposited tracks in laser direct metal deposition of 316L stainless steel

Autor: Doan Tat Khoa, Le Van Thao, Duong Van Nguy

Publikováno v: Manufacturing Review, Vol 11, p 14 (2024)

Laser direct metal deposition (LDMD) is a metal additive manufacturing process, which uses a laser source to melt metal powder and deposit the molten metal into the part layer-by-layer through a nozzle. With suitable process parameters and setting co

Design and performance analysis of a mechanically coupled spring compliant to out-of-plane oscillation

Autor: Duong Van Nguyen, Chien Quoc Nguyen, Hieu Van Dang, Hoang Manh Chu

Publikováno v: Archive of Mechanical Engineering, Vol vol. 69, Iss No 4, Pp 629-643 (2022)

In this paper, a spring system symmetrically arranged around a circular plate compliant to out-of-plane oscillation is proposed. The spring system consists of single serpentine springs mutually coupled in a plane. Three theoretical mechanical models
