Generalized Random Tunneling Algorithm for Continuous Design Variables
Satoshi Kitayama,Koetsu Yamazaki +1 more
TL;DR: This method is called a generalized random tunneling algorithm (GRTA) because this method can treat the behavior constraints as well as the side constraints without using penalty parameters for thebehavior constraints.
Journal ArticleDOI
Study on optimal impact damper using collision of vibrators
TL;DR: In this paper, an impact damper which consists of multiple vibrators installed on a main structure and dissipates the vibrational energy by collisions between the vibrators is proposed, which is one of the optimization methods employed to determine mass and spring constant of every vibrators to maximize damping effect.
Journal ArticleDOI
Sequential approximate optimization for discrete design variable problems using radial basis function network
TL;DR: A density function is developed that, with the simple estimate of the width, works well in the case of continuous design variables and the permutation number is introduced to find the unexplored region of the discrete design variables.
Journal ArticleDOI
Numerical optimization of variable blank holder force trajectory and blank shape for twist springback reduction using sequential approximate optimization
Satoshi Kitayama,Ryoto Ishizuki,Masaki Yokoyaka,Kiichiro Kawamoto,Shinji Natsume,Kazuaki Adachi,Takahiro Noguchi,Toshio Ohtani +7 more
TL;DR: In this article, the authors proposed an approach for twist springback reduction using variable blank holder force (VBHF) trajectory that the blank holder forces (BHF) varies through the stroke.
Journal ArticleDOI
Determination of back-pressure profile for forward extrusion using sequential approximate optimization
TL;DR: In this article, a method for determining optimal back-pressure profile in forging of aluminum alloy using a sequential approximate optimization (SAO) was proposed, where an unfilled area was taken as the first objective function, and a forming energy during the forging was considered as the second objective function.
