Simultaneous topology and size optimization of structures by genetic algorithm using minimal length chromosome

A. Kaveh, M. Shahrouzi

Layout optimization of structures aims to find the optimal topology and member sizes in an integrated manner. For this purpose, the most successful attempts have addressed the…

Probability characteristic of perturbing moments in contactless suspension systems for mass unbalance measurement of sphere

Xiao‐Xia He, Zhong‐Yu Gao, Yong‐Liang Wang

It is well known that precision of mass unbalance measurement of sphere is determined by perturbing moments in contactless suspension systems. Therefore, estimating perturbing…
