In this paper, a multi-objective robust design method based on satisfaction function was proposed by combining satisfaction function with Taguchi robust to solve the multi-objective optimization problem, which was easily interfered by noise factor. This method converted the signal-to-noise ratio of product quality characteristics into the expected smaller-the-better of Taguchi robust design, and realized the multi-objective robust design by weighted geometric mean, so as to solve the multi-objective optimization problem easily affected by noise factors. Under the premise of without changing rotate barrel of basic size by LS-DYNA FE model of rotary guardrail, the proposed method was carried out on the rotate barrel of multi-objective robust design, in order to solve the new rotary guardrail section parameter uncertain multi-objective optimization design. The results showed that the robust design of the new rotate barrel could resist the interference of the noise, the structure was more robust, and it conformed to the relevant laws and regulations by which was realized the purpose of lightweight of the new rotary guardrail. The research results had certain theoretical and engineering significance in improving the robustness of the new rotary guardrail.

Ozturk 16 and Liu et al 17 proposed an efficient method to solve the fatigue problem of structure. In their study, a complex model (which is called parent model) is divided into several simple models (which are called child model or submodel).…”

Crane frame is one of the core components of the crane. Important performance indexes for the design of a frame include stiffness, manufacturability, and durability. Simultaneously, lightweight of the frame is also critical for decreasing the consumption of manufacturing and transportation. Crane is a complicated multibody structure, and therefore, using the traditional method to analyze will consume large amounts of computing time, and the accuracy cannot be expected. In order to solve these problems, a novel and effective method, super-element global modal parameterization, is employed in this article. The advantages of using this approach are that the complex models can be reduced, while the important effects are still taken into account. The design procedure consists of three steps: first, the finite element model is used to analyze the original frame. Then, the stiffness and von Mises stress obtained from the analysis are treated as the design constraints in the next topology and thickness optimization. Finally, a validation of the optimum design for durability is performed, and the results show that all the performances satisfy the requirements. The frame structure has a 15.12% reduction in total mass, while the performance is improved compared to the original.
