Purpose This paper aims to summarize design rules based on the process characteristics of selective laser melting (SLM) and structural optimization and apply the design rules in the lightweight design of an aluminum alloy antenna bracket. The design goal is to reduce 30 per cent of the weight while maintaining the stress levels in the original part. Design/methodology/approach To reduce weight as much as possible, the titanium alloy with higher specific strength was selected during the process of optimization. The material distribution of the bracket was improved by the topology optimization design. The redesign for SLM was used to obtain an optimization model, which was more suitable for SLM. The component performance was improved by shape optimization. The modal analysis data of the structural optimization model were compared with those of the stochastic lightweight model to verify the structural optimization model. The scanning data were compared with those of the original model to verify whether the model was suitable for SLM. Findings Structural optimization design for antenna bracket realized the mass decrease of 30.43 per cent and the fundamental frequency increase of 50.18 per cent. The modal analysis data of the stochastic lightweight model and the structural optimization model indicated that the optimization performance of structural optimization method was better than that of the stochastic lightweight method. The comparison results between the scanning data of the forming part and the original data confirmed that the structural optimization design for SLM lightweight component could achieve the desired forming accuracy. Originality/value This paper summarizes geometric constraints in SLM and derives design rules of structural optimization based on the process characteristics of SLM. SLM design rules make structural optimization design more reasonable. The combination of structural optimization design and SLM can improve the performance of lightweight antenna bracket significantly.

We make modal analysis of single-screw strength general reinforcement worktable system and get the natural frequency and the vibration mode.Then in order to improve the system's natural frequency, the scheme of dual-screw worktable system is put forward. Also natural frequency and vibration mode is got. Finally, it is proved that the performance of dual-screw worktable system is significantly better than the single-screw one. This provides a reliable reference for further study on dynamic analysis of worktable system.

The energy storage technology is playing an important role in improving power grid stability. Aiming to the randomness and intermittent characteristics of wind power generation, the paper proposed a scheme of mechanical elastic storage energy and power generation system based on flat spiral spring. The flat spiral spring, which is the core component in the system, is selected as the research object, and the mechanical model and the finite element model is created. The geometric parameters of spring are determined. The maximum deformation and the stress distribution of spring are obtained. Moreover, the modal analysis of spring is carried out and the natural frequencies and modes of vibration of first 20 orders are obtained. The relationship between the natural frequency and deformation is also analyzed. All the results in this paper provide a strong basis for the optimization design of spring and the calculation of energy density.

Line inspection robot detects defects in high-voltage power lines, and it exists the instability of the movement in the process of surmounting obstacles due to its own gravity and vibration. So the robot is easily falling from the lines. The vibration sources of the line inspection robot with double manipulators of antisymmetric structure are mainly from the rotation of the walking motors of holding mechanism, the reversal motors of mechanical arm and driving motors of guide platform. This paper established the three-dimensional models of the line inspection robot's guide platform and conducted the statics and modal analysis. The results concluded the inherent frequencies and vibration modals of the guide platform, and then provided a theoretical guidance for the optimization design of the guide platform.
