Mold shelf of powder molding press(PMP) is the main load component. Control the deformation of mold shelf is a key problem. In this paper, based on the basic theory of finite element analysis(FEA), the constraints and load conditions of main support parts of mold shelf were simulated and analyzed . ANSYS software optimized the structure of mold shelf. Top width of the stress part increased to 15mm, its height from 80mm down to 50mm. The results showed that the maximum displacement of mold shelf reduced to 0.4740mm, the maximum stress reduced 843.44MPa to 742.38MPa. Load distribution of the mold is more uniform, deformation and displacement also improved. It provides a new method and theoretical basis for optimal design of powder molding shelf.

Air Cushion

At present, it is inconvenient for use due to huge volume of common inflatable rubber fender. This paper introduces a design of cylindrical rubber sealing cushion which can be applied to various occasions to protect ships, dock and pier facilities. The key of air cushion technique is that it can produce a large displacement to buffer deformation and to reduce the exchange of energy. It plays a role to increase the time of collision, and then reduces the force of collision. Meanwhile, it also has good ability to adapt the tilted contact and it can float on the water surface, etc. This paper makes a feasibility analysis and strength calculation by doing theoretical calculation, and then making a force-test simulation by using ANSYS software, and do some structure optimal design according to the results of finite element analysis.

In order to verify whether the inputting cantilever of bucket-wheel reclaimer will be cracked and plastic deformation, in this paper, with inputting cantilever of modeling and finite element analysis, 3D entity model of inputting cantilever is established by using CATIA software. With the transmitting data interface of ANSYS software, it imports the inputting cantilever model, which is established in the environment CATIA, into ANSYS software. Through the static analysis on the inputting cantilever by the finite element software ANSYS, we can get static deformation diagram and von stress distributing diagram. From the analysis results, we can find the weakest spot according to the displacement cloud chart, and find the stress most centralized spot according to the stress analysis cloud chart, then carry on the intensity examination to it, and make description and mark on the maximum deformation and the maximum stress spot, and put forward the improvement plan to improve the service life. This method is a efficient path for the design and intensity examination of inputting cantilever, and it provides theoretical basis for further optimization design.

The study obtains a methodology for the bionic design of the tower for wind turbines. To verify the rationality of the biological selection, the Analytic Hierarchy Procedure (AHP) is applied to calculate the similarity between the bamboo and the tower. Creatively, a bionic bamboo tower (BBT) is presented, which is equipped with four reinforcement ribs and five flanges. Further, finite element analysis is employed to comparatively investigate the performance of the BBT and the original tower (OT) in the static and dynamic. Through the investigation, it is suggested that the maximum deformation and maximum stress can be reduced by 5.93 and 13.75% of the BBT. Moreover, this approach results in 3% and 1.1% increase respectively in the First two natural frequencies and overall stability.
