Propeller is one of the critical parts in garbage powder mixer and affect significantly to the performance. In order to obtain a more reasonable structure, force analysis and stress analysis is carrier out for the propeller based on the actual working condition. Optimal design for the propeller is implemented by the results of stress analysis. To verify the rationality and feasibility of this mechanism, the finite element analysis for the propeller is performed by using the ANASYS software. The simulation results show that the maximum stress of the propeller is on the joint of blade and rod. The optimized propeller is satisfied with the strength requirements.

The Cost

As a result of enhanced performance and mission requirements for Navy ships, ship design has dramatically increased the use of higher strength, lightweight steels and various local reinforcements, e.g., deck inserts, ring stiffeners, etc., in foundation designs to satisfy the design requirements for supporting machinery, consoles, and weapon systems among others. In additional to operational loading requirements, most of these foundations must also be designed to satisfy shock, vibration and other combat system requirements. While the same piece of equipment may be used in other ship contracts, the foundations are uniquely designed and require a separate analysis and drawing package. Computer modeling and Finite Element Analysis (FEA) have helped reduce the labor required to analyze foundations, but the high number of “unique” foundations as well as changes which necessitate a new analysis still create a large workload for engineers. This is further compounded by increased costs in production due to greater numbers of unique parts and materials that must be marked, stored, and retrieved later for fabrication. This goal of this project was to determine the cost-savings potential of leveraging past foundations work in designing, analyzing, and drawing foundations in the future. By the project’s conclusion Ingalls will have created a database for rapid access to previously-generated foundation information, the framework of which will be publicly available for all shipyards to populate with their own foundation information.

This paper studies the force and deformation of the connecting channel in Ningbo rail transit construction, which firstly used the mechanical shield method. Steel-concrete composite structural segments are used in the T-joint of connecting channel. The cutting part of the segments are replaced by the concrete and fiberglass instead of reinforced concrete. Basing on a variety of three-dimensional design software and ABAQUS finite element analysis software, a refined finite element analysis model of the special segments is established. By considering the influence of curved joint bolts, the force analysis of the special segments under the structural state before and after construction is performed. According to the analysis and comparison of the deformation of the segments with and without the bolts, it is concluded that the steel-concrete segments can withstand the pressure of the soil before and after the construction. Suggestions for the safety of the design and construction of the segments are put forward.

To analyze the stress state of seed cotton in the process of cotton ginning and to improve the quality of lint, a new model for cotton, the laminated cotton model, is presented based on the idea of a composite laminate. The model assumes the cotton mass is made up of a certain number of cotton fibers, each of which has a different arrangement angle. Based on this model, the ginning process is simulated using finite element analysis. The mechanical properties of a single cotton fiber that is either machine- or hand-picked are obtained. The working condition of the ginning process is described successfully. By analyzing the influence of different working conditions on the serration cotton ginning process, the simulation results show the model prediction is reasonably consistent with existing experiments. For example, to improve the productivity and quality of lint, it is important to guarantee the saw teeth are sharp and smooth, with none being crooked or inverted, and missing teeth on each saw blade should not exceed the specified value.

The application of micropump in microanalytical reagent is widely. In this paper a piezoelectric micropump model that looks like a sandwitch has been put forward. The main structures of the micropump include inlet and outlet pipe, silicon substrate pump body, piezoelectric transducer. In order to find the excellent driving performance, the modals and piezoelectric-stress coupling analysis of the piezoelectric transducer has been carried out with finite element analysis methods. The result proves that the optimal working condition of the micropump is the 1st mode. Finally the micropump model has been fabricated with silicon deep reactive ion etching and UV irreversible irradiation. Through experiment the flow rate and pressure of the micropump reach the maximum in first-order modal that is less than 1000 Hz, and this is accord with the modal analysis.

The need for the rehabilitation of bridges and structures is becoming more apparent as the number of deficient civil structure grows and the cost of replacement is becoming prohibitive. These leads to the search of alternative methods, such as rehabilitation, to put the deteriorated structures back to normal operation with the least possible cost. One such method is the use of composite plates adhesively bonded to concrete as reinforcement and to prevent the propagation of crack within the concrete structure. In this study the load transfer and the resulting stress distribution in the composite-concrete adhesion system is investigated using the finite element method. The effects of the different bond parameters are studied using the finite element. In addition, results of the finite element analysis are proved to be in agreement with the analytical solution of shear stress distribution in the adhesion layer that was developed in previous studies by the authors.
