The developing world economy and the increasing income level cause the number of vehicles on the highways to increase rapidly. The increasing number of vehicles makes the highways more unsafe and increases the probability of accidents. This study is concerned with the dynamic analysis of axial and oblique compression in thin-walled tubes. Tubes under the effect of axial and oblique compression were compared with different cross-section profiles in terms of performance. Collision energy absorbed, crushing force efficiency, peak force, and velocity graphs are discussed in these performance parameters. The collision of the plates is discussed considering the speed and mass parameters that have entered the tubes using different cross-sections. Also, we developed a MOORA model integrated finite element analysis to rank the different alternative structures for different simulation cases. The MOORA model’s ranking results presented the most suitable cross-section profiles that will provide the most appropriate damping result.

The current deterministic optimization design method ignores uncertainties in the material properties and potential machining error which could lead to unreliable or unstable designs. To improve the design efficiency and anti-jamming ability of a high-energy ultrasonic igniter, a Six Sigma multi-objective robustness optimization design method based on the response surface model and the design of the experiment has been proposed. In this paper, the initial structural dimensions of a high-energy ultrasonic igniter have been obtained by employing one-dimensional longitudinal vibration theory. The finite element simulation method of COMSOL Multiphysics software has been verified by the finite element simulation results of ANSYS Workbench software. The optimal igniter design has been achieved by using the proposed method, which is based on the finite element method, the Optimal Latin Hypercube Design method, Grey Relational Analysis, the response surface model, the non-dominated sorting genetic algorithm, and the mean value method. Considering the influence of manufacturing errors on the igniter’s performance, the Six Sigma method was used to optimize the robustness of the igniter. The Eigenfrequency analysis and the vibration velocity ratio calculation were conducted to verify the design’s effectiveness. The results reveal that the longitudinal resonant frequency of the deterministic optimization scheme and the robustness optimization scheme are closer to the design’s target frequency. The relative error is less than 0.1%. Compared with the deterministic optimization scheme, the vibration velocity ratio of the robustness optimization scheme is 2.8, which is about 15.7% higher than that of the deterministic optimization scheme, and the quality level of the design targets is raised to above Six Sigma. The proposed method can provide an efficient and accurate optimal design for developing a new special piezoelectric transducer.

“…It can also be seen in the literature that the functional performance, structural integrity, and reliability of fuel booster pumps are often affected by various uncertainties including material variability and model uncertainty [ 15 , 16 , 17 , 18 , 19 , 20 ]. Therefore, in engineering practice, component failures (e.g., fatigue failure) that exist in the fuel booster pump arise randomly in nature due to the following reasons: the material properties of these components generally show a certain variability due to stochastically distributed defects; geometrical tolerances of these components are inevitable due to the manufacturing process or design margins [ 21 ]; expert cognition in reliability varies between different experts due to their different backgrounds and experience [ 22 ]; and operational data (e.g., time between failures (TBFs) and TTRs) and types of maintenance costs (corrective and preventive maintenance) are uncertain due to different maintenance strategies [ 23 ].…”

The fuel booster pump is one of the most vulnerable physical assets in an operating engine due to the harsh environmental and operational conditions. However, because of its high structural complexity and extreme operational conditions, the reliability design of the fuel booster pump becomes especially difficult, particularly by means of experiments. Thus, to overcome such a problem, advanced simulation techniques have become adequate solutions for the reliability assessment and analysis of a fuel booster pump at the design stage. In this paper, by considering the effects of the uncertainties of multiple design parameters, fatigue life distributions of the four key components (which are the sealing bolt, spline shaft, graphite ring, and inducer, respectively) in a fuel booster pump were first predicted by PoF-based reliability simulations. Then, through further sensitivity analysis on each key component, the design parameters most sensitive to the component mean fatigue life were detected from a total of 25 candidate parameters. These parameters include the “nominal diameter” and “preload” for the sealing bolt, “major and minor diameters of the small spline” for the spline shaft, “inside diameter” for the graphite ring, and “fuel pressure on the blade front surface” for the inducer, respectively. These sensitivity results were found to be in good agreement with the results from the qualitative cause analysis on each key component.
