“…In this research, first of all, the optimal section sizes of frame members of one semi-integral fuel cell bus body are analyzed under four different load cases by applying common mechanism optimization design method [3][4][5][6][7]. Furthermore, orthogonal design of experiment method [8][9][10] is adopted to analyze the effect factor of the results in the synthesis optimization analysis and ascertain the integral optimum scheme.…”

In recent years, for the sake of energy saving and environment protection, lightweight body structure becomes the trend of vehicle development. Based on this objective, it is significant to make a research on optimization for the body structure. When structure optimization for the single work condition is carried out, the common mechanism optimization design method can provide the optimum result for certain condition according to the corresponding restriction and objective functions, whereas, the same variable has different variation trends in different conditions. In order to satisfy the requirements of the actual condition with multi-load cases optimization, synthesis analysis should be carried out by introducing weights for corresponding variables. First of all, the optimization section sizes of frame members of one semi-integral fuel cell bus body are analyzed respectively under four different load cases by applying common mechanism optimization design method. Furthermore, orthogonal design of experiment method is adopted to analyze the effect factor of the four optimization results in the synthesis optimization analysis and ascertain the integral optimum scheme. By analyzing and checking the bus body gained from the optimum synthesis scheme, it is confirmed that the synthesis optimization method for structure by adopting both common mechanism optimization design method and orthogonal design of experiment method can be used to carry out the optimization analysis under multi-load cases for bus body frame and the lightweight of bus framework, on the premise of ensuring the bus body performance index such as strength, stiffness and mode.

In this paper, a new type of vibration structure (i.e. swing frame) of vertical dynamic balancing machine is designed, which is based on the analysis of traditional double-plane vertical dynamic balancing machine’s swing frame. The static unbalance and couple unbalance can be separated effectively by using the new dynamic balancing machine with the new swing frame. The modal and harmonic responses are analyzed by using the ANSYS7.0. By comparing the finite element modal analysis with the experimental modal analysis, the natural frequencies and vibration modes are found out, which can provide the dynamics direction for designing vertical dynamic balancing machine. The new dynamic balancing machine can measure static unbalance and couple unbalance directly, and the influence between them is faint. The practical result indicates that the new vertical dynamic balancing machine is suitable for inertial measurement of flying objects, and can overcome the shortcomings of traditional double-plane vertical dynamic balancing machines, in which the effect of plane-separation is inferior. The vertical dynamic balancing machine with the new vibration structure can be widely used in the future application.
