“…The most efficient way is to choose a small amount of sheet metals through sensitivity analysis, and then modify their thicknesses to accomplish the expected optimization object. The sensitivity technology is to analyze the sensitivity of response parameters when design parameters x i change [5][6][7], it can be expressed as, expressed in on the partial derivative of response parameters u j to design parameters x i in mathematics.…”

The structural analysis of a cab can examine its performances, and then provide a direction for structural optimization. This paper takes a frame-type cab as the research subject, its finite element model and corresponding test scheme are established, and then its torsion stiffness and modal characteristics are analyzed through both simulation and test. Appropriate variables for optimization are screened according to sensitivity analysis. Finally structural optimization for the cab is conducted, so that its torsion stiffness is improved effectively, and simultaneously the structural lightweight design is accomplished on the premise of maintaining the lower modal frequencies on the original level.

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.
