From the designer’s point of view, the static precise finite element model of the single ball-raceway, the overall and the unit slice of the rolling linear guide (RLG) are established based on the limited data obtained. According to the contact characteristics of a single ball-raceway, Hertz theory and finite element method (FEM) are used to determine the maximum contact stress and deformation of RLG under a specific preload value. The specific modeling process of the overall and unit slice finite element model of the RLG is described in detail as well. The comparative analysis results indicate that the unit slice finite element model can take place of the overall finite element model at the static level. On the basis of previous research, the mapping laws between external load, preload value, curvature ratio, the carriage’s wall thickness, the guide’s width, and static mechanical properties of RLG are studied. The combined application of these precise finite element models can solve the problems of large calculation and low efficiency in statics of RLG. Meanwhile, it also provides a new way to achieve high-efficiency and high-rigidity design of RLG from the source.

The Finite Element Model

This study was aimed at investigating the dynamic behaviors of the linear driven feeding stage by means of the analytical and finite element modeling approaches. To assess the dynamic characteristics of the stages with different linear guide arrangements, the finite element model of the stages was created, in which the linear components with rolling interface were accurately modeled based on the Hertzian theory. On the other hand, the analytically mathematical model was derived to determine how the linear guide arrangement affects the dynamic characteristics of the stage. Results of the modal analysis show that the vibration behaviors of the positioning stage are dominated by the rigidity of the linear components and the platform. In addition, comparisons of the results from the two approaches further indicate that the platform rigidity is an important factor determining the accuracy of the prediction of the vibration frequencies by the analytically mathematical model. As a conclusion of the study, the analytically mathematical model can approximate well to the finite element model when the linear stage is designed with appropriate structure rigidity.

The three-dimensional solid model and finite element model of an inertial navigation platform, is established by using ANSYS software. A modal analysis has been carried out. The former 6 ordered nature frequency and modal shape have been obtained and kept away from the frequency of Laser Gyro. The finite element model of the system vibration is established and is analysed for harmonic response. The calculation data show that vibration amplitude is very small and has no influence for the Laser Gyro working. The theory modal data is the same as the modal test results, so it manifests the accuracy and effectiveness in the modeling and analysis.

Commercial Aircraft

Commercial aircraft have well-designed and optimized systems, the result of a huge experience in the field, due to the large fleet of aircraft in operation. For light, utility, or sports aircraft, with a multitude of shapes, tasks, and construction types, there are different solutions that seek to best meet the requirements of the designed aircraft. In this sense, for a sport plane, an increased maneuverability is desired, and the system that controls flaps and wing must be properly designed. A new flap mechanism command solution is proposed and justified in the paper, for use in sports and recreational aviation, in order to achieve angles of braking greater than 40°, take-off and landing in a shorter time and over a shorter distance, as well as the gliding of the aircraft in critical flight conditions or when fuel economy is needed. A finite element model is used to verify the optimized command system for the flap and wing and to check if the strength structure of the aircraft is properly designed. The main result consists of the new design command system for flaps and wings and in verifying, by calculation, the acceptability of the new mechanism proposed from the point of view of the strength of the materials.

Abstract A finite element model was developed to simulate the tire-rim interface. Elastomers were modeled by nonlinear incompressible elements, whereas plies were simulated by cord-rubber composite elements. Gap elements were used to simulate the opening between tire and rim at zero inflation pressure. This opening closed when the inflation pressure was increased gradually. The predicted distribution of contact pressure at the tire-rim interface agreed very well with the available experimental measurements. Several variations of the tire-rim interference fit were analyzed.
