It is particularly noticeable in case of non-proportional loadings, which lead to a reduction of fatigue life (i.e. [1–3]).
The proposed method has been validated using the experimental data for various types of multiaxial fatigue loadings.

When ; (7) When ; , (8) Because ,,are the values obtained after the FFT algorithm sampling data plus window, and therefore sub-peak and the peak value can be calculated.
The final comparison among the proposed algorithm, the basic FFT algorithm and the adding Hanning window algorithm is shown below with data sheet and figure plot.
The experimental data are listed in Table 2, which ordinary common FFT algorithm, Hanning window interpolation FFT algorithm data for the f0 = 50hz (fundamental frequency) simulation results, the data from reference.
Proposed algorithm simulation data, but also for the f0 = 50hz simulation.
By the contrast of simulation data, the interpolation FFT algorithm and the proposed algorithm in this paper have a higher calculation accuracy than ordinary common FFT algorithm as the error in the calculation of frequency, amplitude and phase are considered.

Therefore, in order to solve the problem of data management, process integration and collaboration in the process of complex product design and to shorten the design development cycle and reduce product development costs, improve product development quality.
The design of modern complex product is a MCD problem, which including multidisciplinary analysis, multidisciplinary design and multidisciplinary optimization, usually involve design data coupling of multiple disciplinary.
Design process of complex product is a collaborative work pattern of multidisciplinary, each design subtask usually isn’t sequential or concurrent, and has multi directions and different capacity levels of data exchange.
The purpose of design and construction MIDM is to determine from requirements to conceptual design, overall design data in all stages of the process, knowledge acquisition, design and analysis tools and other information as well as the organic association between this information, the definition of an interdisciplinary, cross-phase global model.
Summary MCD-oriented Integration of Product Design Meta-model(MIDM) was built, the process integrated control MIDM implementation methods was proposed based on MIDM, by means of MIDM, conducive to the process of product design and resource sharing and interaction, can provide complete multidisciplinary collaborative design process required of all applications geometric information and non-geometric information, including process data, model data and resource data.

In addition to the real-time process-data sophisticated evaluations can be carried out on the data in order to enhance product-related optimization or predictive maintenance.
Virtual Rolling Mill Architecture The Achenbach "virtual mill" consists of three modules: 1) models of the thickness and flatness behavior in the mill; 2) data acquisition [2], which handles the virtual coils and 3) respective controllers, see Fig. 2.
Basis records Database of Virtual Coils Mill Controllers Mill Model Task Process Data Mill Model MODEL VIS Rolled Coils Data PDA M-Target for Simulink Measured data Fig. 2: The "virtual mill" architecture Virtual Coils and Visualization.
Each pass (i.e. a single process step of thickness reduction in rolling) generates a new process data which serves for output coil creation.
The data acquisition system together with visualization software tool allows witnessing all important process values in real time.
