[0030] Method Embodiment

[0031] According to an embodiment of the present invention, a method for hybrid simulation test of a building wind tunnel is provided. In the method, the test sub-structure includes a wind tunnel device, a scaled-down mast model, and a hybrid model shaking table. Figure 1 It is a flowchart of the method for hybrid simulation test of a building wind tunnel according to an embodiment of the present invention. As Figure 1 shown, the method for hybrid simulation test of a building wind tunnel according to an embodiment of the present invention specifically includes:

[0032] In step S110, the flowing wind is generated by the wind tunnel device and applied to the scaled-down mast model, the interaction force at the bottom of the scaled-down mast model is measured, and the interaction force is sent to the terminal device, which specifically includes:

[0033] At the start of the test, the wind tunnel device in the test sub-structure is used to simulate wind loads. In the field, if it is necessary to simulate other complex construction stage conditions such as earthquakes, the wind tunnel device used for the test is replaced with other test devices, which does not affect the scope disclosed by the present invention;

[0034] The scaled-down mast model retains the overall structure of the building, presents the key parts of the complex structure in a physical model, and comprehensively and realistically simulates the characteristics of high-rise buildings;

[0035] Obtain the shear force measuring device at the bottom of the scaled-down mast model, and measure the shear force at the bottom of the scaled-down mast model as the interaction force through the shear force measuring device.

[0036] In step S120, based on the interaction force and the numerical sub-structure formed by the main part of the scaled-down mast model, the target command for control is calculated by the terminal device, the time delay compensation is performed on the target command to obtain the compensated digital signal, and the compensated digital signal is transmitted to the real-time hybrid environment, which specifically includes:

[0037] The digital sub-structure adopts high-precision analog equivalence. In the embodiment of the present invention, the key vibrating layer is the 69th floor, corresponding to the 44th node of the numerical sub-structure;

[0038] Calculate the target command d for control through the Matlab program or Simulink program in the terminal device c , and in the embodiment of the present invention, the terminal device is a personal computer;

[0039] The specific meaning of the target command is related to the quantity that the control system needs to control, including but not limited to displacement, velocity, acceleration, etc. In the hybrid simulation test scenario, due to the existence of links such as actuators, signal transmission, and calculation, the system may introduce time delay. This time delay will cause the dynamic response of the system to deteriorate and may even cause instability. Therefore, time delay compensation is required, and the compensation amount can be calculated by the Smith predictor or the feedforward compensation method to obtain the compensated digital signal.

[0040] In step S130, the compensated digital signal is converted into an analog signal in a real-time hybrid environment, and the analog signal is transmitted to the shaking table controller, which specifically includes:

[0041] In the embodiment of the present invention, the real-time hybrid environment uses dSPACE / NI. In the real-time hybrid environment, the compensation command d p The corresponding compensated digital signal is converted through D / A conversion to generate a corresponding analog signal.

[0042] In step S140, the analog signal is converted into a driving digital signal by the shaking table controller, and the driving digital signal is transmitted to the hybrid model shaking table and the displacement feedback is received to adjust the operation, so that the test sub-structure performs interactive motion, which specifically includes:

[0043] The analog signal is converted into a driving digital signal through the closed-loop control algorithm inside the shaking table controller. The internal A / D conversion in the closed-loop control algorithm generates a corresponding driving digital signal, and the driving digital signal is transmitted to the hybrid model shaking table;

[0044] The hybrid model shaking table receives the driving digital signal to start vibrating. After starting, the hybrid model shaking table generates displacement feedback, and the displacement feedback is transmitted to the shaking table controller, and the shaking of the hybrid model shaking table is adjusted through the shaking table controller;

[0045] In the embodiment of the present invention, the displacement feedback is compared with the target displacement to calculate the displacement error. According to the displacement error, PID control or fuzzy control method, etc. are used to generate a control signal to adjust the vibration of the hybrid model shaking table;

[0046] When the interactive motion starts, that is, the hybrid model shaking table and the scaled-down mast model move relative to each other.

[0047] In step S150, during the interactive motion, a response solution algorithm is used to calculate the motion state characteristics of the control, which specifically includes:

[0048] An external sensor is used to measure the total force of the scaled-down mast model during the interactive motion, which specifically includes:

[0049] The formula 1 is used to calculate the total force of the scaled-down mast model. Since the amplifier of the acceleration sensor uses a low-pass filter, the transfer function of the low-pass filter used by the amplifier in the external sensor needs to be represented by formula 2 in the calculation of the total force:

[0050] f = f left + f right - H(s)·a up - plate Formula 1;

[0051]

[0052] Among them, f represents the total acting force measured by the scaled mast model, and f left represents the bottom shear force of the left mast, and f right represents the bottom shear force of the right mast, H(s) represents the transfer function of the low-pass filter, and a up-plate represents the acceleration of the upper tabletop, s represents a complex number, a0, a1, and a2 represent the coefficients of the numerator polynomial of the transfer function, and b0, b1, and b2 represent the coefficients of the denominator polynomial of the transfer function.

[0053] Obtain the response solution algorithm that was previously derived based on the motion equation through the newmark-β algorithm. According to the relationship between the equivalent load matrix and the equivalent stiffness matrix in the response solution algorithm, solve for the displacement characteristics, and substitute the displacement characteristics into the acceleration expression in the response solution algorithm to solve for the acceleration characteristics. Specifically, it includes:

[0054] Use formula 3 to represent the motion equation of the numerical substructure:

[0055] Ma i+1 +Cv i+1 +Kd i+1 =Hf i+1 Formula 3;

[0056] Among them, M represents the mass matrix, C represents the damping matrix, K represents the stiffness matrix, and Hf i+1 represents the total acting force matrix, a i+1 represents the acceleration matrix at the (i + 1)th moment, v i+1 represents the velocity matrix at the (i + 1)th moment, d i+1 represents the displacement matrix at the (i + 1)th moment;

[0057] Use formula 4 to calculate the displacement characteristics, use formula 5 to represent the equivalent load matrix in the relationship, and use formula 6 to represent the equivalent stiffness matrix in the relationship:

[0058]

[0059] Among them, represents the equivalent stiffness matrix, represents the equivalent load matrix, γ represents the first adjustable parameter, β represents the second adjustable parameter, and Δt represents the time step;

[0060] Use formula 7 to calculate the acceleration characteristics:

[0061]

[0062] Take the calculated displacement characteristics at the (i + 1)th moment and the acceleration characteristics at the (i + 1)th moment as the motion state characteristics. The obtained motion state characteristics are the responses at the layer nodes of the key main part.

[0063] Formulas 3 to 7 describe the process of using the inference result, and the derivation process is briefly described as follows:

[0064] During the derivation process, the velocity and displacement are approximated by the Newmark-β hypothesis. By transposing and arranging, the acceleration expression as shown in Formula 7 is obtained. Substituting the acceleration and velocity expressions into the motion equation as shown in Formula 3 and arranging, the expression regarding the displacement characteristics is obtained, namely Formulas 4 to 6.

[0065] Except for the detailed technical means disclosed in the embodiments of the present invention, technical means not described in detail such as the calculation of target commands, signal conversion, closed-loop control algorithms, etc. all adopt the content disclosed in the field.

[0066] In combination with the following drawings, the above technical solutions of the embodiments of the present invention will be illustrated by examples.

[0067] Figure 2 is a schematic diagram of the simulated overall architecture of the embodiment of the present invention, as Figure 2 shown, which shows the complete architecture schematic of the building wind tunnel hybrid simulation test. The equipment used includes test substructures, personal computers, shaker controllers, etc. The response calculation is based on the data of the numerical substructure.

[0068] Figure 3 is a schematic diagram of the response calculation at the key main body of the embodiment of the present invention, as Figure 3 shown, which shows the complete process of calculating the motion state characteristics of the key layer after starting the interactive motion, mainly divided into two parts: total force calculation and response solution.

[0069] In summary, in view of the problems existing in the current situation, the building wind tunnel hybrid simulation test method of the present invention uses the entire scaled-down mast model as the test substructure to fully present the overall structure and fit the actual state; only selects the key main body part as the numerical substructure to participate in the calculation to reduce the calculation burden.
