Under this background, the seismic isolation system has become a core component of the mechanical and electrical equipment anti-seismic, and its performance directly determines the safety and survival ability of the equipment in the earthquake. Therefore, accurate monitoring and scientific evaluation of the performance of the seismic isolation system has become a key link to improve the anti-seismic reliability of the mechanical and electrical equipment. The traditional seismic isolation performance evaluation method mainly relies on a single sensor or a single data source for measurement, but due to complex environmental factors and structural characteristics, a single data source often cannot comprehensively and accurately reflect the seismic isolation performance. Based on this, the multi-modal data fusion technology has become a hot spot in recent years, and the combination of various sensors such as acceleration sensors, strain gauges, temperature sensors, and displacement sensors can obtain seismic efficiency information from different angles, thereby realizing accurate monitoring and evaluation of the state of the seismic isolation device.

[0105] The equivalent viscous damping ratio corresponding to each monitoring point is taken as the isolation energy consumption coefficient corresponding to the monitoring point.
[0106] In the scheme, multi-dimensional dynamic modeling, energy loss quantification and accurate parameter extraction realize the whole-chain empowerment from simulation test to engineering optimization in intelligent analysis of isolation performance. Through the calculation of hysteresis curve and hysteresis loop area, the nonlinear mechanical behavior of the isolation system is converted into quantifiable energy consumption indicators, and the hysteresis loop area directly corresponds to the single-period seismic energy consumption (such as the ring area of 0.8kN·m of the sliding friction type isolation device, indicating that 800J of energy is dissipated per cycle), helping engineers to intuitively evaluate the isolation efficiency under different working conditions;

Especially in high-intensity earthquake areas, the accurate evaluation of the energy consumption capacity of the isolation system provides core technical support for the safety target of building structures.
[0111] Specifically, according to the basic seismic test data, the seismic stress feature points are obtained, specifically including:
[0112] According to the base isolation level information, obtain base isolation level transverse wave intensity information and longitudinal wave intensity information;
[0113] According to the base isolation level information, obtain base isolation level transverse wave intensity information and longitudinal wave intensity information;
[0114] According to the target isolation level information, obtain target isolation level transverse wave intensity information and longitudinal wave intensity information;
[0115] According to the target isolation level information, obtain target isolation level transverse wave intensity information and longitudinal wave intensity information;
[0116] According to the base seismic test data, obtain the transverse wave maximum displacement point and the longitudinal wave maximum displacement point of the isolation system;
[0117] According to the base seismic test data, obtain the transverse wave maximum displacement point and the longitudinal wave maximum displacement point of the isolation system;
[0118] According to the base seismic test data, obtain the transverse wave maximum displacement point and the longitudinal wave maximum displacement point of the isolation system;
[0119] According to the base seismic test data, obtain the transverse wave maximum displacement point and the longitudinal wave maximum displacement point of the isolation system;
[0120] According to the base seismic test data, obtain the transverse wave maximum displacement point and the longitudinal wave maximum displacement point of the isolation system;
[0121] According to the base seismic test data, obtain the transverse wave maximum displacement point and the longitudinal wave maximum displacement point of the isolation system;
[0122] In this scheme, through hierarchical simulation test, feature point positioning and stress trend analysis, the visualization of seismic response law and the accurate extraction of key parameters are realized in intelligent analysis of isolation performance. Through the differential test of transverse and longitudinal wave intensity of base and target isolation levels, the earthquake scene is simulated comprehensively. The base level test simulates the conventional earthquake working condition (such as fortification intensity 7 degrees), and the target level test covers extreme working conditions (such as 8 degrees rare earthquake), ensuring that the isolation system performance test covers more than 95% of the actual earthquake scene, avoiding the evaluation deviation caused by single test working condition. The horizontal shear and vertical impact of transverse and longitudinal waves simulate earthquakes respectively, and through independent test and comparison, the response difference of the isolation system to different seismic waves can be quantified, ensuring the authenticity of the earthquake simulation, and determining the data basis for the isolation performance analysis. Through the transverse / longitudinal wave maximum displacement point, the stress concentration area of the isolation system is directly locked, avoiding the inefficiency of global analysis.
[0123] Specifically, based on the equivalent force corresponding to the basic isolation level information and the target isolation level information, the strain characteristic force is obtained with the seismic stress characteristic point as the reference, specifically including:
[0124] The sum of the distances of the first feature point, the second feature point and the seismic stress characteristic point is taken as the stress offset value corresponding to the basic isolation level;
[0125] The sum of the distances of the third feature point, the fourth feature point and the seismic stress characteristic point is taken as the stress offset value corresponding to the target isolation level;
[0126] According to the basic isolation level information and the target isolation level information, the basic maximum force information and the target maximum force information are obtained based on the equivalent force;
[0127] The sum of the stress offset values corresponding to the target isolation level and the basic isolation level is taken as the stress offset characteristic value;
[0128] The product of the ratio of the stress offset value corresponding to the basic isolation level to the stress offset characteristic value and the basic maximum force is taken as the basic offset force;
[0129] The product of the ratio of the stress offset value corresponding to the target isolation level to the stress offset characteristic value and the target maximum force is taken as the target offset force;
[0130] The mean value of the basic offset force and the target offset force is taken as the strain characteristic force.
[0131] In this scheme, by calculating the stress offset value, the response difference of the isolation system under different levels of earthquakes is converted into a measurable index. By taking the seismic stress characteristic point as the reference, the stress offset values of the basic and target isolation levels are compared, which can intuitively reflect the performance fluctuation of the system under normal and extreme working conditions. Based on the basic and target maximum forces, the offset force is calculated by combining the stress offset ratio, which realizes the dynamic fusion of the stress under different seismic levels. This method not only considers the stability performance under normal working conditions, but also takes into account the bearing limit under extreme working conditions, so that the calculated strain characteristic force is more in line with the actual complex earthquake scene. It can accurately simulate the limit stress state of the isolation system under rare earthquakes (such as high intensity areas), and the strain characteristic force as the mean value of the basic and target offset forces comprehensively reflects the typical stress level of the isolation system under all working conditions. This parameter can be directly used for simulation testing and performance evaluation, and compared with single level force, it can more comprehensively verify the stability of the isolation system under different seismic intensities.
[0132] Specifically, according to the isolation system information, the monitoring point information is obtained, specifically including:
[0133] According to the isolation system information, obtain the isolation system structure information and the protected equipment information;
[0134] The contact area of the isolation system and the protected equipment is taken as the monitoring basic area;
[0135] According to the seismic stress characteristic points, the projection of the seismic stress characteristic points in the monitoring basic area is taken as the basic monitoring point;
[0136] Based on the protected equipment vibration response distance analysis, obtain the basic monitoring distance information, which represents the minimum distance of the protected equipment vibration response;
[0137] The minimum identification distance of the isolation system stress point is taken as the characteristic monitoring distance;
[0138] Taking the basic monitoring point as the center and the characteristic monitoring distance as the distance threshold, the first monitoring point is generated until the distance between the first monitoring point and the basic monitoring point exceeds the basic monitoring distance;
[0139] After the first monitoring point is generated, the distance threshold is adjusted to the basic monitoring distance to generate the second monitoring point until the second monitoring point covers the monitoring basic area;
[0140] According to the basic monitoring point, the first monitoring point and the second monitoring point, obtain the monitoring point information.
[0141] In this scheme, through structure information fusion, phased point distribution strategy and dynamic distance threshold setting, the precise layout and full-area coverage of the monitoring points are realized in the isolation performance intelligent analysis. The contact area of the isolation system and the equipment is taken as the monitoring basic area, the basic monitoring point is positioned by the projection of the seismic stress characteristic points, which ensures that the monitoring network covers the core parts of stress concentration. The contact area is the key path of force transmission (such as the contact surface between the sliding friction type isolation device and the equipment bottom plate), and the basic monitoring point can capture early failure signals such as interface slip and stress concentration in real time. The seismic stress characteristic points (such as the intersection point of the trend lines of transverse and longitudinal waves) are projected to the contact area, so that the monitoring points directly correspond to the most unfavorable stress working condition. Through the hierarchical application of the characteristic monitoring distance and the basic monitoring distance, a "core encryption-full-area coverage" monitoring network is constructed. The characteristic monitoring distance (such as the minimum identification distance of 50mm of the isolation device stress) is expanded outward from the basic monitoring point, which ensures the high-density sampling (such as arranging 1 point every 100mm) in the key area and accurately captures the local stress gradient change. After the distance between the high-density sampling point and the center point exceeds the limit, the basic monitoring distance (such as the minimum distance of 200mm of the equipment vibration response) is switched to fill the remaining area, which avoids the monitoring blind area and ensures the integrity of the overall displacement field. The monitoring points are upgraded from empirical arrangement to data-driven intelligent planning, especially in the complex equipment isolation scene. The precise positioning and full-area coverage of the key area provide a solid data support for structural safety, equipment protection and operation optimization.
[0142] According to the monitoring point information and the isolation energy consumption coefficient corresponding to each monitoring point, the isolation performance information is obtained based on the simulated earthquake test.
[0143] Specifically, according to the monitoring point information and the isolation energy consumption coefficient corresponding to each monitoring point, the isolation performance information is obtained based on the simulated earthquake test, specifically including:
[0144] Based on the protected device structure analysis, the seismic intensity sensitive interval is obtained, which represents the minimum seismic variation intensity that the protected device can identify;
[0145] The basic isolation level and the target isolation level are taken as the seismic simulation level range, and the seismic intensity sensitive interval is taken as the seismic level change value, and the isolation system is simulated for earthquake test to obtain simulated earthquake test data, the simulated earthquake test data including displacement monitoring data and acceleration monitoring data corresponding to each monitoring point;
[0146] The ratio of the isolation energy consumption coefficient corresponding to each monitoring point to the sum of the isolation energy consumption coefficients corresponding to all monitoring points is taken as the weight coefficient corresponding to the monitoring point;
