为进行立筒群仓结构的环境激励测试,以上海粮仓储备库及码头设施项目为工程背景,设计了2×3个单仓组成的群仓试验模型。通过对试验模型进行有限元模态分析,总结模型各阶振型的规律和特点。以优化测点数目为原则,结合模型的对称性,确定了模型的最优测点布置方案和传感器的测试方向。根据模型各阶振型特点,测试前对测点进行最优组合,从而确定测点分批测试方案。 In order to test the environmental incentive test of the silo structure, the warehouse test model of 2 × 3 single silos was designed with the project of Shanghai granary storage and dock facilities as the engineering background. Through the finite element modal analysis of the experimental model, the regularities and characteristics of each mode shape of the model are summarized. Based on the principle of optimizing the number of measuring points, combined with the symmetry of the model, the optimal layout of the measuring points and the testing direction of the sensor are determined. According to the characteristics of each mode of the model, the optimal combination of measuring points before the test, so as to determine the measuring point batch test program.
