摘要

为明确MTC装置力学性能及设计参数影响的一般规律，针对力学性能开展拟静力试验研究，并采用有限元模型进行验证分析，在此基础上基于正交试验设计开展MTC装置初始刚度参数影响显著性分析，并探究MTC装置初始刚度在显著性参数影响下的变化规律。结果表明，考虑装配间隙调整后有限元与试验所得连接刚度较为一致，所建有限元模型可反映MTC装置连接刚度实际变化情况；MTC装置初始刚度参数影响显著性顺序为耗能挡板高度、厚度、短底边长度、长底边长度、挡板间距；耗能挡板高度、厚度及短底边长度为影响MTC装置初始刚度的显著性参数，利用MTC装置进行连续梁桥抗震设计时可适当改变三者取值对装置初始刚度进行调整，以实现理想减震效果。

Abstract

In order to elucidate the mechanical performance of the MTC device and confirm its usual change rules under the influence of the related design parameters, the pseudo-static test was carried out and verified by finite element models for the mechanical properties. The method of orthogonal test design was utilized to analyze the significance of the design parameters. The changing laws of the initial stiffness under the impact of significant design parameters were analyzed. The results show that the finite element analysis results are consistent with the test connection stiffness after the adjustment considering the assembly clearance. The finite element model can reflect the actual variation of connection stiffness of the MTC devices. The significant order of the design parameters affecting the initial stiffness of the MTC device is the height, the thickness, the length of the short bottom edge, the length of the long bottom edge and the separation distance of the energy-consuming plates. The height, the thickness and the length of the short bottom edge are the significant parameters affecting the initial stiffness of the MTC device. The initial stiffness of the device can be adjusted by changing their values to achieve the ideal damping effect when the MTC devices are used in the seismic design of a continuous beam bridge.
Key words: MTC device; mechanical performance; initial stiffness; design parameters; orthogonal test; parameters analysis
