为研究工程结构材料的动态力学性能和失效机理,提出一种模拟浪溅区波浪冲击动态力学性能检测的新方法,并针对该方法设计一种实现波浪冲击动态应变检测的自动化装置。以690 MPa高强钢试件为对象,使用该装置检测其在不同浪速、不同作用时间和不同冲击方向的波浪冲击作用下的动态应变,实验结果符合理论分析,证明该装置准确可靠,为研究波浪冲击动态应变作用机理提供一种新的实验方法。

A new detection method for simulating the dynamic strain of wave impact in the splash zones was presented to estimate dynamic properties and failure mechanism of materials used in engineering structures. Moreover, an automatic device was designed to detect the dynamic strain based on the method. The test was performed using 690 MPa steel as the test object. Its dynamic strain processes were detected under the waves of different angles and velocities. The experimental results are consistent with the theoretical analysis and indicate that the device is accurate and reliable,and has provided a new experimental method for the dynamic strain mechanism of wave impact.
