摘　　要：利用标准振源对振动加速度信号在频域进行滤波并积分后求得振动位移的方法进行验证,确认了方法的可行性与可靠性。对某闸门进行了振动加速度、位移和动应力等振动响应测试,测试部位振动加速度均小于3 m/s 2,振动位移小于0.25 mm,动态应力小于153.2 MPa,闸门起升初始阶段振动位移最大值超过相关要求。结合加速度、位移和动应力给出闸门的振动评价。The standard vibration source is used to verify the method that the vibration displacement is obtained by filter and integral in frequency domain,and the feasibility and reliability of the method is confirmed.The vibration response such as acceleration,dynamic stress and displacement of a gate in a hydropower station are tested.The test results show that the vibration acceleration is less than 3 m/s 2,the vibration displacement is less than 0.25 mm,and the dynamic stress is less than 153.2 MPa.In the initial stage of gate lifting,the maximum vibration displacement is over the requirements of standards.Based on the test results of acceleration,displacement and dynamic stress,the vibration characteristic of gate is evaluated.
