description The invention discloses a sine wave waveform combined compensation method for an arresting impact test, which is characterized by comprising the steps of 1, adding a half-sine wave in front of an original arresting impact waveform to perform speed compensation so as to enable the acceleration amplitude and the table top displacement to be the minimum; 2, adding a complete sine wave in front of thecompensated waveform to perform displacement compensation so as to enable the speed and the acceleration of the table top of the vibration table to be both 0; and 3, carrying out a test according tothe combined waveform after two times of compensation. According to the invention, an arresting impact test can be carried out on part of vibration tables whose speed and displacement do not meet testconditions. 本发明公开了一种用于拦阻冲击试验的正弦波波形组合补偿方法，其特征在于包含以下步骤：步骤一、在原始拦阻冲击波形前增加一个半正弦波进行速度补偿，使加速度幅值和台面位移最小；步骤二、再将补偿后的波形前增加一个完整正弦波进行位移补偿，使振动台台面速度和加速度均为0；步骤三、按两次补偿后的组合波形开展试验。本发明可在部分速度、位移不满足试验条件的振动台实施拦阻冲击试验。
