摘要
基于一维波动理论,通过理论分析,推出了两端自由,一端固定一端自由,一端自由一端弹性支撑时锚杆的位移、速度、加速度响应;同时得出了基频、波速和锚杆长度之间的定量关系,并在实验室对不同约束下锚杆的加速度响应进行了测试.
Based on one-dimensional wave theory,the response of displacement and s peed and acceleration about bolt in d ifferent restriction are concluded.At the sa me time,the relation between wave sp eed and basic frequency and bolt length is found out.The response curve of acceleration in different state is tested at la boratory.
