摘要
介绍了一种计算开裂简支梁自振频率的方法,用无质量抗转动弹簧描述裂缝的影响,该方法可以求出带多个裂缝简支梁的自振频率。并采用通用有限元程序ANSYS进行了验证分析,给出了裂缝位置及裂缝深度对简支梁自振频率的影响规律。
It introduces calculating method for natural vibration frequency of brief-beam, which simulating influencing of crack applying for noquality rotary spring, and it can calculate natural vibration frequency of brief-beam with many cracks, then it obtains influencing rule on location ＆ depth to natural vibration frequency of brief-beam and applying for ANSYS to prove it.
