| Abstract: | Based on the engineering practices this article presents several simplified and practical methods to calculate the natural frequency for the beam.The principle of methods is equivalently transfer the complex mass on beam to uniform or point mass located in any position or located in certain position on beam.According to the engineering practices,using the method here to calculate natural frequency can meet the requirement of engineering. |
| Keywords: | Natural frequency Complex mass Simplified method Calculation |
