Analyzing the Natural Frequency of Litchi Tree

Abstract:

The aim of the investigation is to analyze the natural frequency of litchi tree. The litchi tree was simplified into a cantilever beam with a concentrated mass attached at the free end. Equivalent mass equation and stiffness equation were established to calculate the natural frequency. Effect of canopy mass, trunk length, bottom radius of trunk, and top radius of trunk to the natural frequency of litchi tree was analyzed. The analysis results showed that natural frequency decreases with canopy mass and trunk length, and increases with bottom radius and top radius of the trunk. And in a conventional trunk radius, length, and canopy mass range, the natural frequency in cycles of the litchi tree is between 0.5-5Hz.
