Abstract:
In order to provide some theoretical basis for design of cutting mechanism of
Ficus microcarpa 'Golden Leaves' and establish finite element mechanical model of
Ficus microcarpa 'Golden Leaves', it is necessary to study mechanical properties of
Ficus microcarpa 'Golden Leaves'.
Ficus microcarpa 'Golden Leaves' was used as experimental material to measure its moisture content, and radial compression, axial compression, three-point bending and shear tests were carried out.Results showed that average radial compressive elastic modulus of treetop part, upper part and middle part were 65.27, 80.01 and 118.30 MPa, respectively.Average axial compressive elasticity modulus were 20.64, 22.78 and 26.72 MPa, respectively.Average flexural elasticity modulus were 120.10, 180.34 and 221.56 MPa, respectively.Minimum shear strength of middle part was 5.60 MPa and maximum was 16.95 MPa.It was found that the maximum load of branches in the same position decreased with increase of water content, so sprinklers could be added to design of hedgerows or pruned when there was a certain humidity of
Ficus microcarpa 'Golden Leaves'.
