This method, however, suffers from the sensitive variation of the intensity to the ground material, which makes a relatively low accuracy of the DEM reconstruction, e.g., about 50m for the ERS SAR.

With the development of mechanism and technology science, if the controllable mechanism technology is applied in the field of construction machinery, great development and progress will be offered to construction machinery. 1 Build a three-dimensional model of the work equipment This paper is relates to the work equipment of the multi-DOF controllable mechanism type loader, which linkage mechanism is used to transported power rather than hydraulic transmission system.
Then, define the material of the model and the constraint between the parts.

As a reinforced materials of modified concrete, the natural organic fiber is one of the hottest research fields in China at present.
In the south of China, especially in Guangxi province, where is rich in sisal plants, they can use local materials conveniently.
Admixture: TH-W5 water reducing admixture, produced by Hengda Materials Co., LTD, can reduce water consumption about 15%~25%.
Concrete is a kind of heterogeneous material, because of its internal hydration reaction, the volume of materials shrink in general, therefore the shrinkage of different materials produce different stress, which cause many tiny cracks of concrete to appear.
