Abstract


Natural structure of bamboo makes bamboo has good mechanical properties , the hollow with section to bending ability , section spacer to increase the overall bamboo transverse compressive strength . Traditional bamboo processing and utilization are a lot of cutting and crushing processing , mechanical properties of the destruction of a bamboo natural hollow with a compartment structure , and the pursuit of the physical part of the use of bamboo wall . Spliced ??into a variety of hollow puzzle forming simple premise does not destroy the natural structure of bamboo , bamboo , \In this paper trails of forming bamboo processing technology and molding bamboo segment mechanical properties , mainly including the following three aspects : (1) the experimental test bamboo segment quadrangular forming trails bamboo mechanical properties , explore the use of natural hollow with every bamboo unit stitching hollow bamboo puzzle feasibility . (2) forming four prism bamboo segment radial compressive and flexural stress finite element simulation analysis , to study the Bamboo paragraph radial compression and flexural possible failure modes . (3) compare the of existing bamboo segments forming methods , analysis of the problems of existing processing methods , raised the bamboo segment pull whittled method , developed a natural hollow with every bamboo of pull the whittled -type technology and broaching tool , and the trails bamboo pull whittled experiment . Through research, to draw the following conclusions : ( 1) forming , bamboo internode radial compression , longitudinal bending capacity weakened , but weakened slightly ; its opposite with a section of bamboo radial compression capability has been enhanced. ( 2) the use of ANSYS software , the qualitative simulation Bamboo radial pressure , longitudinal bending stress - strain distribution , a destruction of the pre- test results and experimental destruction agreement . ( 3 ) of this article developed trails bamboo pull whittled technology with high production efficiency , product quality , lower energy consumption , there are good prospects for development . (4 ) multi- blade circular sawing machine the pressure the straight sawing pull whittled type is the dwarf bamboo molding feasible technology program .
