|
Abstract:
为了研究不同材料混合的复合材料性质以及不同应用场景下的复合材料实际应用性能，需要对复合材料进行研究测试，设计一款适用于复合材料层合板的双轴拉伸-压缩试验机。该试验机通过夹具体对复合材料层合板进行精准定位加紧，双轴分别用伺服电机驱动滚珠丝杠带动负载，完成对材料的拉伸和压缩测试。设计出双轴试验机整体结构并绘制出三维模型和二维平面设计图纸。通过有限元分析软件对整体结构进行关键部位校核，最后分析结果表明，双轴试验机结构设计合理，并且能达到承受最大负载50 KN的能力，满足设计要求。
In order to study the properties of composite materials mixed with different materials and the actual application performance of composite materials under different application scenarios, it is necessary to research and test the composite materials and design a biaxial tensile compression testing machine suitable for composite laminates. The tester is used to precisely position and tighten the composite laminates by clamping, and the two axes drive the load with the ball screw driven by the servo motor to complete the tensile and compression tests of the materials. This project designs the overall structure of the biaxial testing machine and draws the 3D model and 2D plane design drawings. The key parts of the overall structure are checked by the finite element analysis software. The final analysis results show that the structure design of the biaxial testing machine is reasonable and can withstand the maximum load of 50 KN, meeting the design requirements.
