摘要
现有碳纤维复合材料传动轴通常由金属法兰与碳纤维复合材料轴管组成,金属法兰因其质量大,且需采用胶接或铆接形式与轴管进行连接,会增加启动或制动时的惯性,影响整体性能。因此,开展了法兰轴管一体成型的全碳纤维复合材料传动轴制备与扭转试验研究,采用轴管卷料及法兰翻边与环包工艺制备全碳纤维复合材料传动轴,其全长为1980 mm,传动轴铺层方案为[(±45°)32/45°],然后进行了静扭试验及扭转疲劳试验验证。由试验结果可得,全碳纤维复合材料传动轴在12000 N·m静扭试验下,未发生破坏,测得其扭转刚度为1.93×10^(5)N·m/rad;全碳纤维复合材料传动轴在20万次扭转疲劳试验中未发生破坏,满足正常工作要求,扭转疲劳试验中最大剩余扭转刚度为2.02×10^(5)N·m/rad,最小剩余扭转刚度为1.89×10^(5)N·m/rad。
The existing carbon fiber composite drive shaft is usually composed of metal flange and carbon fiber composite shaft tube.The metal flange has heavy weight and needs to be connected to the shaft tube by adhesive bonding or riveting,so it can increase the inertia during starting or braking and affect the overall performance.Therefore,the preparation and torsion test research of all-carbon fiber composite drive shaft with flange and shaft tube integrated molding were presented.The all-carbon fiber composite drive shaft was prepared using the tube coiling and flange flanging and wrapping process,the total length of the drive shaft was 1980 mm,and the layering scheme was[(±45°)32/45°].At last,the static torsion and torsional fatigue tests were conducted.According to the test results,the all-carbon fiber composite drive shaft has no damage under 12000 N·m static torsion test,and its torsional stiffness is 1.93×10^(5) N·m/rad.No damage occurs in the torsional fatigue tests with 200000 times,which met the normal working requirements.The maximum residual torsional stiffness in the torsional fatigue test is 2.02×10^(5) N·m/rad,and the minimum residual torsional stiffness is 1.89×10^(5) N·m/rad.
