Composite material long beam strength test device

The invention belongs to the technical field of composite material tests, and particularly relates to a composite material long beam strength test device. The device includes a long beam fixing device (1), a loading device (2), an actuator fixing device (3), a long beam lateral restraining device (4) and a supporting frame (5). According to the invention, the clamping ends at the two ends of the test piece can uniformly bear the load, and meanwhile, the influence on test loading caused by large bending deformation of the long beam after loading is avoided, the test loading direction is ensured, and the accuracy of the test result is improved; the roller diameter is designed according to the predicted deformation of the test piece, so that the loading direction is vertical to the test piece, and the test piece is uniformly stressed; by means of the actuator fixing device, it is guaranteed that the position and direction of the applied load are accurate. 本发明属于复合材料试验技术领域，具体涉及一种复合材料长梁强度试验装置。包括长梁固定装置(1)、加载装置(2)、作动
