The disclosure provides a distributed load impact reliability test device. The distributed load impact reliability test device comprises a test bench, a cylindrical member, a loading member and a driving mechanism. The test bench is used for bearing a test piece. The cylindrical member is provided with a cavity which is communicated along a preset direction, and one end of the cavity can be in sealing connection with the surface, far away from the test bench, of a test piece. And the loading member is in sliding sealing fit with the inner wall of the cavity, so that a sealed space capable of accommodating liquid is formed in an area, between the test piece and the loading member, of the cavity. And the driving mechanism is used for applying an impact load towards the test piece to the loading member. The distributed load can be quickly applied to the test piece, and the accuracy of a detection result is improved.
本公开提供一种分布载荷冲击可靠性试验装置。所述分布载荷冲击可靠性试验装置包括试验台、筒状构件、加载件以及驱动机构。所述试验台用于承载一试验件。所述筒状构件设有沿预设方向贯通的空腔,所述空腔的一端能够与所述试验件远离所述试验台的表面密封连接。所述加载件与所述空腔的内壁滑动密封配合,以使所述空腔位于所述试验件和所述加载件之间的区域形成一能够容纳液体的密封空间。所述驱动机构用于对所述加载件施加朝向所述试验件的冲击载荷。本公开能够快速地对试验件施加分布载荷,提高了检测结果的准确性。
