Embodiment Construction

[0014] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the heave simulation test bench driven by bilateral hydraulic cylinders of the present invention includes a test bench frame 1, a heave hydraulic cylinder 3, a guide rail slide table, and a connecting mechanism, and the components are arranged symmetrically on opposite sides. The above-mentioned test bench frame 1 is arranged horizontally, and is used for loading and fixing the test object. The guide rail slide table 2 is used to carry the load provided by the heave hydraulic cylinder 3 and transmit the heave action to the test bench frame 1 . The heave hydraulic cylinder 3 is connected with the guide rail bottom plate 12 through the hydraulic cylinder support seat 5 . The connection mechanism includes a hydraulic cylinder support seat 5, a slide table side bearing seat 6, a connecting shaft 7, and a frame side beari...

Abstract

The invention discloses a heaving simulation test bed driven by bilateral hydraulic cylinders. The heaving simulation test bed comprises a test bed frame, a guide rail sliding table, a heaving hydraulic cylinder and guide rails, wherein the test bed frame is rectangular, is horizontally arranged and is used for loading and fixing a tested object; the vertical guide rails are symmetrically arrangedon the left side and the right side of the test bed frame, and the guide rail sliding table and the heaving hydraulic cylinder which are connected up and down are arranged in the guide rails; the guide rail sliding table is used for bearing a load provided by the heaving hydraulic cylinder and transmitting heaving action to the test bed frame; and the heaving hydraulic cylinder is connected witha guide rail bottom plate through a hydraulic cylinder supporting seat. The test bed can reproduce the real stress condition of the shipborne equipment when the shipborne equipment is subjected to heaving load, and then a reliability simulation test is carried out.

Description

technical field [0001] The invention belongs to the technical field of simulation test benches, and relates to a heave simulation test bench driven by bilateral hydraulic cylinders. Background technique [0002] When the ship is sailing, it will be turbulent due to the fluctuation of the water surface. Due to the turbulence of the hull, the ship-borne electromechanical equipment will be subjected to corresponding loads when it is working, which will affect its working reliability. At present, many reliability simulation tests using land test benches generally only simulate the working environment of ship-borne electromechanical equipment, including factors such as temperature and humidity, and seldom consider the additional load on the equipment due to the movement of the hull, resulting in deviations between the simulation results and the actual results. . [0003] At present, equipment related to heave motion has a wide range of application scenarios. For example, CN20847...
