Due to the structural characteristics of the long and slender horizontal hydraulic cylinder, it is prone to flexural deformation and instability under the effect of its own gravity and axial load, which may cause great safety hazards. This paper aims to design a test platform suitable for the flexural stability test of long and slender horizontal hydraulic cylinders. First of all, the model of large hydraulic cylinder is scaled down according to the modeling theory. The calculation method and finite element analysis method are used to simulate the deflection of the model, while simulating, the model hydraulic cylinder is regarded as the stepped rod. According to the calculated results, the overall scheme of the test platform is designed. And further, the platform structure design is completed. Finally, the finite element analysis software is used to assist the strength check. Through the design calculation and strength check in the paper, a hydraulic cylinder deflection test platform suitable for different strokes and bore diameters. The structure of the test platform is stable and reliable, and it is also convenient for assembly and disassembly.
