The invention discloses a rubber and plastic seal friction energy consumption and online intelligent detection analog system. The system comprises a suspension pipe sub-assembly, a transparent pipe section, an electro-hydraulic vertical injection assembly, a twisted-pair flexible hollow shaft, an electromagnetic shock excitation assembly, an image collection assembly, an infrared camera-shooting assembly, an optical supporting platform and a section bar frame, wherein the suspension pipe sub-assembly is mounted inside the section bar frame, and an optical fiber sensing network is arranged on the peripheral surface of the suspension pipe sub-assembly; the transparent pipe section is connected with the lower end of the suspension pipe sub-assembly through a snap joint, and a dirt medium is spread on the inner wall of the suspension pipe sub-assembly and the inner wall of the transparent pipe section; the electro-hydraulic vertical injection assembly is mounted on the top inside the section bar frame, and the top end of the twisted-pair flexible hollow shaft is clamped by the electro-hydraulic vertical injection assembly. The system can be used for simulating the dynamic testing device of a complex seal friction system consisting of a sealing bowl, a pipe inner wall and a dielectric material under a robot site service black-box environment.
