The invention relates to a test device for determining parameters of steam explosion technology, belonging to physics test equipment. In the current technology mode, which realizes steam explosion through fast valve opening, long pressure release time reduces the energy density, so the material decomposition degree is low, little facilitating later enzymatic hydrolysis. The technological test bench based on the principle of cylinder explosion piston provided by the invention can finish the steam explosion within milliseconds, improving the energy density and fully decomposing the material. The technical principle of the test bench is also reflected in the design of industrial steam explosion devices, which accurately simulates the production environment for future industrialization of steam explosion and, thereby, accurately determining parameters of the steam explosion technology and providing fiber pretreatment materials for metaphase experiments of biochemical treatment such as enzymatic hydrolysis and the
