Aiming at the problems of low mechanical efficiency and high peeling damage rate of peeling equipment in the harvesting process of fresh corn in China, based on the analysis of the structural characteristics of the existing peeling device, a flexible peeling device with the combination of “flexible segmented roller type + spiral adjusting frame” and rubber frequency vibration plate matching was designed. According to the physical characteristics of fresh corn, the peeling process of fresh corn was analyzed mechanically and kinematically, the main factors affecting the peeling performance were determined, and the structural design and parameter analysis of the peeling device was carried out. ANSYS Workbench/LS-DYDA module was used to simulate the peeling process of fresh corn ear, and a peeling prototype was fabricated according to the theoretical analysis and simulation results, and the peeling test was carried out. In order to obtain the best test material for the prototype, a single-factor test was conducted with cob length, ear diameter and ear water content as test factors, and ears with length of 260~280mm, diameter of 64~66mm, and water content of 66.5%~69% were determined as samples for the orthogonal test material of the peeling machine. Design-Expert software was used to design a three-factor, three-level orthogonal test, with peeling roller speed, peeling roller inclination angle and vibrating plate vibration frequency as test factors, and bract peeling rate and grain breaking rate as test indicators. The results showed that the impact on bract peeling rate and grain breaking rate from large to small were peeling roller speed, peeling roller inclination angle, frequency vibration plate; the optimal combination of parameters: peeling roller speed of 478.72r/min, peeling roller inclination angle of 8.05°, vibrating plate vibration frequency of 259.20 times/min, at this time, the bract peeling rate was 92.41%, and the grain breaking rate was 1.47%. Under this condition, the verification test was carried out according to the actual working conditions, and the bract peeling rate and grain breaking rate were 91.75% and 1.55%, respectively, which were basically consistent with the parameter optimization and met the requirements of fresh corn peeling. The research result can provide technical support for the optimal design and selection of fresh corn peeling equipment. 
