Abstract：Inorderto solve the problems ofbalesurface layer damage，material scatering，and lowbale density during the baling process ofsilagecorn，andtoobtain theoptimalcompresiondensity-time combinationof silage bales，a balingand wrapping machineofsilagecorn wasdesigned．Byanalyzing theimpactof theinitial densityofthesilagebaleonits adhesion coefficient， it was found that when the compressed density of silage corn was 960kg/m3 ，the adhesion coefficient reached the maximum value of 144kg/（m⋅s） and the nutrient loss of the silage material was minimal. Through optimized designandanalog simulationanalysis of the baling steelroller，it was concludedthattheconvolution pressreof the smooth roller，rib steel roller，and herringbone steel roller on the grassblades were 403.5kPa ， 410.4kPa and 432.5kPa （204 respectively. In addition，according tothe displacementand deformationof the grass blades，the warpage amplitudes of the smooth roller，rib steel roller and herringbone steel roller when convolving the grass pieces were 130.7mm ， 89.81mm （204号 and 84.42mm respectively.Finally，through thereliabilityanalysisof the herringbone steel roller，it wasverified that the structuralstrengthofthe heringbone steelroller wasreliable.Basedonthe sizeofthe silage bale，the diameterof the steel rollerandthe sizeoftheaditionalmechanism，thesimulink controlsystem forthebaling bin，rope knoter，baletemporary storagestationand operation stationwas designed.Intheend，through thewholemachine test，it was concluded that when the operating time and baling density were 122s and 960.3kg/m3 respectively，the ideal compression density was closesttotheadhesioncoeficientanalysis，andthe minimum nutrient lossofsilagecorn wasobtained，and the settig value ofthe Amesim hydraulic control system sensor was calculated as 101.7MPa Keywords：corn silage；baling and wrapping machine；herringbone steel roller；compresson baling；automatic wrapping
