HOW TO DESIGN A HYDRAULIC CYLINDER IN CREO USING TOPDOWN ASSEMBLY METHOD-PART 1
CREO RELATIONS FORMULAS
WORKING_PRESSURE = 0.0101972*W_PRESSURE
AREA = (FORCE/WORKING_PRESSURE)
CYL_ID = sqrt((AREA*4)/(pi))
CYL_THK = (CYL_ID/2)*(sqrt((WORKING_STRESS+WORKING_PRESSURE)/(WORKING_STRESS-WORKING_PRESSURE))-1)
NUT_DIA = PISTON_ID + 0.5*PISTON_ID
PISTON_THK = (CYL_ID/2)
PLATE_THK = (CYL_ID)*(sqrt((3*WORKING_PRESSURE)/(16*WORKING_STRESS)))
PLATE_OD = CYL_ID+(2*CYL_THK)
PLATE_ID = CYL_ID
SEAL_BOX_THK = sqrt((1.88*FORCE)/(WORKING_STRESS*2))
SEAL_BOX_OD = CYL_ID+(2*CYL_THK)
SEAL_BOX_OUTER_THK=CYL_THK
NUT_THK = 0.5*PLATE_THK
CYL_LENGTH = SEAL_BOX_THK + SEAL_BOX_CUS_THK + STROKE + PISTON_TKH + NUT_THK + PLATE_THK
ROD_EXT = (STROKE/10)
ROD_LENGTH = ROD_EXT + STROKE + PISTON_TKH + NUT_THK+SEAL_BOX_OUTER_THK+SEAL_BOX_THK+SEAL_BOX_CUS_THK
SEAL_BOX_CUS_THK = NUT_THK
a=1/7500
b =(1+a*(ROD_LENGTH*ROD_LENGTH))/(WORKING_STRESS*pi)*(64*FORCE)
ROD_DIA =sqrt( sqrt(b))
NUT_ID = PISTON_ID
SEAL_BOX_CUS_OD = ROD_DIA + (0.5*ROD_DIA)
Повторяем попытку...
