【Abstract】 Through the study of mechanics and mathematics models of construction machinery frame, the finite element anaysis system(CSFAS) of construction machinery frame in micro computer is developed, the constraint distorsion of space thin walled elements is induced in this system, compared with other software, the calculation results of the system are more accurate than that of practical situation.更多还原
