To solve the skin cracking problem of a bus top cover,this paper presents a solution that takes the relative displacement change rate of the bus body skeleton opening diagonal as the evaluation index under eight typical operating conditions.The optimal design of the bus body skeleton structure is carried out by preliminary calculation and the combination of the adaptive response surface method.Under the no-gaining weight situation,the relative displacement change rate of the skeleton opening diagonal is less than 0.2%,and the skin does not crack again.
