The damage of structure and technical performance of vehicle were affected by the impact at landing process of airborne. For researching the cumulative damage of airborne vehicle under impact, airdrop tests would consume lots of manpower and material resources. So numerical simulation offered one of available means for this problem. Based on the finite element model of vehicle and airbags, the calculation and assessment method for cumulative damage under landing impact time after time was proposed. The creditability of finite element model was validated by airborne test under typical condition. Associated with Lemaitre damage model and the damage evolution law of the material, the cumulative damage of the structure of vehicle was calculated. The results would provide theoretical reference and technical guidance for the design and maintenance of the airborne vehicle.
