| Abstract: | Objective To validate the designed strength of the body frame of some advanced ICU ambulance to provide references for following improvement. Methods 3D model of the ambulance was established, and finite element analysis software was used to analyze the conditions of bending, twisting, turning, braking and etc. Results The mean stress of the body frame was less than the yield strength of the material, with the minimum safety factor of 1.43. Conclusion The body frame of the advanced ICU ambulance can meet the desired requirements. |
