| Abstract: | Several troubles of cracking in the hanging sills for oil tanks on generator cars are described. According to causes to cracking and the finite element strength calculation, the reinforcement scheme of the hanging sills for oil tanks is put forward. In order to further demonstrate the calculation result, the real-car dynamic stress testing is made on the original structure and reinforcement structure, and the evaluation of the fatigue strength is carried out. |
