摘　　要：利用有限元法对液罐车制动工况下罐体受力仿真是对其进行优化设计的重要手段。结合等效载荷法对液罐车不同制动加速度下罐体的受力进行仿真,结果表明防波板能够有效地减少液体对罐体的冲击,在满足防波板屈服极限的情况下,充液量为50%时的最大加速度为5 m/s^(2),充液量为65%时的最大加速度为4 m/s^(2),充液量为80%时的最大加速度为4 m/s^(2)。研究结果表明在非紧急情况下根据罐内液体装载量进行合理的制动,可以有效避免罐体损坏,为液罐车罐体优化设计提供理论依据。According to the braking condition of liquid tank truck,the simulation of different braking speeds of liquid tank truck is carried out by using equivalent load method.The simulation results show that the wave-proof plate can effectively reduce the impact of liquid on the cylinder,and the maximum acceleration is 5 m/s^(2) when the yield limit of the wave-proof plate is met.When the filling volume is 65%,the maximum acceleration is 4 m/s^(2).When the filling volume is 80%,the maximum acceleration is 4 m/s^(2).The results show that in the case of non-emergency braking,the reasonable braking according to the liquid load in the tank can effectively avoid the damage of the tank,which provides a theoretical basis for the optimal design of the tank car.
