【摘要】：制动过程中,低温运输罐车由于惯性作用会对容器壁面产生比较大的冲击力,必然会对低温运输罐车的安全产生影响。采用流固耦合的方法,以某公司设计的低温运输罐车为研究对象,模拟罐车从制动到停车过程的力学响应,得到了冲击力及封头压力随着时间的关系。并对制动过程的低温运输罐车进行了应力分析。分析结果表明:在制动开始时,内部介质对前封头的冲击力达到峰值,随后达到稳定值。通过路径分析得到,该罐车达到安全要求。
[Abstract]:During the braking process, the low temperature transport tank car will have a relatively large impact on the container wall due to inertia, which will inevitably affect the safety of the low temperature transport tank car. The fluid-solid coupling method was used to simulate the mechanical response of a low-temperature transport tank car designed by a company from braking to parking. The relationship between impact force and head pressure with time was obtained. At the same time, the stress analysis of the low temperature transport tank car during braking process is carried out. The results show that at the beginning of braking, the impact force of the internal medium on the front head reaches the peak value and then reaches the stable value. Through the path analysis, the tank car meets the safety requirements.
