【摘要】：制動(dòng)過程中,低溫運(yùn)輸罐車由于慣性作用會(huì)對(duì)容器壁面產(chǎn)生比較大的沖擊力,必然會(huì)對(duì)低溫運(yùn)輸罐車的安全產(chǎn)生影響。采用流固耦合的方法,以某公司設(shè)計(jì)的低溫運(yùn)輸罐車為研究對(duì)象,模擬罐車從制動(dòng)到停車過程的力學(xué)響應(yīng),得到了沖擊力及封頭壓力隨著時(shí)間的關(guān)系。并對(duì)制動(dòng)過程的低溫運(yùn)輸罐車進(jìn)行了應(yīng)力分析。分析結(jié)果表明:在制動(dòng)開始時(shí),內(nèi)部介質(zhì)對(duì)前封頭的沖擊力達(dá)到峰值,隨后達(dá)到穩(wěn)定值。通過路徑分析得到,該罐車達(dá)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.
