Abstract

Risk of fatigue failure exists in the tube trailer cylinders under the condition of internal pressure variation and inertial load caused through road transport.In order to estimate the safety state of the cylinders under the action of alternating load,the model of certain geometry sizes is built based on the widely used tube trailer cylinders.The fatigue analysis of tube trailer gas cylinders is made aiming at the action of the internal pressure and the inertial load.The fatigue life distribution of cylinders is obtained under the condition of different loads through the numerical simulation by ANSYS Workbench.The analysis results show that under internal pressure,gas cylinders have limited fatigue life,but can satisfy the requirements;when the inertial load exceeds a certain value,natural gas cylinders of tube trailer is under finite life state,which does not meet the requirements of strength,therefore the inertial load should be controlled.

管式拖车气缸疲劳寿命分析

在公路运输引起的内压变化和惯性载荷作用下，管式拖车汽缸存在疲劳失效的危险。为了估计在交变载荷作用下气缸的安全状态，以广泛使用的管式拖车气缸为例，建立了一定几何尺寸的模型。针对内压和惯性载荷的作用，对管式拖车气瓶进行了疲劳分析。通过ANSYS Workbench的数值模拟，得到了不同载荷条件下气缸的疲劳寿命分布。分析结果表明，在内压作用下，气瓶的疲劳寿命有限，但能满足要求;当惯性载荷超过一定值时，管式拖车天然气气瓶处于有限寿命状态，不满足强度要求，应控制惯性载荷。
