| Abstract: | The theories and methods of finite element and transient dynamics are used to study the safety of post-collision mobile pressure vessel. The physical model of mobile pressure vessel transporter is established by using Solidworks 3D-modeling software,and then pre-treat analyses are performed by ANSYS finite element anal- ysis software and LS-DYNA transient dynamic software. The dynamic impacting stress response of vehicle frame,pressure vessel, combined supports and other auxiliary components is obtained at the speed of 60 km/h. The re- suits show that though vehicle frame and connecting bolts are destroyed, the impact to pressure vessel is effec- tively decreased. The safety of pressure vessel is guaranteed and these analyses provide theoretical supports for fu- ture optimization design. |
