Study on Vibration Reduction Technology for Transportation of TEG Dehydration Unit Regeneration Module 2021-01-0334

In the petroleum and gas industry, cargo truck is one of the most important ways to transfer the skid-mounting from the manufacturer to the job location. Under the condition of bumpy road surface, the random vibration from the ground can easily cause the resonance of the internal equipment components of the skid-mounting, produce large deformation in the pipeline and equipment connection, and even the equipment will be damaged. In this paper, the finite element analysis model and dynamic rigid flexible coupling model of a TEG (Triethyleneglycol) dehydration unit regeneration skid-mounting are established by using the finite element analysis and multi-body dynamics software. The modal analysis of the skid and the vibration of the whole vehicle under different road excitation and driving conditions are carried out. Two solutions are proposed to improve the anti-vibration ability of the skid, and comparative analysis is made. One is to increase the local strength by adding pipe support in the weak place; another one is to add vibration isolation between the skid base and the truck frame to reduce vibration. The results show that the strength can be improved by adding pipe support locally, and the vibration condition of the skid is obviously improved after adding vibration isolation. The risk of damage to skid due to vibration is reduced.
