【摘要】：集装箱运输是当今物流运输行业的重要组成部分,其中集装箱是存储货物的载体。集装箱在货物装卸和运输过程中需要承受各种各样外力的作用,如何在保证集装箱在货物装卸中和运输过程中的箱体安全的同时提高制造过程的经济性,为企业节约成本,一直是设计人员的研究课题。集装箱需要满足一定的强度、刚度需求,否则在装卸货物、运输货物的过程中一旦发生箱体破损,可能导致货物遗失或损坏,造成较大的经济损失。传统的集装箱设计过程中,在设计完成之后需要造出样箱进行一系列试验台试验,来验证集装箱的安全性。只有通过了这一系列试验才能获准批量生产,否则需要进行再设计和改良,然后再进行样箱试验台试验,直到满足所有的试验要求为止。本文针对传统集装箱设计生产制造过程里设计周期长、设计成本高的现状,提出一种新的设计思路。首先对集装箱进行三维建模,在设计阶段加入有限元分析软件ANSYS,根据集装箱可能遇到的工作环境,进行试验台试验仿真模拟,验证设计方案的安全性、合理性以及经济性。然后根据原设计方案的分析结果找出其中的强度刚度富余、不足的零件部位,再针对这些可能存在的问题进行分析,提出解决办法进行优化设计,并再次用ANSYS软件分析计算,进行验证,直到找到满足安全性、合理性、经济性的新的设计方案为止。并在最后将新设计方案的样箱进行试验台试验,与ANSYS分析结果相对比。以此来达到缩短设计周期、节约设计成本、提高箱体安全性和节约箱体制造成本的目的。得出在设计阶段加入有限元分析软件是适合集装箱制造业的结论。本文对将ANSYS应用于分析各种其他箱型的工程实例具有一定的参考意义。
[Abstract]:Container transportation is an important part of logistics transportation industry, in which container is the carrier of storing goods. Containers need to bear various external forces in the process of cargo handling and transportation. How to ensure the safety of containers in cargo handling and transportation at the same time improve the economy of manufacturing process and save the cost for enterprises. It has always been a research topic for designers. The container needs to meet the demand of strength and rigidity, otherwise, once the box body is damaged in the course of loading and unloading and transporting the goods, it may lead to the loss or damage of the goods, resulting in a large economic loss. In the traditional container design process, after the design is completed, a series of test bench tests are needed to verify the safety of the container. Only through this series of tests can the batch production be approved, otherwise it is necessary to redesign and improve, and then carry out the test bench test of the sample box until all the test requirements are met. In view of the long design cycle and high design cost in the traditional container design and manufacture process, this paper puts forward a new design idea. In the design stage, the finite element analysis software ANSYS, is added to simulate the test bed test according to the working environment that the container may encounter, to verify the safety, rationality and economy of the design scheme. Then, according to the analysis results of the original design scheme, find out the parts where the strength and stiffness are surplus and insufficient, and then analyze these possible problems, put forward the solution to optimize the design, and use ANSYS software to analyze and calculate again. Verify until a new design that meets security, rationality, and economy is found. Finally, the test bench test of the new design box is carried out, and the results are compared with the results of ANSYS analysis. In order to shorten the design cycle, save the design cost, improve the safety of the box and save the manufacturing cost. It is concluded that the finite element analysis software is suitable for container manufacturing industry in the design stage. This paper has a certain reference significance for the application of ANSYS to the analysis of various other box type engineering examples.
