SolidWorks 仿真工程师云计算：General Contact
SOLIDWORKS在3DEXPERIENCE平台上推出一款新产品：结构仿真工程师。 什么是结构仿真工程师？ 它是由Abaqus提供的有限元分析应用程序，Abaqus是市场上最好的非线性求解器。 结构仿真工程师将SOLIDWORKS Simulation功能扩展到更先进的非线性解决方案：大变形和大应变，稳健接触，各种非线性材料模型，四边形和六边形网格以及云计算。在这个产品的许多令人兴奋的功能中，先介绍General Contact。General Contact allows users to define contact between all or multiple regions of a model. The software recognizes those components that mate as a single interaction where anything can hit anything. As a result, it will automatically determine and enforce contact compatibility between components.
Figure 1 illustrates how the interaction between 3 parts are treated as a single contact domain
Figure 2 shows General Contact being automatically created when model is imported from SOLIDWORKS into Structural Simulation Engineer. All contact pairs between components are treated as one single contact domain
Fig 3. Contact Pair is the alternate method (define 6 contact pairs)
Figure 4 shows a Contact Pair being generated using the Contact Pair method between the top metal plate and the rubber bumper. For this simulation model, we will need to define a Contact Pair between the bottom plate and the rubber bumper and other Contact Pairs to include all surfaces of the rubber part that will self-contact with each other as illustrated in Figure 3.
General Contact is an efficient way to get the software to find and determine where contact occurs. General Contact will save you a ton of time, especially when working with models that have many complex contacts.
Another benefit is it will increase the accuracy of your model. This is particularly helpful when models are going through large deformation, large strain or when they are self-contacting.
An example of self-contact is shown in Figure 5 where, using General Contact, users don’t have to predict, select and organize which surfaces will come into contact with any other surfaces before running the analysis.
