Element先进的有限元分析(FEA)和建模服务支持产品开发, simulation of service conditions, design optimization, life prediction, fitness for service, and failure analysis.  我们的专家与传统的测试服务合作,分析复杂结构和系统的强度, determine component behavior, 准确预测产品在结构和热负荷下的反应. 

 

What is finite element analysis (FEA)?

有限元分析使用一系列数学模型来模拟一个零件或一组零件在预先定义的一组条件下的反应或行为.

 

What are the types of FEA analysis?

有限元法可用于求解工程连续介质力学的任何方程, including fluid flow, acoustics, and electromagnetics, 但最常用于求解应力和应变方程.  We use static FEA to solve for strength and integrity, and dynamic FEA to solve for impact, explosions, and penetration.

 

What are the advantages of FEA?

有限元分析自20世纪60年代以来一直在使用,是一种精确计算结构在荷载作用下的应变应力的行之有效的方法.  现代计算能力现在允许我们考虑复杂的设计和材料组合在巨大的不同负载条件下.  Multiple failure scenarios can now be examined safely and quickly, without the expense of full-scale test apparatus.

 

Applications of FEA

We use FEA for a wide range of different applications:

  • 我们用它来计算航空航天中高载荷部件的应力, nuclear, defence, medical, chemical and offshore industries to identify the risks of failure.
  • 扩展的有限元分析方法可以用来明确地模拟裂纹的扩展,以预测失效时间.
  • 本文采用动态有限元分析方法研究了燃气轮机叶片失效及叶片是否会穿透发动机周围的保护机匣等情况.
  • By coupling with acoustic or flow solvers, 我们可以计算化学过程系统中由高频振动引起的应力, and hence their fatigue lives.
  • 我们使用相同的基本方法来计算海底设备的表面电势,以优化被动或主动阴极保护系统的设计.
