Finite Element Analysis (FEA)

GMORS uses finite element analysis (FEA) to assist customers in the evaluation of problems in relation to the use of seals.

GMORS uses finite element analysis (FEA) to assist customers in the evaluation of problems in relation to the use of seals, as well as in the optimization of seal design and development of new seals. The method used in FEA is to divide the seal to be analyzed into a finite unit element, and define the boundary conditions according to the operating conditions of the seal. CAE computer software is then used to perform high speed calculations to simulate seal deformation based on the defined boundary conditions. The results of the stress interactions acting on the seal are visually presented to the user.

GMORS FEA has the following advantages

  • Reduces the time and cost associated with new product development.
  • Assist customers to optimize the sealing design of products
  • Design customization according to application working conditions, such as assembly requirements, stress resistance requirements, etc...
  • Enhance quality and functionality, by having the ability to predict seal deformation in a variety of modes, thus improving the overall functionality of the sealing system.
  • Establishing GMORS material formula database to facilitate the development and design of seals that meet performance criteria of the actual operating environment.

Based on the results of FEA, we can make the following observations

1. Stress and Strain Distribution:

  • Observation of stress distribution on the seal to determine the location of maximum contact stress and largest deformation, and whether this excessive stress concentration could result in component damage.
  • The geometrical shape of the seal before and after compression was compared.

2. Contact Stress Distribution (Sealing Force):

  • Observation of the overall sealing integrity of the seal after compression.
  • Determination of whether the sealing force can meet the requirements of the working condition.
  • Comparison of the sealing strength before and after compression.

3. Normal Force Distribution (Positive Force):

  • Observe the degree of resistance encountered when the seal is assembled into the housing.
  • Stability during installation. Extrusion and nibbling or rolling of the seal will result in physical damage.
  • The degree of resistance encountered during assembly and disassembly.
