Computer-aided engineering simulation


Company’s advantagesPLM Ural Engineering center offers computer-aided engineering simulation services to enterprises where it is necessary to :

  • Reduce the number of prototypes and physical tests
  • Investigate more prospective product designs to choose the best one
  • Evaluate the existing technology
  • Define defects’ reasons and find the ways of its correction
  • Decrease metal consumption
  • Accelerate the development of a new technology

Modern CAE systems and deep knowledge help PLM Ural specialists to evaluate accurately on the base of a computer prototype the product behavior at real operating conditions.

The results:

  • Development cost reduction
  • Time-to-market acceleration
  • Product quality increase

Engineering simulation – manufacturing-dependent design performance evaluation

We have the technical capability to run coupled analysis of the following manufacturing processes:

  • stamping – welding;
  • forging – heat treatment;
  • casting- heat treatment, etc.

After manufacturing processes simulation strength, tightness analysis, accounting real product characteristics, can be performed.

This approach enables an engineer to evaluate real product performance and durability.
