Client / Market
- Manufacturers of machine tools requiring high stiffness structure
- Manufacturers of high-speed, high-precision motion stages for semiconductor or
flat-panel display applications
Necessity of this Technology
- The CAE structural analysis is a widely used technique to evaluate the designs of
mechanical systems. However, evaluating the key performances of a complicated
mechanical motion system is too complicated for mechanical designers in SMEs.
- To secure reliability of the structural analysis result, connecting elements such
as LM blocks, ball screws, servo motors, and encoders should be modeled with
appropriate level of details and accuracy; which requires extensive know-hows and
- It is necessary to improve the availability of the structural analysis technology
by eliminating complex and labor intensive tasks including connecting element
creation and 3D geometry simplification.
- Can evaluate the key performances of an entire mechanical motion system, not a
single unit or a part.
- Equipped with know-hows and empirical data to realistically model mechanical
connecting elements including LM blocks, ball screws, servo motors, and encoders.
- Manual work necessary for CAE structural analysis is minimized with automation
Excellence of Technology
- A mechanical designer without expertise on CAE analysis can build the analysis
model of a complicated mechanical motion system with minimum user input thanks
to automation of complex processes of modeling connecting elements, geometry
simplification and assembly of finite element models.
- Once the primary structural analysis model is built, the same type of analysis can
be repeated in multiple positions automatically to evaluate the position dependent
- The basic structural analysis results are automatically processed into more
insightful performance indices, such as structural loop stiffness, gravity induced
machine accuracy, and motion performances.
