Engineering Calculations

Since our foundation in 2006, we have consolidated our expertise in mechanical structures, solving diverse problems analytically, numerically or combining both skills, performing in Metalworking, Aerospace, Nuclear and Oil&Gas industries.

FINITE-ELEMENT ANALYSIS

Development of consistent and reliable finite-element models for assessment of mechanical systems, design optimization, product development, and machine elements sizing.

THREADS ANALYSIS

Standardized approach for performance assessment, sizing or optimization of threaded connections, with regard to geometry, tolerances, and load cases. We have performed 2500+ analyses of steel threaded connections, from 3” to 36”.

Types of analyses include:

STRUCTURAL ANALYSIS

Sizing and verification of complex mechanical systems or single parts, subjected to static or dynamic loading, within linear and non-linear problems.

  • Static analysis (linear or with material or geometric nonlinearities).
  • Dynamic analysis (modes, vibrations).
  • Seismic analysis (seismic loadings on vessels and control rods).
THERMAL ANALYSIS

Assessment of mechanical systems involving temperature changes. Parts or mechanisms interactions under differential temperature variations. Heat dissipation, conduction and convection.

ROUTINES PROGRAMMING WITH PHYTON FOR ABAQUS

Development of scripts for modelling: mesh generation, components interaction definitions, properties and materials assignment, loads and boundary conditions definition. User-defined specific functions. Development of tools for post-processing and results visualization.

MACHINE ELEMENTS VERIFICATION

Sizing and verification of shafts, bushings, bearings, wheels, gears, etc. Stress Analysis. Variable and dynamic loads. Bolted and welded connections. Couplings. Tribology. Seals and packings. Springs. Cylindrical and helical gears, worm drive, rack and pinion. Machine vibration isolation.

PARAMETRIC ANALYSIS AND DESIGN

Evaluation of different scenarios for mechanical systems or mechanisms defined by variations of certain values (parameters) within a context of fixed variables.

IMPACT ANALYSIS

Analysis of non-linear responses in mechanisms or parts under impact loading (sudden acceleration variations).

DESIGN AND VERIFICATION OF CRANES AND HOISTING APPLIANCES
