S.A.Robotics

Structural, Dynamic, Kinematic, FEA, Seismic Analysis Services

S.A.Robotics provides a suite of engineering analysis. These analyses cover a complete range of disciplines including mechanical, electrical, electronics, civil, structural, and controls. They include the following:

• Structural analysis
• Seismic analysis
• Modal analysis
• Kinematic analysis
• Safety analysis
• Fluid Flow Analysis
• Electrical Analysis

In addition to analyses performed as part of design projects, S.A.Robotics also provides these capabilities on a consulting basis. Our project experience includes:

• large concrete structures
• large steel structures
• long reach carbon fiber structures
• hydraulic fluid systems
• mechanical power transmission systems
• detailed mechanism
• ventilation and cooling systems
• piping and process flow
• materials in radiation environments
• nuclear safety assessments
• circuit board design
• precision motion control w/ inverse kinematics

Analysis are preformed with a combination of hand calculations and computer models analyzed with FEA. The analysis packages used in house are:

• Pro/Mechanica
• Structural Analysis Program (SAP)
• Matlab
• Simulink

The following are examples of analyses S.A.Robotics has performed for past projects:

Seismic, wind, structural analysis for Bechtel Reactor Vessel Head Replacement Platform:

This analysis included complete modeling of large structural steel towers. These towers were then analyzed for comprehensive load cases including combinations of static seismic, wind loading, dead load, and live load. This analysis was performed based on the UBC 97 code and the AISC code for stress limits in beams and welds.

Full dynamic seismic analysis of concrete reactor for UKAEA Windscale Piles Reactors:

This analysis investigated the impact on the existing reactor structure on removing the pile cap. This was done with a full dynamic spectrum response based on site approved seismic forcing functions and the natural frequency of the structure. The output of this analysis was compared to ACI 318-02 for acceptable loading based on known thickness, strength, and reinforcement of the concrete. The final analysis package was reviewed and approved by the engineering firm Sanderson Watts Associates of Great Britain.

Structural Analysis of Vapor Dome Dismantlement at Yankee Rowe:

This analysis involved the construction of a large, detailed model of a vapor dome containment structure. The analysis compared the relative merits of various dismantlement approaches based on how the structure would be loaded and stressed when sections were removed. This analysis allowed the removal to be done safely and without incident.
