PLM RFQ Attachment A MBE requirements pdf final.pdf

NASA has identified Model Based Engineering (MBE) as a key Digital Transformation capability to improve quality of designs, reduce risks, improve schedules, and reduce costs.

Consistent with these Agency objectives, the MSFC Engineering Organization requires the capability for a Model Based Engineering (MBE) environment for design, analysis, simulation, and manufacturing. A complement of tightly coupled products and services is required to achieve the desired model associativity and efficiencies provided by an integrated design suite of tools.

MSFC MBE Environment Requirements:

1. The MBE environment shall be designed specifically to manage models in the existing and proposed Engineering application suite with limited custom or third-party integrations

2. The common modeling environment (CME) will be compromised of an integrated set of existing and future repositories, including a Product Lifecycle Management (PLM) tool to manage the interoperable tool set

3. The CME shall provide high-end PLM functions:

a. Manages complex product information throughout lifecycle

b. Provides access to all consumers to the single authoritative model; single source of truth

c. Provides configuration and change management

d. Provides engineering and manufacturing workflows

e. Enables collaboration on data, specifically models

4. Any proposed PLM should be capable of managing the data from existing and proposed Engineering application suite without custom or third-party integrations. The PLM should be able to manage the latest versions of the Engineering application suite as they are released.

5. Any new PLM shall be capable of integrating with our current PLM, ICE Windchill, either directly or via third-party tool.

6. The core tool set shall maximize interoperability/associativity between tools. Specifically, the Mechanical Computer-Aided Design (MCAD), Electrical CAD (ECAD), stress & thermal analysis, Computer-Aided Manufacturing (CAM), Additive Manufacturing (AM), and Operations Simulation models shall all reside in the CME/PLM allowing changes to update automatically across all of those models for a specific design.

7. Initially, the core set shall include a primary CAD, structural & thermal analysis, ECAD, CAM, Additive Manufacturing, and an Operations/Manufacturing simulation tool. In later phases, the tool set should be able to scale to include all other disciplines like systems, fluid dynamics, etc.

8. NASA/MSFC Core tools that we are currently using and are not open to changing: Mentor Graphics ECAD, NX NASTRAN, Femap, Process Simulate Human, and Fibersim. CAD, structural & thermal analysis, CAM, AM, and Operations tools shall be chosen to work with the latest software versions of these tools per the interoperability requirements, without need for custom or third-party integrations.

9. Each individual core tool shall have the following characteristics:

a. High-end/High-performance. Able to handle our complex space applications and environments

b. Accurate/trustworthy results

c. User interface that is evaluated as efficient and intuitive

d. Accepted by the user community

10. Additional CAD tool requirements:

a. Support high-end Model Based Design (MBD) Product Manufacturing Information (PMI) capability, including export to 3D Portable Document Format (PDF)

Product Life-cycle Managment (PLM) Performance Work Statement

b. Support integrated AM and topology optimization tools

c. Export CAD design data into multiple formats including the latest common neutral formats: STandard for the Exchange of Product (STEP), Initial Graphics Exchange Specification (IGES), and Jupiter Tessellation (JT)

11. Additional thermal analysis requirements:

a. The tool shall provide a high-end space thermal capability, including capability to generate on-orbit environments (view factors to space/vehicle). The ability to calculate solar, albedo, nor IR fluxes when in an orbital space environment and provide planetary surface environments.

b. Ability to import Printed Circuit Board design data directly from Mentor Graphics into the analysis tool

c. Can provide 1-d fluid system modeling for simplified fluid modeling. This is integral to most of the tools MSFC uses to model Environmental Control and Life Support Systems and active (pumped) fluid models. The tool shall simulate a pumped fluid loop and the heat transfer to/from thermal hardware. The tool shall also provide a means of determination of pressure drop and mass flow essential to size pumps, valves, etc.

d. Can update model by opening and editing in Excel directly

e. Can use simple conditional logic in fields (no FORTRAN input files or codes needed)

f. Can map individual FEM models to parts at the assembly FEM level.

g. Can map to multiple identical parts at once with no need to reposition due to being linked to the CAD

h. Position changes in general are maintained at the design level and Finite Element Model

(FEM) are repositioned automatically; benign to moderate changes in geometry can be updated from the CAD effortlessly and maintain thermal couplings with an automatically updated mesh

i. Has an effective command finder tool

j. Can show multiple views of varying results with the option of synchronizing viewports

k. Open to adding and modifying features based on feedback (e.g. can add optical property library)

12. Additional structural analysis requirements:

a. Trusted core solver

b. Allow design analysis solver flexibility options embedded in the pre/post processing tool for use by preference in the various engineering departments at MSFC: NASTRAN, ANSYS, or Abaqus

13. Additional CAM requirements:

a. The CAM model shall be associative and created directly from the CAD model

b. The Computer Numerical Control (CNC) toolpath shall be created directly from the CAM model

c. The CNC programming language, G-Code, file shall be generated directly from the CAM toolpath using an output post processor

14. Additional Additive Manufacturing (AM) requirements:

a. The AM tool shall provide capability for additive design, advanced lattice design, topology optimization, and additive simulation

b. The AM tool shall have direct integration features, including toolpath generation, for our existing manufacturing machines, including our specific ConceptLaserRP and EOSPrint machines

c. The AM tool shall have a direct integration with Materialise Magics AM solid object manipulation software; allows for use of existing Magics models

d. Specific features required are effective overhang, volume analysis, and channel diameter analysis tools

15. Additional Operations/Manufacturing Simulation requirements
