Systems Engineering M939 Add on Armor Kit Hand sketched on a drafting board and converted into Computer Aided Design (CAD). Kit was designed and first prototype built in two months. 3,000 kits produced for OIF/OEF 7/23/2018 DISTRIBUTION STATEMENT A. Approved for public release; distribution unlimited.

Systems Engineering Top Down Design for Optimization Typical bottom up approach Top down design used to initially used to develop mine reduce weight and size and blast cab. maintain mine blast performance. 7/23/2018 DISTRIBUTION STATEMENT A. Approved for public release; distribution unlimited.

Systems Engineering Traditional/Typical Top Down Design Typical Approach of Top Down Modeling Using One Skeleton per Assembly 7/23/2018 DISTRIBUTION STATEMENT A. Approved for public release; distribution unlimited.

Systems Engineering Alternative Top Down Design for Larger Assemblies For more complex models, the idea is to make skeleton model assemblies to reduce the amount of features in each skeleton and keep the models clean 7/23/2018 DISTRIBUTION STATEMENT A.

Systems Engineering TARDEC Amphibious Combat Vehicle (ACV) Skeleton Model This is the top skeleton model for the TARDEC Amphibious Combat Vehicle Hull Survivability Demonstrator. This skeleton will drive all the individual parts shape. This skeleton controls thousands of features. 7/23/2018 DISTRIBUTION STATEMENT A. Approved for public release; distribution unlimited.

Systems Engineering Concept Skeleton Model (Upper Hull) This is the upper hull skeleton that is simplistic geometry that can be easily modified. This is a model that can be made by Advanced Concepts and transitioned to Detailed Design. 7/23/2018 DISTRIBUTION STATEMENT A. Approved for public release; distribution unlimited.

Systems Engineering Concept Skeleton Model Edge Prep This is the upper hull skeleton that has added sketches and sweeps to cut the parts. If done correctly, the conceptual model shown in the previous slide can change shape and the edge preparation will update. Sketches for sweeping Sweep in the Skeleton or extruding the edge Model cuts 7/23/2018 DISTRIBUTION STATEMENT A. Approved for public release; distribution unlimited.

Systems Engineering Transition from Concept Design to Detailed Design Part with copied geometry or published geometry from the skeleton These sketches are used to create the cut for the J-Weld between the Parts and Finished Joint Geometry Mechanical Lock with J-Weld Edge Prep and Mechanical Lock 7/23/2018 DISTRIBUTION STATEMENT A.
