Material tensile loading is primarily done by clamping two ends of a specimen and stretching it using a linear actuator. NRL has instead developed a multi-axis loading robotic system that can apply loads to the specimen in any direction, at any torque, and at high frequencies. This technology is used for the application of cyclic fatigue loading of sample specimens in a high speed, arbitrarily complex, and multiaxial frequency manner on order to simulate real world loading scenarios of said specimens. This is expected to lead to more optimized design of mechanical and airframe parts while also helping future customers to prevent catastrophic system or platform failures. NRL seeks to 1) Commission the most recent iteration of the multi-axial tensile loader, codename “66.7”. This robotic system is mostly constructed; however the final hardware pieces and system design require dedicated engineering expertise. NRL also seeks to 2) prepare 66.7 for transfer to commercial entities. This includes formalizing blueprints, system hardware manuals, assembly instructions, etc. NRL wants to turn the 66.7 into something that can be ordered at a commercial/industrial level. Section 2 Objective/ Scope‑. For the commissioning of the 66.7, the scope centers around design and provision of several pieces of hardware. Specifically, these cover hydraulic grips, weldments, spacers, hydraulic controls, mounting plates, safety shield, wheeled cart, and other safety and quality-of-life design considerations. The contractor should be proficient in machining large parts (weldments), hydraulic systems, and precision machining (encoder mounts). The contractor will be designing many of these systems in addition to providing the hardware. Electronics control expertise is not required but desired for integration of hydraulic electronic controls. At the end of the contract performance, the robot is expected to be able to grip vertical specimens of various given lengths utilizing hydraulic grips. Once gripped, the existing hydraulic hexapod structure will be able to perform 3D displacement tests and 3D torsion (bending) tests on the specimen.  In short, the robot is to be used for bending metal specimens to extract material properties. Said robot requires upgraded safety measures including a safety shielding enclosure and hydraulic lashing. Software and electronic controls are provided by NRL, this contract is strictly for hardware acquisition, robotic assembly at NRL, and system documentation. For the commercialization of the 66.7, NRL seeks contractor expertise in compartmentalizing the 66.7 subsystems, and recommendations for system design simplification. It is understood that the 66.7 system is a custom construction for a laboratory setting. As such, many of the subcomponents could potentially be simplified or compartmentalized for production by different commercial entities, streamlining future system construction. The goal is to have instructions for constructing a system that a non-NRL entity can construct at the request of a potential client. Section 3 Applicable Documents.
