Topic Num:  SOCOM07-001 (SOCOM)
Title:  Advanced Lightweight Vehicle Components and Materials
Research & Technical Areas:  Ground/Sea Vehicles, Materials/Processes

Acquisition Program:  Family of Special Operations Vehicles
  Objective:  Design, develop, fabricate and test structural driveline and chassis components to decrease the fixed mass of the Expanded Capacity Vehicle High-Mobility, Multi-Purpose Wheeled Vehicle (HMMWV) and increase the effective payload.
  Description:  Ground mobility forces are conducting increased mounted operations from armored HMMWV and modified HMMWV’s. As additional armor and equipment continues to be added to the system, the performance of the existing power train, suspension, steering and chassis components are not sufficient. Alternate programs are focusing on an improved power train; therefore this effort will provide vehicle integration of improved components. Lightweight, high strength and cost effective solutions are required. Full mission payloads are currently yielding Gross Vehicle Weights (GVW) which are up to 2,400lbs in excess of rated GVW. This causes multiple vehicle issues ranging from high stress and wear to instability and undesirable center of masses.

  PHASE I: Develop a parametric approach to component identification for defined weighting functions of mass reduction, durability, cost and integration of applicable components. This will identify and define the ranking of component severity. Based upon this matrix, develop conceptual designs for the ranked components. Conduct analysis and simulation on the designs for down selection for components for Phase II. This approach will highlight strengths and weaknesses with designs and will consider overall weight reduction, component and material cost, component complexity, strength, component life, and overall practicality of increasing the HMMWV’s GVW. This effort will focus on modeling and simulation yielding cost effective solutions that suit the increased GVW directive while attempting to integrate as many solutions as possible to suit ground mobility requirements. Vendors shall submit a business plan for the commercialization of the technology developed under this topic. The Small Business Administration's web site www.sba.gov provides guidance, examples as well as contact information for assistance. All firms shall include as part of the Phase I proposal transportation costs to travel to Tampa, Florida for two separate meetings. The first travel requirement shall be the Phase I kick-off meeting and the second travel requirement shall be for the Phase I out brief. The meetings shall take less than four hours and at least the Principal Investigator is required to attend both meetings. Notwithstanding the requirement for the Principal Investigator to attend both meetings, any other individual needed to discuss all aspects of the firm's approach to address the Small Business Innovation Research topic shall also attend the meetings.
  PHASE II: Further refine and develop models generated in Phase I and a create Level 2 Technical Data Package. Develop, demonstrate and provide complete prototype and integration of components and systems for model validation, reliability testing and evaluation. Deliverables may be subject to several thousand miles of testing in realistic HMMWV mission profiles including courses and terrain that represent Aberdeen and Yuma Proving Grounds, Middle East, Afghanistan, embedded rock, and degraded pavement.

  PHASE III: These increased component capabilities could be used in other military and civilian applications for increased payload and GVW capabilities.

Questions and Answers:
Q: 1. What is the maximum payload of the current HMMWV?

2. What are the performance results of the current HMMWV at maximum payload?

3. What are the weights of the major subsystems in the current HMMWV?

4. What are the objectives of the improved powertrain projects?
A: 1. Max rated GVW is 12,100 lbs. Payload varies depending on base configuration. 2000lbs is approximate cargo capacity once armor is applied to the vehicle. Crew members and gear are considered part of the cargo. Current field data indicates some units are exceeding rated GVW by more than 2500 additional lbs.

2. Test data is not being made available at this time.

3. Technical data is not being made available prior to contract awards.

4. Other projects, i.e. improved powertrain, all share a common goal of overcoming the system challenges related to increased cargo requirements. The overall program goals are to restore vehicle performance numbers to those realized of the base vehicle when properly loaded.

Q: Is it possible to access on line a description of the specific components in question (e.g. geomentric configuration and material properties), and their current structural and mechanical design criteria?
A: Technical data is not available in the public domain.
Q: Our company is considering pursuing this topic but we only have access to civilian H1 systems. Would we be provided with a military HMMVW to disassemble and evaluate parts for possible weight reduction gains?
A: No GFE or GFI will be made available until SOW / Contract Awards.
Q: In addition to the above, would we have access to an armored hummer so that we can measure changes to center of gravity, load on axles and ensure minimal performance changes due to changes in load distribution?
A: This information would be provided at a SOW / Contract Award, not prior. The Government already has this data, and thus would not be providing a HMMWV, rather information only.
