About this file
This data package outlines the technical requirements for modeling and simulating vehicle thermal management systems. It includes data sheets to define parameters such as vehicle propulsion characteristics, mobility specifications, suspension details, and thermal management subsystem requirements. Technical information covered encompasses areas like engine performance maps, transmission components, battery specifications, and heat transfer coefficients. The purpose is to provide a standardized format for communicating vehicle system data to support high-fidelity thermal modeling and analysis simulations.
The federal contract notice announces a Joint Light Tactical Vehicle (JLTV) Family of Vehicles follow-on production opportunity. The Department of the Army Materiel Command will hold an industry day on February 24-25, 2020 at Selfridge Air National Guard Base to provide an overview of requirements for competitively awarding a five-year contract with additional option years. The event will include presentations on acquisition strategy, opportunities for one-on-one discussions, and a static vehicle display. Questions are due by February 19, with responses posted by April 30. Interested parties must submit attendee requests by February 14. The opportunity is at the unclassified level, and the technical data package and first draft RFP will be released in March.

Mobility (2) Reference Drawings
| Reference Instructions for Tire Deflections (on WheeledVehicles sheet) |
| The following data sheets, BW1c, BW1d, BW1e, and BW1f contain information with regard to possible tire deflections which can be slected for operation on different off-road and on-road surfaces. NRMM I contained three possible choices for tire deflection based upon operation on (1) roads, (2) off-road (fine-grained soil) and (3) mud-sand-snow. The user selected one of two operating scenarios during execution of the main module. The tire deflection could either be governed by (1) the surface type (road, off-road, or mud-sand-snow) or (2) be fixed by the user regardless by the surface type upon which the vehicle was operating. |
NRMMII expands these options to accommodate the wide range of tire operating inflation pressures afforded by a Central Tire Inflation Pressure System (CTIS) and permits the vehicle data developer to choose what tire deflection should be used depending upon the surface type. There are eight CTIS surface type scenarios (BW1f) for which the user can designate a tire deflection case. The vehicle data developer identifies how many tire deflection cases, NJPSI, are available for his vehicle. He then identifies the tire deflections, DFLCT(I,JPSI), for each axle assembly (I), and tire deflection case, JPSI, and which tire deflection case, JPSI, applies to each of the eight CTIS scenarios.
The options provided by this approach are: (1) a different tire deflection case for each CTIS operating cas scenario, that is, a total of eight different tire deflection cases. (2) the same tire deflection case applied to several CTIS operating scenarios, (less than eight tire deflection cases. (3) the same deflection case applied to all CTIS operating scenarios, (one tire deflection case).

X value at reference point thus is zero. All trailer values are negative. All Y values are measured from the ground for the tire deflection cases for C-G (sand) and other soils off-road.

| (1) For solid axles, excluding spindle, wheel hub, and wheel/tire assembly |
| (2) If the axle is not a single body, then show its configuration in drawings and provide CG, mass, and inertia information for each major component |
| (3) relative to a point clearly identified in a drawing attached |
| (4) Mass (lbf-sec2/in) = Mass (lbm) / 386.088 |
| (5) Inertia (lbf-in-sec2) = Inertia (lbm-in2) / 386.088 |
| (6) Identify coordinate system used |
| Provide a finite element model for each body that should be considered a compliant structure. |

| For Position sensitive dampers- 1) Provide compiled S function block for black box model AND 2) Fill in "Pos_sens_Damper_Data" datasheet |
| For load sensitive springs- 1) Provide compiled S function block for black box model AND 2) Fill in "Pos_sens_Damper_Data" datasheet |
| S-funciton block should be provided with clear details about input/output channels, units, and polarity |
| (1) Include sufficient data to adequately represent nonlinear characteristics of the curves |
| (2) For linear springs, spring stiffness value would suffice |
| (3) Include sufficient data to adequately represent nonlinear characteristics of the shock curve up to +/- 3 m/s (~120 in/s) |
| (4) Identify shock curve polarity whether extension (rebound) or compression (jounce) is positive |
| (5) Indicate whether the data provided is for individual component or suspension assembly |
| (6) Verify that the data provided is at the component location (NOT at the wheel center) |
| 7) Provide data on jounce bump-stop damping characteristics also if available |

| Notes |
| 1) Data is to be provided from full rebound to full compression |
| 2) Also, provide the compiled S funciton block with clear description of input/output channels, units, and polarity. |
| 3) Spring curves below are required to match the S-block file data (if provided), or risk the use of either data for analysis |
