About this file
This document contains a worksheet for calculating center of gravity and weight distribution for vehicles undergoing wheelbase changes or auxiliary axle installations. The worksheet requires inputting specifications for the original vehicle configuration including wheelbase, weight distribution, and gross axle weight ratings. Fields are then provided to enter new wheelbase dimensions if altered, weight of original and additional axles if installed, and desired axle load for weight proportioning. Calculations are performed to determine the new vehicle's horizontal and vertical center of gravity, front and rear weight percentages, and individual axle loads. Notes indicate the accuracy depends on input data and that a FMVSS 121 analysis may be required for increasing the gross vehicle weight rating.
The related federal contract opportunity is a draft solicitation for light duty vocational trucks with a tentative proposal due date of September 12, 2022. The solicitation is being issued through GSA Federal Acquisition Service for the procurement of various light duty vocational trucks.
