Assessing Truck Ride Quality for Design
This report summarizes a three-year project to characterize and improve the ride quality of the Department of Energy (DOE) tractor/trailer. A high-fidelity computer model was used to simulate the vibrational response in the passenger compartment of the truck due to a common roadway environment. It is the intensity of this response that is indicative of the ride quality of the vehicle. The compu...
متن کاملConsidering Driver Balance Capability in Truck Shifter Design
A person’s ability to perform a task is often limited by their ability to maintain balance. This is particularly true in lateral work performed in seated environments. For a truck driver operating the shift lever of a manual transmission, excessive shift forces can necessitate pulling on the steering wheel with the other hand to maintain balance, creating a potentially unsafe condition. An anal...
متن کاملDesign Considerations for a PEM Fuel Cell Powered Truck APU
In recent years interest has been growing in using fuel cell powered auxiliary power units (APUs) to reduce idling in line-haul trucks. Demonstrations of this technology have been constructed at universities and within industry, each with its own advantages and disadvantages. Invariably, in every design, tradeoffs need to be made and this has resulted in a multitude of different APU solutions t...
متن کاملCombat Readiness Test: Design and Validation in the Iranian Military
Background and Aim: Physical fitness is a major contributor to combat readiness, and current military tests do not measure it appropriately. The purpose of this study was to design a combat readiness test that could reliably and consistently determine the level of physical fitness distinctly required prior to deployment into the battlefield. Methods: The subjects of this study were military per...
