Validation of a Single Unit Truck Model for Roadside Hardware Impacts
نویسندگان
چکیده
The objective of this research is to validate the Finite Element (FE) model of a Ford F800 Single Unit Truck (SUT). The FE Model of the SUT was developed at the FHWA/NHTSA National Crash Analysis Center (NCAC) at the George Washington University. The SUT model has been used by several transportation safety researchers to evaluate and improve roadside safety hardware. In this study, the characteristics of the SUT model were investigated and several modifications were incorporated in the model to accurately simulate its interaction with roadside safety hardware. A full-scale crash test of the Ford F800 SUT impacting an F-shape Portable Concrete Barrier (PCB) was conducted at The Federal Highway Administration’s (FHWA) Federal Outdoor Impact Laboratory (FOIL) and used in the validation. The response of any vehicle impacting a PCB is primarily governed by the mass and suspension characteristics of the vehicle. Detailed methods for modeling the truck’s suspension components are discussed. The comparison between the FE Model and the crash test in terms of overall impact kinematics, component failure modes, velocity and acceleration at various locations of the vehicle are presented.

The primary purpose of longitudinal safety barriers, such as cable barriers, is to contain and/or redirect errant vehicles that depart the roadway, hence keeping them from entering opposing travel lanes or encountering terrain features and roadside objects that may cause severe impacts. In this study, a detailed finite element model of a three-strand cable barrier was developed and validated ag...
متن کاملStudy of Vibration Specifications of a Three-axle Truck Using Lagrange Method
In this research, Ride quality of a three-axle truck is investigated to understand its vibration specifications and influence of it on special load. The truck is Benz 2624, and the load is rather sensitive to vibrations. The system is considered for an off-road duty. Hence, the vehicle is modeled as a nineteen-degree of freedom system and its equations of motion are derived by employing Lagrang...
متن کاملDevelopment of a Motorcycle FE Model for Simulating Impacts into Roadside Safety Barriers
Recent studies have identified roadside safety barriers as a cause of severe injuries and fatalities for motorcyclists. Roadside safety barrier have traditionally been designed with limited consideration for motorcyclist safety since the primary focus was on the safety of occupants of enclosed vehicles. Computer simulations of full-scale crashes between motorcyclists and road barriers would pro...
متن کاملFinite element model and validation of a surrogate crash test vehicle for impacts with roadside objects
Highway and roadside safety features are crash tested for compliance with certain safety criteria. US Federal Highway Administration (FHWA) uses a surrogate reusable test vehicle, Bogie, to conduct crash tests of roadside safety features. Bogie is intended to replace an impacting vehicle in order to reduce the cost of the test. Bogie can be configured with different crushable impact noses repre...
