Abstract

Determining the mass of a vehicle from ground-based passive sensor data is important for many traffic safety requirements. This paper presents a method for calculating the mass of a vehicle using ground-based video and acoustic measurements. By assuming that no energy is lost in the conversion, the mass of a vehicle can be calculated from the rotational energy generated by the vehicle’s engine and the linear acceleration of the vehicle over a period of time. The amount of rotational energy being output by the vehicle’s engine can be calculated from its torque and angular velocity. This model relates remotely observed, engine torque-induced frame twist to engine torque output using the vehicle’s suspension parameters and engine geometry. The angular velocity of the engine is extracted from the acoustic emission of the engine, and the linear acceleration of the vehicle is calculated by remotely observing the position of the vehicle over time. This method combines these three dynamic signals; engine induced-frame twist, engine angular velocity, and the vehicle’s linear acceleration, and three vehicle specific scalar parameters, into an expression that describes the mass of the vehicle. Finally, this method was tested on a semitrailer truck, and the results demonstrate a correlation ofmore »« less

Laser velocimeter measurements in the turbine of an automotive torque converter. Part 2: Unsteady measurements

Journal Article Brun, K ; Flack, R D - Journal of Turbomachinery

The unsteady velocity field found in the turbine of an automotive torque converter was measured using laser velocimetry. Velocities in the inlet, quarter, mild, and exit planes of the turbine were investigated at two significantly different turbine/pump rotational speed ratios: 0.065 and 0.800. A data organization method was developed to visualize the three-dimensional, periodic unsteady velocity field in the rotating frame. For this method, the acquired data are assumed to be periodic at synchronous and blade interaction frequencies. Two shaft encoders were employed to obtain the instantaneous angular position of the torque converter pump and turbine at the instant ofmore »« less

Seismic energy response of multistory steel frames

Thesis/Dissertation Safavi, B

The influence of seismic-input motion parameters and structural parameters on the energy response of a selected structure subject to ground motion was studied. Energy response is defined as the input energy and the energy accumulated and dissipated in the structure. The selected study structure is a 10-story moment-resisting steel frame. The moment-rotation relationship is assumed to be bilinear for the beams and linear for the columns of the structure. The frame is designed for equivalent lateral seismic loads as well as for vertical load. The frame is subject to a variety of simulated base motions consisting of sinusoids and combinationmore »« less
Discrete time blade pitch control for wind turbine torque regulation with digitally simulated random turbulence excitation

Thesis/Dissertation Sharif-Razi, A R

A time domain simulation model that approximates the three-dimensional velocity fluctuations of wind turbulence was developed. This model is used in a discrete time control algorithm to regulate the output torque of a wind turbine by changing the pitch angle of the turbine blade. The wind model provides a velocity field that varies randomly with time and space and gives the proper correlation between spatial locations and velocity components. In addition, the spectral representations approximate those observed from a rotating reference frame. The version of the model described is a time domain simulation. It makes use of a random numbermore »« less

Free (Reactionless) Torque Generation - Or Free Propulsion Concept

Journal Article Djordjev, Bojidar - AIP Conference Proceedings

The basic principle in Newtonian Mechanics is based upon equal and opposite forces. Placing the vectors of velocity, acceleration, force and momentum of interacting objects along a single line satisfies the claim it is a linear or a 1-D concept. Classical Mechanics states that there are two main kinds of motion, linear and angular motion. Similarly placing the vectors of angular velocity, angular acceleration, torque and angular momentum along a line in the case of rotation in fact brings a plane 2-D interaction to the well known 1-D Newtonian concept. This adaptation transforms Classical Mechanics into a 1-D concept asmore »« less
