This paper examines a number of ride response measures (Absorbed Power, Vibration Dose Value, Root Mean Quad, and Root Mean Square weighted acceleration), and their relationships. The methodology uses synthesised road surfaces with prescribed spectral properties and pitch plane vehicle dynamics models to predict the response of the vehicle system at various speeds.

"Con Rod Length and Piston Motion in Lotus-Ford Twin Cam Engines"
This report details an investigation into the geometry defining piston dwell, piston displacement, velocity, acceleration and crank moment arm at varying crank angle, as affected by stroke, con rod length and piston pin offset. It aims to provide a rigorous basis on which these affects can be further studied. This report is approx 370k and is in pdf format.
