Development of a vibration measurement device based on a MEMS accelerometer
Onuorah, Chinedum Anthony; Chaychian, Sara; Sun, Yichuang; Siau, Johann (SciTePress, 2017)This paper proposes a portable and low cost vibration detection device. Enhanced vibration calculation, reduction of error and low storage memory are complementary accomplishments of this research. The device consists of ... -
Evaluation of Pavement Roughness and Vehicle Vibrations for Road Surface Profiling
Onuorah, Chinedum Anthony (2018-01-14)The research explores aspects of road surface measurement and monitoring, targeting some of the main challenges in the field, including cost and portability of high-speed inertial profilers. These challenges are due to the ... -
Improving Displacement Measurement for Evaluating Longitudinal Road Profiles
Onuorah, Chinedum Anthony; Hutton-Mckenzie, Angus; Chaychian, Sara; Sun, Yichuang; Siau, Johann (2018-05-01)This paper introduces a half-wavelength peak matching (HWPM) model, which improves the accuracy of vehicle based longitudinal road profilers used in evaluating road unevenness and mega-textures. In this application, the ...
