In most structural pavement design methods, strains and stresses in the layers are calculated with multi-layer programs based on the Burmister model using the linear elastic theory. Burmister defined loads as a constant pressure applied on a circular surfa ...
This paper presents a method for wheel-ground contact angle measurement and a traction control strategy minimizing slip in rough terrain. The slip minimization algorithm has been tested and compared with a standard speed control in simulation, which allows ...
Selective Ga + ion implantation and miring by focused ion beam exposure and subsequent wet chemical etching is used to fabricate micro/nanomechanical elements in Si. Freestanding elements with a ~ 30 nm membrane thickness are made by controlled selective u ...
Pavement rutting not only decreases the road service life but also creates a danger for the security of road users. In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. It is well known that the in ...
The aim of the present paper is to extend the well-known complex torque coefficient method usually used for synchronous machine rotor oscillations, to a slip energy recovery induction motor drive. To illustrate the effectiveness of the proposed extension, ...
Robotic ground vehicles are systems that use gravity and contact forces with the ground to perform motion. In this paper we will focus on n-wheeled vehicles able to perform motion with all the wheels maintaining contact at the same time. The main goal of t ...
This paper is concerned with the calibration and validation of a finite-element model of dry sliding wear in metals. The model is formulated within a Lagrangian framework capable of accounting for large plastic deformations and history-dependent material b ...
An innovative technology for the realization of key elements of a microfabricated reduction unit is presented. In view of integrating the functions of gear, pinion and axle into one element, multilevel metal electroplating in a negative dry film resist mou ...
