This paper presents a comparative study of conventional Experimental Modal Analysis (EMA) and output-only Operational Modal Analysis (OMA) techniques for estimating the modal parameters of a moderately damped truck chassis. The OMA, without its need to measure input forces, would serve as a convenient methodology to test vehicle structures when response data alone is available. Data has been ac...

Our long-term goal is one of designing land-based vehicles to provide enhanced uneventerrain locomotion capabilities. In this paper, we examine and evaluate candidate articulated leg-wheel subsystem designs for use in such vehicle systems. The leg-wheel subsystem designs under consideration consist of disk wheels attached to the chassis through an articulated linkage containing multiple lower-p...

The state of a non-relativistic gravitational dynamical system is known at any time t if the dynamical rule, i.e. Newton’s equations of motion, can be solved; this requires specification of the gravitational potential. The evolution of a bunch of phase space coordinates w is deterministic, though generally non-linear. We discuss the novel Bayesian non-parametric algorithm CHASSIS that gives pha...

The purpose of the work is import substitution traction electric drives as part project to create in Chuvash Republic a serial production family front loaders with hybrid drive.
 
 For most transport motors, operation high-torque motor mode not main operating mode, since vehicle acceleration carried out short time overcoming low-efficiency low-speed modes. A distinctive feature for ch...

The European Commission is examining test procedures to ensure that light-duty vehicle emissions are well controlled both in real use and over the legislative test cycle. At the same time, the UN Working Party on Pollution and Energy (GRPE) has developed a Worldwide harmonised Light vehicles Test Procedure (WLTP) that is expected to be used for Type Approval in the EU in the future. To identify...
