Combined optimisation of design and power management of the hydraulic hybrid propulsion system for the 6 × 6 medium truck

Abstract: Hybrid propulsion systems are one of the critical technologies on the roadmap to future ultra-efficient trucks. While there is a significant body of work related to hybrid passenger cars and light ...

Dynamic modelling and stability analysis of articulated frame steer vehicles

Abstract: The stability analysis of articulated frame steer vehicle models is presented. To reveal the relationship between the 'oversteer' and 'jack-knife' motion modes based on a 2 degree of freedom (DOF) and 3 DOF vehicle models, respectively, the results derived from these models are investigated and compared. To identify the effects of design variables on the lateral stability of the vehicle, a more realistic model with a hydraulic rotary valve and dynamic tyre models is generated on the basis of the 3 DOF model and the results derived from these models are examined and compared. Similar to traditional articulated vehicles, the jack-knife and 'snaking' modes were identified from practical operations of the articulated frame steer vehicles. Results demonstrate that, with the decrease of the angular spring (representing the hydraulic cylinder between the front and rear sections of the vehicle) stiffness coefficient, the oversteer mode evolves into the jack-knife mode. Compared with the static tyre model, the effects of dynamic transient lateral tyre force degrades the stability of the vehicle over the lower speed range. Results also illustrate that, with the fluid leakage either in the rotary valve or in the hydraulic cylinder, the stability of the oversteer mode dominated motion degrades. On the contrary, in the case of snaking mode dominated motion, the introduction of the fluid leakage will improve the stability of the vehicles.

On the use of bridge weigh-in-motion for overweight truck enforcement

Abstract: Bridge weigh-in-motion (B-WIM) is a method by which the axle weights of a vehicle travelling at full highway speed can be determined using a bridge instrumented with sensors. This paper looks at the history of B-WIM, beginning with early work on weigh-in-motion (WIM) technologies in the 1960s leading to its invention by Fred Moses and George Goble in the USA in the mid 1970s. Research initiatives in Australia and Europe have focused on improving B-WIM accuracy. The moving force identification (MFI) method models the dynamic fluctuation of axle forces on the bridge and holds particular promise. B-WIM accuracy depends on bridge site conditions as well as the particular data processing algorithm. The accuracy classifications of several B-WIM installations reported in the literature are summarised in this paper. Current accuracy levels are sufficient for selecting vehicles to be weighed using static scales, but insufficient for direct enforcement. Copyright © 2014 Inderscience Enterprises Ltd.

Simulation-based optimal design of heavy trucks by model-based decomposition: an extensive analytical target cascading case study

Abstract: We present the findings of an extensive case study for the decomposed, simulation-based, optimal design of an advanced technology heavy truck by means of analytical target cascading. The use of a series hybrid-electric propulsion system, in-hub motors, and variable height suspensions is considered with the intention of improving both commercial and military design attributes according to a dual-use philosophy. Emphasis is given to fuel economy, ride, and mobility characteristics. The latter are predicted by appropriately developed analytical and simulation models. This article builds on previous work and focuses on recent efforts to refine the applied methodologies and draw final conclusions.

Rollover dynamics of road vehicles: Literature survey

Abstract: This paper presents a review of literature pertaining to vehicular rollover. It is by no means a complete review of all rollover literature available, but covers many of the most frequently cited papers and those that the author believes make a substantial contribution to the field of vehicle dynamics and rollover in particular. This review is limited to papers covering rollover of road vehicles, such as passenger cars, utility vehicles and heavy commercial trucks - both articulated and non-articulated, i.e. the review excludes papers regarding off-road vehicles. In addition, this review focuses mainly on cases of manoeuvre induced rollover such as rollover in cornering, lane-change manoeuvres, etc., though rollover by tripping is discussed to a certain degree. It begins with a general introduction to the rollover phenomenon that may be applied to both articulated and non-articulated vehicles. Non-articulated vehicles are then examined in more detail and a review of some research into stability metrics and the prediction of rollover for these vehicles is presented. Likewise, the stability metrics and prediction of rollover for articulated heavy trucks carrying rigid and liquid cargo is reviewed along with work into active suspensions, braking control and rollover warning devices.
