Dynamic stability of forklift trucks in cornering situations: parametrical analysis using a driving simulator

Research Using Virtual Reality: Mobile Machinery Safety in the 21st Century

“…One strategy will examine the performance of the physics-based simulation by evaluated similarity of the chassis accelerations in the laboratory tests compared to field data; this is similar to the approach performed by other researchers [60,94]. For this purpose we have created a virtual environment that includes a test track with known vibration characteristics [95].…”

“…Many laboratory studies have used Stewart/Gough motion platforms to control multi-axis vibration exposures [54][55][56][57][58][59]. As well, there has been a trend to incorporate virtual reality (VR) environments to evaluate the visual field and work environment for research [60,61] and training [62][63][64]. However, these initiatives have emphasized the fidelity of the visual environment, not the vibration environment; for example, many initiatives have used fixed-base simulators and therefore have no whole-body vibration [65][66][67].…”

“…If motion platforms have been incorporated, their implementation has focused on the haptic elements of the vibration environment (to increase the amount of presence) [68][69][70] rather than the fidelity of the whole-body vibration exposure. Virtual reality-based modeling studies have been particularly useful for evaluating line-of-sight for different vehicle configurations [71,72], for predicting line-of-sight for specific worker populations, such as child farm tractor operators [73], or for evaluating handling performance [60] and hazard responses [74] which would be dangerous to investigate in the real world.…”

Research on Modeling and Active Steering Control Algorithm for Electric Forklift Steer-by-Wire System

“…Steering motor drive signal can be worked out. Besides, the main controller (ECU) controls the road feeling motor to realize road feeling simulat ion of mechanical steering system [7][8][9][10][11].…”

“…Remove mechanical linkage between the steering handle and front wheels is the main characteristic of SBW system, so the various limitations of conventional mechanical steering system are co mpletely non-existent [8,9,11,12]. Therefore, the angular transmission characteristics of forklift can be easily designed, and the force transmission characteristics of the forklift can be designed according to the need of design, which brings inf inite space to the design of the electric forklift steering characteristics.…”
