CDC - Mining Contract - Dump Truck Vibrations and …
Liming · Huge mining shovels load enormous haul trucks with 100-ton passes. High-impact shovel loading operations (HISLO) can involve severe truck vibrations that expose operators to whole body vibration (WBV). The operator's lower torso, lower back, legs, feet, and hands are exposed to these WBV levels. The operator seat, lumbar, and cervical regions

"Dynamic impact of ageing dump truck suspension …
"Surface mining operations typically deploy large shovels, with 100+ tons per pass capacity, to load dump trucks in a phenomenon described as high-impact shovel loading operations (HISLO). The HISLO phenomenon causes excessive shock and vibrations in the dump truck assembly resulting in whole body vibration (WBV) exposures to operators. The truck suspension system …

Virtual Prototype Simulation of Truck Vibrations in High
Liming · production operations has resulted in High-Impact Shovel Loading . Operations (HISLO). In extreme cases, shovels load large dump trucks with 100ton (or more) passes generating high-impact forces under gravity. HISLO generates high-frequency shockwaves that cause severe truck vibrations exposing operators to Whole Body Vibrations (WBV).

What Are the Causes of Vibration on Trucks? | It Still Runs
Vibrations in your truck can be difficult to diagnose because there are a variety of things that can cause them to occur, including outside factors, such as rough roads. However, once you are certain it is your truck vibrating and that the vibration is more severe than the slight vibrations often caused by a running engine, look for several

Whole-body vibration in underground load-haul-dump
Liming · Abstract Whole-body vibrations (WBV) were measured at the seatpan of load-haul-dump (LHD) vehicles of 3.5-, 5-, 6- and 8-yard capacity at two underground mines. Twenty-two sets of measurements were made involving 11 vehicles, 8 operators and 4 work locations. In each set frequency-weighted rms and peak accelerations were measured in the x, y and z …

Operator health risk evaluation of off-highway dump truck
Kefid · Discrete element method was utilized to accurately estimate the impacting force on the truck body. Based on the ISO 2631-5 criteria, the S ed is about 0.56 MPa in both models, which means that the dump operators have a high probability of adverse health effects over long-term exposure to these vibrations.
