“…The result of these studies showed that occupational exposure to WBV had a relationship with LBP, degenerative changes in the spine including lumbar intervertebral disc disorder, musculoskeletal pain, psychological stress, and sciatic pain (Finset et al, 2004; Seidel 2005; Seidel et al, 2008; Zhang et al, 2019; Rahmatalla and Liu 2012). Thus, in order to control these disorders, the vibration magnitude or its exposure should be reduced, as emphasized by many researchers (Pavlovic-Veselinovic et al, 2016; Ekoru et al, 2016; Chaudhary et al, 2015; Finset et al, 2004).…”

Whole-body vibration (WBV) is a recognized health hazard that primarily affects the musculoskeletal system of human beings. Although research works on WBV are documented, for the past few decades or so, researchers are still attempting to explore the role of contributing factors of WBV for the causation of musculoskeletal disorders (MSDs). Therefore, this paper synthesizes up-to-date knowledge on WBV with respect to measurement methods, critical vibration magnitudes, contributing factors, and effects on human health. The present review is based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes) that includes 112 studies on WBV exposure and its contributing factors. It also summarizes the contributing factors of MSDs that include personal factors, environmental factors, machine-related factors, and WBV exposure of the heavy vehicles and equipment operators across various industries. Most of the studies reported lower back pain as the most common MSDs experienced by the vehicle operators exposed to WBV, followed by upper back pain. However, it is apparent from the prevailing literature that musculoskeletal health risks do not result from exposure to WBV alone. The role of multivariate contributing factors should also be considered, analyzed, assessed, and understood to establish correlations between these factors with the development of MSDs. In addition to the measurement and assessment of WBV as per the ISO guidelines to evaluate the potential and likely health risks faced by the heavy equipment operators, researchers should also focus on studying various impacts of WBV, and understanding the role of its contributing factors on human health using advanced machine learning tools.

A simplified analytical model with transformation coefficients of X-type seat system with an integrated spring damper for control strategies development is proposed on the basis of a kinetodynamic model. Firstly, based on a commercial seat of trucks, the relationship between the suspension support force and the spring force was created by using virtual work principle. e analytical formulae of the equivalent stiffness K e and the stiffness transformation coefficient ρ k were deduced. Based on the principle of conservation of energy, the analytical formulae of the equivalent damping coefficient C e and the damping transformation coefficient ρ c were deduced. en, the motion equation of the simplified model was created. Secondly, the nonlinear dynamic equation of a complex seat model including the kinematic characteristics was established. irdly, the road test was conducted using a heavy truck to collect the seat vibration signals. Finally, the simplified model was validated by the tested data and compared with the complex model. e results show that the accuracy of the simplified model is acceptable. Moreover, the influence laws of kinematic parameters on ρ k and ρ c were revealed. e proposed simplified model provides an accurate and efficient tool for designing controllable seat suspension system that minimizes a necessary tuning process.
