“…An accurate determination of the actual values of human parameters is impossible in many cases. Therefore, we can say that the human models found in the literature are described by approximate parameters, as a large discrepancy among them is found [12][13][14][15][16][17].…”

“…The wide range of values found in literature (e.g. [4,10,[12][13][14][15][16][17][45][46][47][48][49][50]) has been taken into account in the process of parameter identification for models representing drivers with different personal features (detailed description of this process can be found in Gagorowski [33]). The parameters of soft tissues for the two models representing two different drivers is shown in Tables 3-5 (see Table 3: stiffness of spinal muscles and ligaments /k 9 -k 16 /; discs, /k 1 -k 8 /; Table 4: damping of intervertebral discs, /c 1 -c 8 /; Table 5: stiffness of body muscles /k 17 -k 27 /; Table 5: damping of body muscles /c 17 -c 27 /).…”

“…The discrete models treat the spine as a layered structure of rigid elements, representing the vertebral bodies, and deformable elements (springs and dampers) representing the intervertebral discs (e.g. Qassem et al [15], Yoshimura et al [7]). The continuum models treat the spine as a homogeneous rod or beam (e.g.…”

This paper presents an original approach to the problem of controlling a magnetorheological suspension of a driver's seat for optimal reduction of whole-body vibration. The concept consists in taking into consideration the individual personal features (biomechanical parameters) of the driver in the control process of a MR damper by using human generated signals. The proposed algorithm enables the adaptation of the suspension for an individual driver and specific road conditions. The actual research has focused on numerical simulations with a complex model of the human-seat-vehicle system. The human model representing a specific driver has been described by several biomechanical parameters such as masses of body structures, moments of inertia, and stiffness and damping of the spine, intervertebral discs, spinal muscles and ligaments.

“…As early as in 1974, M. Robert and others built an six degrees of freedom nonlinear vibration model of human body [10] . In 1994, W. Qassem put forward a description on human body vertical vibration and horizontal vibration as an 11 degrees of freedom vibration model [11] . In 1994, Magnusson et al created some recommendations on how to design a driver's ·2· cab to reduce the exposure of whole body vibration and other risk factors having a negative effect on the health [12] .…”

“…Some of the research concentrated on human's perception [3,4,5] , while others emphasized on the sitting posture [6,9] , and many different human body vibration models were proposed and human whole body vibration test conducted [11][12][13][14][15][16][17][18] . With the rapid development of computational power, simulation software and VR (Virtual Reality) technology, it is possible to integrate all the simulation and modelling aspects together, backed up with a limited number of human whole body vibration test and questionnaire results as validation, to provide a simulation method for rapidly evaluating the sitting posture body comfort of human-vehicle systems.…”

Most of the previous studies on the vibration ride comfort of the human-vehicle system were focused only on one or two aspects of the investigation. This paper proposed a hybrid approach which integrates all kinds of investigation methods in real environment and virtual environment. The real experimental environment includes the WBV (whole body vibration) test, questionnaires for human subjective sensation and motion capture. The virtual experimental environment includes the theoretical calculation on simplified 5-DOF human body vibration model, the vibration simulation and analysis within ADAMS/ Vibration TM module, and the digital human biomechanics and occupational health analysis in Jack software. While the real experimental environment provided realistic and accurate test results, it also serves as core and validation for the virtual experimental environment. The virtual experimental environment takes full advantages of current available vibration simulation and digital human modelling software, and makes it possible to evaluate the sitting posture comfort in a human-vehicle system with various human anthropometric parameters. How this digital evaluation system for car seat comfort design is fitted in the Industry 4.0 framework is also proposed.

Abstract. Vehicle vibration has direct impact on human riding comfort. Against the needs of vehicle man-machine interface design and analysis in the dynamic environment, this paper made the simulation and experimental study of human riding comfort of man-automobile system in dynamic environment. A man-automobile system biomechanics simulation model was constructed in the software system of ADAMS/View and LifeMOD. Through the simulation of the road roughness, different road surfaces, as the vibration exciting, were added to the man-automobile system to dynamically analysis and study the human vibration characteristics under various running states. On the SA30-S802/ST electromagnetic vibration table, human vibration response of manautomobile in dynamic environment was test. Research results show that the man-automobile system biomechanics simulation model can make the simulation and evaluation study of human riding comfort effectively and provide a efficient means for the design and analysis of vehicle human-machine interface under dynamic environment, and have important technical significance for evaluating rapidly the human riding comfort of man-machine system (automobile, tractor, tank and so on).
