It is applicable to instantaneous data or averaged data. The basic quantity that describes the intensity of the human body vibration environment is acceleration, with the unit of m/s2. In physiology, vibration intensity is often expressed in g as the unit of acceleration. When this unit is involved, the international standard gravity acceleration value g (g=9.80665m/s) should be used for unit conversion. 3.4 Vibration rating
In biodynamics, a subjective assessment of the intensity (see 3.52 of GB/T2298 for the definition of vibration intensity) or strength of human vibration exposure is made using an assessment scale or a corresponding numerical instrument, which is obtained based on psychological test methods. 3.5 Ride characteristics
In a vehicle, the measurable motion environment (including vibration, shock, continuous linear acceleration and rotational acceleration or noise related thereto) to which passengers are subjected.

4.1 Biodynamics
The science of the physical, biological, mechanical (inertial) properties and response characteristics of the tissues, organs, components and systems of the human body or a simulated body of a human. It includes exobiodynamics (for external forces or motion) and endobiodynamics (related to the mechanical activities of the body).
basicentric coordinate system4.2 Reference coordinate system
A right-handed orthogonal coordinate system whose origin is located at (or relative to) a point on a contact surface or structure (e.g., the floor of a vehicle) and from which the mechanical vibration (or shock) is considered to be transmitted to the human body. 4.3 Anatomical coordinate system The right-handed orthogonal coordinate system commonly used in biodynamics, with its origin located in the human body or a human simulation, and with directions defined by fixed (skeletal) anatomic landmarks. The body part corresponding to the defined anatomical coordinate system should be indicated in brackets. For example, "anatomical coordinate system (hand)", "anatomical coordinate system (head)", etc. When the body direction and posture change, the coordinate system will move with the body part. 4.4 Contact surface The surface or interface through which mechanical vibration (or shock) is transmitted to the human body or a human simulation. In general, the main mechanical driving point of the vibration or shock motion should be considered to be located at the center of the plane of the contact surface. 4.5 Whole-body vibration (or shock) Mechanical vibration (or shock) transmitted to the whole body, usually transmitted through the area where the body contacts the support surface (which is subject to vibration or shock motion) (such as the buttocks, the bottom of the feet, and the back in the supine position). Commonly abbreviated WBV.

Typical burst vibrations include quasi-harmonic vibrations with exponentially decaying amplitudes that appear after the impact input of a resonant system of the human body; or vibrations with a spindle-shaped amplitude envelope (for example, bridge deck vibrations excited by the passage of heavy vehicles); or a short-term random vibration (such as the response of an aircraft to isolated gusts of air turbulence, or the response of a ship to a collision, etc.). 5.9 Repetitive shock; repeated shock In biodynamics, a series of short (less than 1s) impact movements or bursts of quasi-steady-state vibrations that affect the human body. Regular or repetitive shocks that often occur more than once per second can be regarded as a continuous vibration. 5.10 Impulsive vibration In biodynamics, when the duration of each impact and the interval between impacts are shorter than the natural transient response or natural vibration period of the stimulated person, the quasi-steady-state vibration or continuous transient vibration generated by fast repetitive impact motion. The hand-transmitted vibration with strong periodicity generated by hand-held reciprocating power tools is generally considered as impulsive vibration. 5.11 Exposure time
The actual or equivalent (calculated according to a certain standard method) duration of mechanical vibration (or repetitive impact) acting on the body. The total exposure time refers to the duration of human exposure to vibration during the working day. For a type of vibration that is intermittent, interrupted and/or has different intensities, its equivalent total exposure time can be calculated. 5.12 Intermittent exposure - interrupted exposure; discontinuous exposure Human quasi-steady-state vibration or continuous vibration exposure interrupted by vibration-free periods with a certain time course (number of occurrences and duration) (usually occurs in occupational hand-transmitted vibration). This interruption is mandatory or electronically controlled. 5.13 Intermittent vibration Intermittent vibration Repeated continuous vibration separated by vibration pauses, or vibration levels below the human perception threshold and interference threshold, or by significant changes in the vibration level (or its characteristics) during the intervals. The intervals are usually irregular.
5.14 Long-duration vibration exposure (or repetitive shock exposure) long-duration vibration exposure (or repetitive shock exposure) GB/T 15619-. 1995

This value is obtained through a certain calculation method or signal processing that reflects the human response characteristics, and is a function of vibration frequency or exposure time. When the word "level" is included in the term, it means referring to a standard vibration acceleration level. 6 Terms for human vibration or shock response

The characteristic symptom of this disorder is a well-defined localized whitening of the skin of the fingers accompanied by numbness when the hands or the whole body are exposed to cold. It usually continues as long as the precipitating factor is present and may gradually develop. After a latent period after the initial exposure, the typical symptoms of the disorder will appear in one or more fingers. The distribution of these fingers generally corresponds to the strongest vibration exposure, and the greater the exposure dose, the more fingers are affected.
Commonly abbreviated VWF. Synonym: occupational Raynaud's disease. 2 hand-arm vibration syndrome hand-arm vibration syndrome 6.12
A group of symptoms that occur in some workers using hand-held vibrating tools, which symptoms may not be caused by vibration alone. These symptoms include: (1) disturbance of blood circulation in the skin of the fingers, i.e., Raynaud's sign; (2) disturbance of nerve activity in the hand or forearm (pain, paresthesia, increased sensory threshold of the hand); (3) motor disorders (pain and weakness in the hand and forearm, occasionally arthritis of the elbow and wrist).
