36、tion transmission to the occupants of any type of seat used in vehicles and mobile off-road machinery.Application standards for specific vehicles should refer to this part of ISO10326 when defining the test input vibration that is typical for the vibration characteristics of the type or class of veh
37、icle or machinery in which the seat is to be fitted.3 GeneralThe measurement and assessment methods given in this part of ISO10326 comply with the present practice standardized in ISO2631-1. The measuring equipment and the frequency weightings shall be in accordance with ISO8041.NOTE 1In order to ma
38、ke tests in both horizontal directions, xand y , the seat may be turned90 on the platform.4 Instrumentation4.1 Acceleration transducersThe measuring systems selected for the evaluation of vibration at the seat mounting base or platform of the vibration simulator and that selected for the evaluation
39、of vibration transmitted to the seat occupant, or to an inert mass when used, shall have similar characteristics.The characteristics of the vibration measuring system, accelerometers, signal conditioning and data acquisition equipment, including recording devices, shall be specified in the relevant
40、application standard, especially the dynamic range, sensitivity, accuracy, linearity and overload capacity.! Drivers, staff and passengers of vehicles (land, air or water) and mobile machinery are exposed to mechanical vibration which interferes with their comfort, working efficiency and, in some ci
41、rcumstances, safety and health. Such vehicles and mobile machines are often fitted with seats that are designed and made in accordance with current state-of-the-art with regard to their capacity tocontrol or reduce transmitted whole-body vibration. To assist in the development of such seats,specific
42、test codes have been, or are being, produced to evaluate the performance of seats. The following basic requirements have therefore been developed to give guidance for the specification of laboratory testing of vibration transmission through a vehicle seat to the occupant, and for the evaluation of t
43、he ability of a seat to control the shock arising from over-travel of the suspension.“This part of ISO 10326 specifies basic requirements for the laboratory testing of vibration transmission through a vehicle seat to the occupant. ! These methods for measurement and analysis make it possible to comp
44、are test results from different laboratories for equivalent seats.“! The primary test for the vibration characteristics of the seat involves measurements under conditionswhich simulate the range of actual uses of a vehicle or machine. For applications where occasional severe shocks or transient vibr
45、ation can be expected (and in particular for seats whose suspension travel is short, such as those intended for use on industrial trucks or off-road vehicles), in addition to the damping test, a secondary test is required to ensure that the seat responds acceptably. Machinery-specific standards shal
46、l give guidance on the need for this secondary test which comprises a method forassessing the accelerations associated with impact with the suspension end-stops when over-travel occurs. The test is described in Annex A.“ISO 13090-1, Mechanical vibration and shock Guidance on safety aspects of tests
