2、ancement of engineering applicable to agricultural, food, and biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally agricultural fie

3、ld equipment, farmstead equipment, structures, soil and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management.

The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance with applicable ordin

ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“, regardless of the rev

6、ision approval date. Newly developed Standards, Engineering Practices and Data approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard requires verific

7、ation by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substant

8、ial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Addition

9、ally, procedures of ASABE require that action be taken periodically to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers.

32、rface of the vehicle at one point, and A and B are two points thus defined which correspond to two wheels, both of which are either steering or powered wheels, situated respectively at the two ends of the same real or imaginary axle See Figure 1. Note 1 to entry: The mid-plane of the dual wheels bei

33、ng equidistant from the inner edge of one wheel and the outer edge of the other, the straight line is, in this particular case, the intersection of the mid-plane of the dual wheels and the vertical plane passing through the axis of the axle pin. Note 2 to entry: Adapted from ISO 612:1978, Clause 5.

34、Note 3 to entry: The longitudinal median plane may also be applied to track-laying tractors.

35、 Note 1 to entry: If A and B are the two points thus defined for the wheels on the same axle of the tractor, then the track width is the distance between points A and B. The track may be defined for both front and rear wheels. Note 2 to entry: Where there are dual wheels, the track width is the dist

36、ance between two planes, each of which is the median plane of the pairs of wheels. Note 3 to entry: For track-laying tractors, the track width is the distance between the median planes of the tracks. 3.10 vertical reference plane plane established before any application of loading, generally longitu

38、udinal median plane of the tractor is used. Normally, the reference plane coincides with the longitudinal median plane of the tractor. 3.11 seat reference plane vertical plane generally longitudinal to the tractor, passing through the seat index point and to the steering wheel centre and which is us

39、ed for establishing the clearance zone Note 1 to entry: This plane is established at the beginning of the series of tests and normally coincides with the longitudinal median plane of the tractor. This plane is assumed to move horizontally with the seat and steering wheel during loading but to remain

40、 perpendicular to the tractor or the floor of the ROPS if the latter is resiliently mounted. When a steering wheel does not exist, a vertical plane passing through the SIP and parallel to the longitudinal median plane of the tractor is used. 3.12 wheelbase distance between the vertical planes passin
