| Abstract: | Using force analysis of tractor hydraulic lift system loaded by inclined hydraulic cylin-der,it is pointed out that the test-loading error of the testing bench of such a design hasgone beyond the error limit of force measurement according to international and domesticcurrent test standards of agricultural tractor.This design was applied widely in the world.This paper presents a formula to calculate the test-loading error,and raises a method tomodify the test-data in order to compensate the error.It provides a reference for the develop-ment of new test benches and the renew of existed ones. |
