9、ic Requirements4.1 Longitudinal LoadA vehicle passenger door hinge system, when tested as prescribed under test procedurein 5.1, must be capable of withstanding an ultimate longitudinal load of 11 100 N.4.2 Transverse LoadA vehicle passenger door hinge system, when tested in accordance with the test

10、procedures in 5.2, must be capable of withstanding an ultimate transverse load of 8900 N.5. Static Tests5.1 Longitudinal Load5.1.1 PURPOSETo determine the ability of the vehicle hinge system to withstand a test load in the longitudinalvehicle direction.5.1.2 EQUIPMENTa. Tensile testing machine.b. A

11、typical static test fixture is illustrated in Figure 1.FIGURE 1STATIC LOAD FIXTURES (TRANSVERSE LOAD)SAE J934 Reissued SEP1998-3-5.1.3 OPERATIONa. Attach a test fixture to the mounting provision of the hinge system. Hinge attitude must simulatevehicle position (door fully closed) relative to the hin

12、ge centerline. For test purposes, the distancebetween the extreme end of one hinge in the system to the extreme end of another hinge in the systemis to be set at 406 mm. The load is to be applied equidistant between the linear center of the engagedportions of the hinge pin and through the centerline

13、 of the hinge pin in the longitudinal vehicledirection.b. Apply the test load at a rate not to exceed 50 mm/min until failure. Failure to consist of separation ofeither hinge. Record maximum load.5.2 Transverse Load5.2.1 PURPOSETo determine the ability of the vehicle hinge system to withstand a test

14、 load in the transversevehicle direction.5.2.2 EQUIPMENTa. Tensile testing machine.b. A typical static test fixture is illustrated in Figure 1.5.2.3 OPERATIONa. Attach the test fixture to the mounting provisions of the vehicle hinge system. Hinge attitude mustsimulate vehicle position (door fully cl

15、osed) relative to the hinge centerline. For test purposes, thedistance between the extreme end of one hinge in the system to the extreme opposite end of anotherhinge in the system is to be set at 406 mm. The load is to be applied equidistant between the linearcenter of the engaged portions of the hi

16、nge pins and through the centerline of the hinge pin in thetransverse vehicle direction.b. Apply the test load at a rate not to exceed 50 mm/min until failure. Failure to consist of separation ofeither hinge. Record maximum load.6. Single Hinge Evaluation6.1 IntroductionIn some circumstances, it may

17、 be necessary to conduct evaluations of individual hinges in ahinge system. In such cases, the results for an individual hinge, when tested in accordance with theprocedures in 6.2, shall be such as to indicate that system requirements in 4.1 and 4.2 are met. (Example: Anindividual hinge in a two-hin

18、ge system must be capable of withstanding 50% of the load requirements of thetotal system.)6.2 Test Procedures6.2.1 LONGITUDINAL LOADAttach a test fixture to the mounting provision of the hinge. Hinge attitude mustsimulate the vehicle position (door fully closed) relative to the hinge centerline. Fo
