Step I, first, after bushing central shaft (302) is fitted into torsion beam bushing (301);Then, by bushing central shaft (302) articulated joint (307) is connect with bushing rear-inclined frame (306) after bushing;Secondly, bushing pushes screw rod (312) and drives lining It is mobile to cover c-type snap-gauge (311), and clamps bushing central shaft (302);Again, bushing lower mounting seat (315) is installed on bushing Seat (316) is connected by bushing pairing bolt (313);And then, adjustment bushing studdle (317), bushing branch fastener (318) Upper bushing lower mounting seat (315) is pushed up, until corresponding bushing inclination technical face (319) is vertical with fatigue strength test head;Finally, Bushing nut (314) is mounted on bushing central shaft (302);
Step II, first, lifting hydraulic cylinder (3) drive fatigue strength test head to decline;Then, fatigue strength test head is by inserting Enter in bushing work through-hole (320), and is contacted with pressure with rear torsion beam bushing (301);Finally, start fatigue strength test head pair Torsion beam bushing (301) progress vibrating fatigue is slightly tested afterwards.
5. rubber performance test method according to claim 1, it is characterised in that:All-steel cord extracts high/low temperature fatigue out Test method extracts high/low temperature fatigue test device out by means of all-steel cord, and this approach includes the following steps,
Step 1, first, by the upper ends for surveying pulling force test specimen (408) to surveying in center of drag slot (419) and will be in survey pulling force Heart slot (419) lower end passes through through-hole;Then, it surveys pulling force handle (421) and rotates and survey pulling force will be pressed under survey pulling force eccentric wheel (422) On test specimen (408);Secondly, pulling force upper binding head (406) will be surveyed to be mounted on survey pulling force on grappling fixture (402);Again, pulling force will be surveyed Lower deck (405), which is mounted on, surveys under pulling force on grappling fixture (403);And then, it surveys pulling force side catch bar (413) and drives survey pulling force elasticity Plate (417), which clamps, surveys pulling force test specimen (408) lower end;
Further include step 3 after step 1, step 3 includes one kind in following scheme;
Scheme one starts lifting hydraulic cylinder (3) and upper frame (2) is pushed to rise drawing survey pulling force test specimen (408) to setting stroke first; Then, start and survey pulling force vibrating motor (401) to surveying pulling force test specimen (408) progress testing fatigue, pulling force test specimen is surveyed until drawing (408) it is broken, secondly, according to the vibration information for obtaining surveying pulling force vibrating motor (401), obtains surveying pulling force test specimen (408) fatigue Test data;
Scheme two starts lifting hydraulic cylinder (3) and pushes upper frame (2) rising that survey pulling force test specimen (408) is drawn to survey pulling force until drawing first Test specimen (408) is broken;Then, it according to lifting hydraulic cylinder (3) pressure value, obtains surveying pulling force test specimen (408) pull stress test number According to.
6. rubber performance test method according to claim 5, it is characterised in that:Between step 1 and step 3 also Including step 2;
Step 2,;Test telescopic cylinder (514) push to test thermal-insulating body (515), which covers, surveys pulling force test specimen (408);Secondly, it closes Close test front apron (518);Finally, it carries out being heated to assigned temperature.
