A HIGH FREQUENCY FATIGUE DYNAMIC LOADING TEST MACHINE FOR RAILWAY FASTENER ELASTIC STRIPS

摘要

The invention relates to a high frequency fatigue dynamic loading test machine for railway fastener elastic strips, comprising a body frame (1), a motor (2), a transmission shaft mechanism (3), a loading connecting rod mechanism (4), a loading block (5), an elastic strip clamping base structure (6), a protective cover (7) and a frame table top (8), which is characterized in that the transmission shaft mechanism (3) comprises a small belt pulley (21) on an output shaft of the motor (2), a camshaft (31), a large belt pulley (33) and a cam (34), wherein the small belt pulley (21) and the large belt pulley (33) are connected through a toothed belt, the large belt pulley (33) and the cam (34) are mounted on the camshaft (31), the loading connecting rod mechanism (4) contacts the cam (34), the other end of the loading connecting rod mechanism is connected with a loading block (5),and the loading block (5) is connected with the elastic strip test sample (62) installed on the elastic strip clamping base structure (6). Compared with the prior art, the loading frequency outputed by the loading block in the invention can reach 5,000 Hz, and the invention has the advantages of being safe and convenient to be observed and the like.
