LOOSENING TESTER CAPABLE OF PRECISELY CONTROLLING LATERAL LOAD

摘要

A loosening tester capable of precisely controlling a lateral load employs a load control motor (17) to control generated lateral displacement load and lateral force load, and controls, by means of a signal fed back by a sensor (8), the load control motor (17), such that the generated lateral force load maintains substantially stable. The tester can provide stable lateral displacement load and lateral force load, thereby adapting to experiments which simulate different scenarios in which screws are acted upon by loads.
