Title:
TRAIN RUNNING LOAD SIMULATING EXCITER AND TRAIN RUNNING LOAD SIMULATING EXCITATION METHOD
Document Type and Number:
Japanese Patent JP3718662
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a train running load simulating exciter capable of preferably executing a test for comprehending the frequency characteristics of a ground side system having a test rail track or an accelerated test for simulating a multitude of passages of train wheels on the test rail track in a short period of time, and a train running load simulating excitation method for preferably executing the tests.
SOLUTION: After the rotation of an unbalanced weight is started and exciting force generated from the unbalanced weight reaches a set value, a relative phase angle between a movable eccentric weight and a fixed eccentric weight is set so that the phase angle corresponds to the rotational frequency of the unbalanced weight detected with a velocity sensor by using map data expressing relation of the rotational frequency of the unbalanced weight with a relative phase angle between the movable eccentric weight and the fixed eccentric weight in the unbalanced weight in order to keep the exciting force constant.
