IMPACTOR FOR NOISE MEASUREMENT APPARATUS OF VEHICLE DOOR

摘要

PURPOSE: An impactor for a noise measuring device of a vehicle door is provided to accurately measure unique noise values on a door trim since unnecessary metallic noise does not occur. CONSTITUTION: An impactor for a noise measuring device of a vehicle door comprises a body(11), a connecting member(13) and a striking member(15). An upper coupling groove(11a) and a lower coupling groove(11b) are formed on both ends of the body. The body detachably coupled to an operating unit through the upper coupling groove. The connecting member is detachably coupled to the lower coupling groove of the body. The striking member is inserted into the front side of the connecting member. The striking member is formed from a material, which can apply load by striking the impact point of the door trim in operation of the operating unit and prevent the metallic noise generation in striking of the impact point.
