본 발명은 노면 상태에 따른 주행소음을 측정하기 위한 타이어 주행소음 측정장치에 관한 것으로서, 특히 타이어의 마찰소음을 도로상에서 직접 정확하게 측정할 수 있는 이동식 타이어 주행소음 측정장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire running noise measuring apparatus for measuring running noise according to a road surface condition. In particular, the present invention relates to a movable tire running noise measuring apparatus capable of directly and accurately measuring friction noise of a tire on a road.

타이어의 마찰소음 등과 같이 주행 중 자동차로부터 발생하는 소음은 탑승자의 승차감을 저해하는 것은 물론이고 도로 주변의 주거 환경을 크게 해치기 때문에 차량이나 타이어 설계시 소음을 최소화하기 위한 연구가 꾸준히 진행되고 있다. 더불어, 주행 중인 자동차에서 발생하는 소음의 원인을 찾아내기 위하여 노면 상태에 따른 주행소음을 측정하여 분석할 수 있는 여러 가지 측정장치들과 방법들이 개발되어 사용되고 있다.The noise generated from the vehicle while driving, such as the friction noise of the tire, not only impairs the ride comfort of the occupant, but also greatly damages the residential environment around the road. In addition, various measurement devices and methods have been developed and used to measure and analyze driving noise according to road conditions in order to find the cause of noise generated in a driving car.

그 중에서도 자동차가 주행할 때 발생하는 타이어 마찰소음은 차량을 방음시설이 된 무향실 내에서 실제 노면과 유사한 표면을 가진 주행 드럼을 이용하여 주행시켜 측정하거나 타이어에 직접 소음측정장치를 장착한 다음 실제 노면 주행을 통해 측정하는 방식이 주로 이용되어 왔다.In particular, tire friction noise generated when a car is driven is measured by driving the vehicle using a running drum having a surface similar to the actual road surface in an anechoic room equipped with a soundproofing facility, or by installing a noise measuring device directly on the tire. The method of measuring by driving has been mainly used.

그러나, 일본특허공개 1998-090125의 소음측정방법과 같이 실내 무향실에서 엔진을 멈추고 드럼만을 이용하여 타이어의 소음을 측정하는 종래 소음측정방법의 경우에는 실제 노면과 유사한 조건들을 가진 드럼들을 교체해가면서 노면 상태에 따른 소음의 변화를 측정해야 하기 때문에 측정 작업이 매우 번거로울 뿐만 아니라, 한정된 수량의 주행 드럼에 매우 다양한 형태로 나타나는 실제 노면의 상태를 정확하게 반영하기 어렵기 때문에 실제 주행시에 발생하는 마찰 소음을 정확하게 측정하는데 상당한 어려움이 있었다.However, in the conventional noise measuring method of stopping the engine in an indoor anechoic chamber and measuring the tire noise using only the drum, such as the noise measuring method of Japanese Patent Laid-Open Publication No. 1998-090125, the road surface state is replaced by replacing drums having conditions similar to those of actual road surfaces. It is not only cumbersome to measure the change of noise due to the noise, but also it is difficult to accurately reflect the actual condition of the road surface that appears in various forms on a limited number of running drums. There was a significant difficulty.

그리고, 미국합중국특허 6529838호의 자동차 소음측정방법 등과 같이 측정장비를 차량에 직접 장착한 후 실제 노면 주행을 통해 소음을 측정하는 방법의 경우에는 주변에서 유입되는 소음으로 인해 실제 타이어와 노면 사이에서 발생하는 타이어 마찰소음을 정확하게 측정하기 어렵다는 문제점이 있었다.And, in the case of measuring the noise through the actual road driving after the measurement equipment is directly mounted on the vehicle, such as the vehicle noise measurement method of the United States Patent No. 6529838, it occurs between the actual tire and the road surface due to the noise flowing from the surroundings Tire friction noise was difficult to measure accurately.

본 발명은 상술한 바와 같은 종래 주행소음 측정장치 및 측정방법의 문제점을 개선하기 위하여 안출된 것으로, 실제 노상에서 주변의 소음을 차단한 상태에서 타이어의 마찰소음을 정확하게 측정할 수 있을 뿐만 아니라 특히 이동이 가능하여 노면의 조건이 다른 도로로 이동해가면서 노면 조건에 따라 실제 주행시 발생하는 소음을 보다 정확하고 간편하게 측정할 수 있는 이동식 타이어 주행소음 측정장치를 제공하는데 그 목적이 있다.The present invention has been made to improve the problems of the conventional running noise measuring apparatus and measuring method as described above, it is possible to accurately measure the friction noise of the tire in the state in which the surrounding noise in the actual road, as well as to move in particular The purpose of the present invention is to provide a mobile tire running noise measuring device that can more accurately and easily measure the noise generated during actual driving according to the road conditions as the road conditions move to different roads.

Characterized in that comprises a.

이상의 구성에 있어서, 상기 방음터널은 노면을 따라 이동시킬 수 있는 이동수단을 포함하여 이루어진 것이 바람직하다.In the above configuration, the soundproof tunnel preferably comprises a moving means that can be moved along the road surface.

이상과 같은 구성으로 이루어짐에 따라, 본 발명에 따른 이동식 타이어 주행소음 측정장치는 노면 상태에 따른 차량의 타이어 마찰소음을 장소를 이동해가면서 실제 노상에서 실차 상태로 주행하는 자동차로부터 직접 정확하게 측정할 수 있다.According to the configuration as described above, the mobile tire running noise measurement apparatus according to the present invention can accurately measure directly from the vehicle running in the actual vehicle state on the road while moving the tire friction noise of the vehicle according to the road surface condition. .
