Description

本発明は、列車や自動車、航空機など乗り物の客室における乗り心地評価を行う複合環境試験装置に関するものである。   The present invention relates to a combined environmental test apparatus that evaluates ride comfort in passenger cabins of vehicles such as trains, automobiles, and aircraft.

従来、客室内環境模擬装置として、様々な客室内環境を模擬できるものが提案されている（下記特許文献１参照）。
図４は客室内環境模擬装置の模式図である。
この図において、１０１は固定部、１０２は揺動装置本体、１０３は模擬客室、１０４は空調機の室外機、１０５はサーボアンプ、１０６は揺動制御装置、１０７は昇降装置である。 2. Description of the Related Art Conventionally, as a cabin environment simulation device, a device capable of simulating various cabin environments has been proposed (see Patent Document 1 below).
FIG. 4 is a schematic diagram of the cabin environment simulation device.
In this figure, 101 is a fixed part, 102 is a swinging device body, 103 is a simulated cabin, 104 is an outdoor unit of an air conditioner, 105 is a servo amplifier, 106 is a swing control device, and 107 is a lifting device.

また、列車や自動車、航空機など乗り物の客室の乗り心地評価を行うために、体感振動としては高周波域の評価を、室内騒音としては中高周波域の評価をそれぞれ別個に計測するようにしていた。
特開２００３−２９５７５０号公報 In addition, in order to evaluate the ride comfort of a passenger cabin such as a train, an automobile, and an aircraft, the high frequency range is evaluated as the sensation vibration, and the middle high frequency range is evaluated as the room noise.
JP 2003-295750 A

交通機関の快適性の指標である乗り心地については、振動周波数に対する人体の感度に合わせた周波数重み付けをフィルターとした指標が用いられてきた。
図５は従来のＩＳＯ２６３１−１に基づく等感覚曲線を示す図であり、横軸に周波数（Ｈｚ）、縦軸に周波数重み付け（ｄＢ）を示している。
図５から明らかなように、人体の振動周波数に対する感度は、上下方向では５Ｈｚ、左右・前後方向では２Ｈｚ付近が最も高く、これより低周波および高周波に行くに従い、感度は低下するとされている。 As for the ride comfort, which is an index of comfort of transportation, an index using a frequency weighting according to the sensitivity of the human body to the vibration frequency as a filter has been used.
FIG. 5 is a diagram showing an isosensory curve based on conventional ISO2633-1, where the horizontal axis represents frequency (Hz) and the vertical axis represents frequency weighting (dB).
As is clear from FIG. 5, the sensitivity to the vibration frequency of the human body is highest at 5 Hz in the vertical direction and around 2 Hz in the left / right / front / rear direction, and the sensitivity decreases as the frequency becomes lower and higher.

一方、軽量車体を有する高速鉄道車両や航空機等では、乗り心地に影響を与える振動加速度の周波数域は、在来鉄道等の交通機関にはほとんどない高周波数成分（２０〜８０Ｈｚ）を多く含んでいる。この周波数帯は、従来の評価方法では人体の感度特性は低いとされ、乗り心地に大きく影響しないとされるが、実際には乗り心地に大きく影響しており、従来の評価法では体感との乖離があった。なぜならば、この周波数帯域は、従来法で重み付けの高い１０Ｈｚ以下の成分に比べると、振動の大きさとしての人体感受性はあまり高くないものの、ビビリとして皮膚表面では十分知覚される成分であること、また、音域として低周波の可聴域に重なるので、低周波騒音として知覚されることで顕在化するためと思われる。   On the other hand, in a high-speed railway vehicle or an aircraft having a lightweight vehicle body, the frequency range of vibration acceleration that affects the ride comfort contains many high-frequency components (20 to 80 Hz) that are hardly found in transportation such as conventional railways. Yes. This frequency band is considered to have a low sensitivity characteristic of the human body in the conventional evaluation method and does not significantly affect the ride comfort, but in fact, it has a great influence on the ride comfort. There was a divergence. This is because this frequency band is a component that is sufficiently perceived on the skin surface as chatter, although the human body sensitivity as a magnitude of vibration is not so high as compared with a component of 10 Hz or less which is weighted by the conventional method. Also, since it overlaps the low frequency audible range as the sound range, it seems to be manifested by being perceived as low frequency noise.

以上より、この高周波振動領域の乗り心地評価には、高周波振動に加えて超低周波音・低周波音による影響も考慮する必要がある。さらに、客室内の騒音再現には、従来の中高音に加えて、超高周波音の影響も考慮することが必要である。
本発明は、上記状況に鑑みて、乗り心地評価に、高周波振動に加えて超低周波音・低周波音、超高周波音による影響も考慮した、複合環境試験装置を提供することを目的とする。 From the above, it is necessary to consider the influence of ultra-low-frequency sound and low-frequency sound in addition to high-frequency vibration in evaluating riding comfort in this high-frequency vibration region. Furthermore, in order to reproduce the noise in the cabin, it is necessary to consider the influence of super high frequency sound in addition to the conventional medium and high sounds.
In view of the above circumstances, an object of the present invention is to provide a composite environment test apparatus that takes into account the effects of ultra-low frequency sound, low-frequency sound, and ultra-high frequency sound in addition to high-frequency vibration in riding comfort evaluation. .
