タイヤ業界向けの測定・試験システム

最高の性能を最大限に活用

タイヤ業界は、タイヤの開発・製造のためにタイヤ試験で使用する測定システムにも適用される要求事項の増加に直面しなければなりません。自動車用タイヤは、これまで以上に高い期待に応えなければならず、より厳しい国際規格に準拠しなければなりません。燃費や騒音、そしてより厳しい安全基準や環境基準に焦点が当てられています。各車両モデルの装備バリエーションが増えれば増えるほど、タイヤの選択肢も増え、結果としてOEMの仕様も個別になるため、タイヤの承認数は増加の一途をたどっているのです。また、各自動車メーカーは、操舵性、スポーツ性能、乗り心地など、異なるタイヤ特性を優先しています。

電気自動車の重量増加や高トルク化などの理由から、エレクトロモビリティでもタイヤの仕様に新たな要件が求められています。荷重が大きくなると、横方向の抵抗を高めたタイヤが必要となり、制動距離も長くなります。転がり抵抗が低ければ、エネルギー効率が向上し、航続距離が伸びます。また、騒音が少ないということは、車内が快適であるということであり、内燃機関の騒音がなくなった今、この基準は非常に重要になってきています。しかし、始動時のトルクが大きいと、摩耗が早くなり、走行性能も低下します。

"オーダーメイド "のタイヤが求められています。柔軟な試験能力と試験時間の短縮が、競争力を維持するための鍵です。

      Characterizing the NVH behavior of tires on the tire test stand

      Disturbing tire noise and vibrations (HSU, NVH) are gaining importance as the transformation of mobility proceeds and the percentage of alternative propulsion systems, respectively of electrified vehicles (EVs, NEVs, PHEVs), continues to increase. Thanks to piezo-based measuring hubs specifically developed for highly dynamic measurements, you can quickly identify the critical frequency ranges and non-uniformities of your tire

      You want to
      • Identify and analyze tire non-uniformities in all directions (NVH, HSU, flatspot, cleat)
      • Determine the tires' key data
      • Validate the dynamic parameters of tire models
      Method
      • Accurately measure dynamic force variations in all three directions: radial force variation (RFV), lateral force variation (LFV) and tangential force variation (TFV)
      • Evaluate resonances and harmonic oscillations in the tire or the entire wheel

      Determining tire rolling resistance on the tire test stand, as well as of electrified vehicles (EVs, NEVs, PHEVs)

      You want to
      • Provide proof that rolling resistance design is optimal: a balance between minimum fuel consumption/minimum CO2 emissions and maintenance of safety-relevant tire characteristics and running performance 
      • Define the rolling resistance that is disclosed to the end customer in the form of the tire label
      Method
      • Perform rolling resistance measurements on the tire test stand based on ISO 28580, SAE J1269 and ECE R117
      • Accurately measure the rolling resistance based on the force measurement method. For this purpose, both force directions (Fx and Fz) are measured directly in the measuring hub. Parasitic influences are largely eliminated because the force sensors are positioned directly at the point of load application.
