Radial turbine and compressor wheels form essential cornerstones of modern internal combustion engines in terms of economy, efficiency and, in particular, environmental compatibility. As a result of the introduction of exhaust gas turbochargers in the extremely important global market for diesel engines, higher engine efficiencies are possible, which in turn reduce fuel consumption. The associated reduced exhaust emissions can answer questions that results from environmentally relevant aspects of the engine development. In shipping, the international Maritime Organisation (IMO) prescribes the step-by-step reduction of nitrogen oxide and other types of emissions. To reduce these emissions, various systems are being developed, in which turbochargers are an important part. The requirements for the reliability and service life of turbochargers are constantly increasing. Turbocharger blade vibration is one of the most important problems to be solved when designing the rotors. In the case of real rotors, so-called mistuning arises, which is a slight deviation of the properties of the individual blades from the design parameters. The article deals with an effective method of mistuning identification for cases of integrated bladed discs of marine engine turbochargers. Unlike approaches that use costly scanning laser Doppler vibrometers, this method is based on using only a simple laser vibrometer in combination with a computational model of the integrated bladed disc. The added value of this method is, in particular, a significant reduction in the cost of laboratory equipment and a reduction in the time required to obtain the results.

船用涡轮增压器集成叶片盘的有效失误识别方法。

就经济性，效率，尤其是环境兼容性而言，径向涡轮和压缩机叶轮是现代内燃机的重要基石。通过在极为重要的柴油发动机全球市场中引入废气涡轮增压器，可以提高发动机效率，进而降低燃油消耗。相关的减少的废气排放可以回答发动机开发中与环境相关的方面所引起的问题。在运输方面，国际海事组织（IMO）规定了逐步减少氮氧化物和其他类型排放物的规定。为了减少这些排放，正在开发各种系统，其中涡轮增压器是重要的部分。涡轮增压器的可靠性和使用寿命要求不断提高。涡轮增压器叶片振动是设计转子时要解决的最重要问题之一。在实际转子的情况下，会产生所谓的雾化，这是单个叶片的特性与设计参数之间的微小偏差。本文探讨了一种用于船用发动机涡轮增压器集成叶片盘的误识别的有效方法。与使用昂贵的扫描激光多普勒测振仪的方法不同，此方法基于仅使用简单的激光测振仪结合集成刀片式磁盘的计算模型的方法。该方法的附加值尤其是
