### 1229. Validation of bucket wheel drive component model

Keywords: bucket-wheel excavator, vibration monitoring, numerical model, torque arm. 1. Introduction The bucket-wheel excavator is a very dynamic system, with an inherently large number of vibration sources. The bucket wheel drive, or the bucket wheel, is the only assembly that comes into direct contact with the material that is being excavated.
