The development of the automotive industry is conditioned by the application of production technologies, which directly depend on production volumes. Today's development of car production is possible only in conjunction with the volume of production, ensuring both the parameters of assembly and production quality. Their constant monitoring is related to the application of the verification tools and technologies used. Such is the length measurement process that needs to be precise in the automotive industry. The paper analyzes the precision length measurement system and its dynamic characteristics. The research is applied to solve the problems of dynamic processes of a precision length measuring system, and the obtained results can be used in the development of precision systems for other purposes. The obtained results describe the vibrations of the length measuring system housing and the measuring head, which show the weak points of the system at the respective frequencies.

The application of new and advanced production processes plays an important role in the development of the manufacturing industry. This trend is especially relevant to the automotive industry, where each element must ensure high quality requirements. Therefore, automating the automotive manufacturing process is necessary to ensure the highest level of control methods. For this purpose, various sensors are used, the signals of which are analyzed and the control plan itself is adjusted. Experimental investigations of a precision angle encoder were performed in the work. During the research, the dynamic characteristics of the created stand were determined. Experimental studies yielded the results of an experimental study of a precision angle encoder when the system is subjected to shock and harmonic excitation. In order to elucidate the effect of oscillations on the accuracy of a high-resolution coded precision angle encoder, primary electrical signals and their change under oscillations were recorded. Studies have shown that high-resolution code-precision angle encoders have different design responses to dynamic effects depending on the direction of the vibrations acting.
