Abstract

Mathematical models of the manual grinding machine (MGM) ИП2014П were given and their analysis in idling and working stroke conditions was performed. An adequacy of the presented mathemati­cal models with the real modeling object was achieved.

The results of the analysis of existing standard requirements to unbalanced masses of abrasive wheels based on the compliance with requirements to local vibrations, affecting the operator were provided. By modeling vibrations on the left handle of the MGM in the idling conditions, it was found that the wheel imbalance is equal to 0.004 mкр on its radius, i. e., at its maximum permissible value according to GOST 23182-78 does not guarantee fulfilling sanitary standards.

An assessment of the vibration safety of the MGM in idling and working stroke conditions with abrasive wheels made using tradi­tional shaping technology was carried out. It was found that with the existing ПП 150х25х32 wheel shaping technology, maximum error of the wheel shape and placing it on the spindle of the MGM lead to the vibration excitation on the left handle of the MGM in the idling conditions in the range of (33÷49) mm/s, and (26÷56) mm/s in the working stroke conditions, which is on average 1.6 times higher than sanitary standards.
