Technique of visualization of dynamic characteristics of electromagnetic strike machines

Abstract

Abstract At present, the use of pulsed linear electromagnetic engines in the drive of strike machines for immersing rod elements in soil, percussive drilling of shallow wells and dynamic sounding of soils is recognized to be quite effective. The transient time in linear electromagnetic engines of such devices is not more than 0.25 s, which makes it difficult to obtain the most complete information about their characteristics. The solution to this problem with the help of traditional technical means is found difficult. Experimental studies of the working processes of pulsed linear electromagnetic engines of strike machines were carried out. The study of work patterns, the development of recommendations for the rational selection of individual design and operating parameters allow for maximum mechanical energy at the engine output with the greatest possible efficiency. The technique of visualization of the dynamic characteristics of strike machines with pulsed linear electromagnetic engines using a multifunctional analog-to-digital converter board is considered.
