Research on strength of roadheader conical picks based on finite element analysis

This paper presents finite element analysis of the strength of roadheaher conical picks. Failure forms of conical picks are investigated, and the FE model of conical pick is established which is based on ANSYS. The static analysis is carried out according to the load calculated by empirical formula and the deformation map and stress distribution is obtained. The results show that the maximum stress of conical pick appeared in the tool bit. In order to examine the result of static analysis, contact analysis of conical pick cutting process is researched, and a consistency is achieved. The finite element analysis not only offers a new way of studying the strength of conical picks and improving the service life of the pick, but also provides a reliable theoretical basis for the selection, design and use of the conical picks. © Cao et al.; Licensee Bentham Open.
