Dynamics Analysis on Roadheader Cutting Head Based on LS-DYNA
The dynamic performances of head cutter for boom-type excavator were researched, and the corresponding dynamic equilibrium equations were derived. Based on the explicit dynamics analysis techniques of the Software ANSYS/LS-DYNA, transient dynamic analysis was carried out to simulate the cutting process of head cutter, and the main kinetic parameters were achieved. Finally, the cutting performan...
متن کاملStudy on Roadheader Cutting Load at Different Properties of Coal and Rock
The mechanism of cutting process of roadheader with cutting head was researched, and the influences of properties of coal and rock on cutting load were deeply analyzed. Aimed at the defects of traditional calculation method of cutting load on fully expressing the complex cutting process of cutting head, the method of finite element simulation was proposed to simulate the dynamic cutting process...
متن کاملCharacteristic Analysis of Current Spectrum on Shearer Cutting Load
According to the disadvantages of former shearer cutting load measuring method and its low antiinterference ability, this paper proposes a new shearer cutting load measuring method based on the current spectrum. On the basis of load analysis of shearer cutting unit drive system, the theoretical models are established between cutting load and cutting motor current. Simulated load test to the ele...
متن کاملResearch on the 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 based on ANSYS. The static analysis is carried out according to the load calculated by empirical formula and the deformation map and stress distribution are obtained. The results show that the maximum stress of ...
