METHOD FOR CUTTING HEAD DESIGN USING DATABASE

摘要

According to the present invention, in a method to design a shape of a cutting head (100) installed in a load head (1) by using a database, the cutting head (100) includes a cutting head body (110) and multiple pick cutters (120) penetrating the cutting head body (110). The method to design a shape of a cutting head (100) installed in a load head (1) by using a database includes a first step (S100) of estimating the whole power of the load head (1) by using an excavation section and physical properties of rock as an input variable; a second step (S200) of calculating the own weight of the load head (1) based on the whole power; a third step (S300) of assuming the maximum power of the cutting head (100) within a range of the whole power; a fourth step (S400) of calculating the width (a) and diameter (b) of the cutting head (100) based on the maximum power estimated at the third step; and a fifth step (S500) of determining a circumferential direction gap (c) and a horizontal direction gap (d) of the pick cutters (120) through a cutting test based on the width (a) and the diameter (b).
