Abstract

The invention relates to a disk cutter geological adaptability design method based on CAD / CAE and optimal design, which comprises the following steps of: collecting traditional disk cutter drawings to obtain different cutter ring structure types, and using cutter ring structure parameters including parameter radii, blade angles, blade width, transition arc radii, fit interference magnitude of a cutter ring and a cutter body, thickness of a sleeve between bearings and the like as design variables to establish a disk cutter CAD parameterized model base; selecting a typical stratum according to the different parameters of wall rock attributes, and establishing a mould satisfying geological adaptability and having different cutter specific energy consumption as an optimization objective; obtaining optimized disk cutter ring structure types and geometric parameter values through an SAGA algorithm; and obtaining the optimized fit interference magnitude of the cutter ring and the cutter body and the optimized thickness of the sleeve between the bearings through the obtained geometric modeling structure of the disk cutter ring by adopting a finite element analysis method. The invention improves the cutter adaptability for geology and provides a high efficiency platform for cutter design and manufacture.

Description

technical field

[0001] The invention relates to an optimization design method, in particular to a geological adaptability design method of a disc hob based on CAD / CAE and optimization design, and belongs to the technical field of underground space engineering excavation equipment. Background technique

[0002] The disc hob is the rock-breaking tool of the shield machine during the tunneling process, and its rock-breaking efficiency directly affects the tunneling speed and efficiency of the shield machine. The geological conditions of the shield machine during the excavation process are complex, and the physical parameters vary greatly in different strata, resulting in an increase in the random sudden change load borne by the disc hob. The knife ring is used as a disc hob to directly contact the rock mass for rock breaking The damage of the spare parts is quite large and the consumption is large. At the same time, due to the improper selection of the disc-shaped hob cutter r...
