The three-dimensional modeling of the load cell was carried out. The force condition of the load cell was analyzed. The mechanical calculation and finite element analysis of the load cell assembly of the coal mine hoist using the method of material mechanics and the finite element method of SolidWorks Simulation were performed. The selected sensor and bolt strength to meet the strength of the mine shaft hoist equipment requirements. The conclusions are drawn as follows: (1) The theoretical allowable stress of the sensor is 211.7 MPa, much larger than the actual stress of the sensor of 6.180 MPa; (2) The maximum stress of the sensor assembly is 130 MPa, the maximum displacement is 0.005 06 mm and the strain is 0.000 045 7 , Meet the design requirements; (3) Simulation finite element analysis method is simple and easy to use, more close to the actual conditions, it is suitable for mechanical and electrical product selection design.
