The 3D modeling for weighing sensor is drawn. The stress distribution of the weighing sensor is analyzed. Mechanical calculation and finite element analysis for the coal mine hoisting pulley weighing sensor assembly is analyzed with the method of material mechanics and SolidWorks Simulation finite element analysis method. The analysis result proves that the strength of the selected sensors and the joint bolt satisfies the requirement of the strength of the coal mine main shaft lifting devices. Conclusion;（1）the allowable stress of the sensor in theory of 211.7 MPa, greater than the sensor actual stress of 6.180 MPa;（2）the biggest stress of sensor assembly is 130 MPa, the maximal displacement of sensor assembly is 0.005 06 mm, strain is 0.000 045 7, the data comply with the design requirements;（2）The finite element analysis method of Simulation is simple and easy to use,more close to actual working condition, very suitable for type selection design of electromechanical products.
