Single bucket hydraulic excavator structure and designPublishing time: 2011 edition Brief introduction "Single bucket hydraulic excavator structure and design" introduces the development history, technology status and development trend of hydraulic excavators, the structural characteristics of single bucket hydraulic excavators, The working principle and hydraulic system are fully explained and introduced in detail. The use of vector mechanics and matrix methods focuses on the geometric motion relationship of the backhoe working device of the single bucket hydraulic excavator, the design method of the working device, the drawing of the digging envelope diagram, the calculation of the digging force of the whole machine, the stability analysis of the whole machine, and the component acceptance The force analysis and strength analysis are explained, and the corresponding analysis calculation formulas are deduced. These formulas are more suitable for computer programming operations. Based on this, the example model was analyzed in detail with the help of the excavator analysis software "EXCA" independently developed. Finally, the test specifications, test contents and test methods of hydraulic excavators in international and national standards were introduced in detail. "Single Bucket Hydraulic Excavator Structure and Design" is intended for senior students, graduate students and related engineering and technical personnel in the field of engineering machinery. It aims to help these people understand and master the structural characteristics, working principles, design theory and Methods and analytical research methods.
