Embodiment 1
[0062] see Figure 1-7 , a dynamic modeling and simulation method of a bolter mining machine, comprising the following steps:
[0063] Step S1: Set a plurality of three-way acceleration measuring points on the bolter digging machine, and obtain the measured acceleration data of the measuring points; the number of measuring points in this embodiment is three, which are respectively set at the cutting boom, cutting Cutting reel racks and skids, such as Image 6 Measuring point 1, 2 and 3 are shown.
[0064] Step S2: Determine the load information of the cutting drum, and obtain the working load spectrum of the integrated bolter digging machine within one working cycle;
[0065] Step S3: Establish the multi-body dynamic model of the whole machine, combine the operating parameters and the working load spectrum as the excitation for dynamic simulation, and calibrate the measured acceleration data of the measuring point and the acceleration simulation data of the corresponding mea...
