Embodiment approach

[0014] see Figure 1-2 , the implementation method of the present invention is as follows:

[0015] Step 1: Establish a three-dimensional solid model of the four-point hydraulic support platform. Firstly, a precise four-point hydraulically supported platform is established in the professional 3D modeling software SolidWorks. Since the 3D drawing tools provided by ADAMS cannot meet the needs of drawing, as a preprocessor of modeling, a 3D solid model is established in SolidWorks. The three-dimensional solid model of the four-point hydraulic support platform is as follows: figure 1 As shown, it is composed of a platform 1 and four hydraulic outriggers 2, 3, 4, 5, and the inclination angle between the platform and the horizontal plane is controlled by the expansion and contraction of the four hydraulic outriggers 2, 3, 4, 5.

[0016] Step 2: Establish the dynamic mechanical model of the virtual prototype, import the 3D solid model established in the solid modeling software int...

Abstract

The invention discloses a co-simulation method of a levelling system of a hydraulic supporting platform based on a virtual prototype. The method comprises the following steps of: establishing a three-dimensional solid model of the hydraulic supporting platform in three-dimensional modelling software, and controlling an inclined angle between the platform and a horizontal plane by telescoping of hydraulic supporting legs; importing the three-dimensional solid model into mechanical system dynamic analysis software for analysis to form a dynamic mechanical model of the virtual prototype; establishing a system hydraulic loop on the dynamic mechanical model of the virtual prototype, and establishing a complete virtual prototype model; combining the virtual prototype model with a control system in mathematical laboratory software by a control system module of the mechanical system dynamic analysis software; and establishing a co-simulation control model. The test debugging process of a physical prototype is simplified greatly by combining a virtual prototype technology with a control system simulation technology, and the method can be popularized and applied to computer simulation of other complicated mechanical systems.
