Since the current virtual simulation experimental platform is difficult to meet the needs of actual mechanical design, a virtual simulation experimental platform for elevator mechanical design based on Unity3D is studied. In the design of platform hardware, the overall structure of the platform is established, and the functional modules of the platform are formed according to the requirements of elevator mechanical design. In the platform software design, through the elevator mechanical design decomposition, the elevator mechanical structure is split, and the two-dimensional engineering drawing data is generated. Build a three-dimensional model of elevator machinery, build a virtual scene of three-dimensional simulation, and realize the assembly of elevator models. Based on Unity3D model import and data conversion, add texture material information, complete model rendering and processing. After experimental demonstration and analysis, the signal response values of the platform in this paper are all between ±1, which meets the application requirements of the platform. After the adjustment of the stiffness parameters of the car top spring is completed through the platform in this paper, the vibration frequency of the elevator is effectively improved, and it has a better effect on the vibration reduction of the elevator good support.
