Embodiment Construction

[0035] 1. CAE modeling

[0036] Based on the parametric design language, a CAE analysis-oriented parametric modeling system for the multi-stage gear mechanism of a typical mining reducer is developed to realize the parametric modeling and automatic assembly of cylindrical gears, planetary gears, and spur bevel gears. The established overall parameterized model can not only be used for CAE simulation analysis under finite element, but also can be exported to other simulation invention patents for joint simulation. Parametric design language, which provides functions of general programming language, such as parameters, macros, scalars, vector and matrix operations, branches, loops, repetitions, and access to finite element databases. Using its parametric design language in finite element, the parametric modeling of involute spur gears can be realized through variable parameters, array parameters, mathematical expressions and functions, macro files and user programs. Realize the...

Abstract

The invention belongs to the technical field of gear detection and measurement, in particular relates to a gear load wireless monitoring system and an interactive multi-stage gear physical simulation method finished based on the same. The invention overcomes the defects and limitations of the existing gear monitoring and simulation method. The gear load wireless monitoring system comprises an upper computer and a lower computer, wherein the lower computer is internally arranged on a measured gear structure, and the lower computer with a wireless transmission function is in wireless transmission with the upper computer. The interactive multi-stage gear physical simulation method comprises the following steps of: detecting an external field; carrying out gear solid modeling, and carrying out grid partition on the gear solid model by adopting swept mapping; setting boundary conditions; carrying out finite element analysis; and verifying the data subjected to finite element analysis and actual measurement. According to the invention, wireless data transmission and load identification testing schemes are used for correcting the error of CAE (Computer Aided Engineering) analysis so as to master the stress rule of the gear, thereby providing a basis for fatigue life prediction. The system and method provided by the invention have higher practical and economic values.

Description

technical field [0001] The invention belongs to the technical field of gear detection and measurement, and in particular relates to a gear load wireless monitoring system and an interactive multi-stage gear physical simulation method based on the system. Background technique [0002] As an important transmission mode, gear transmission has a wide range of applications in the mechanical field. [0003] The machinery manufacturing industry is facing unprecedented development opportunities, and high speed and heavy loads have become one of the development directions of gear transmissions. However, under the condition of high speed and heavy load, due to the long-term repeated action of the cyclic load on the working face of the gear teeth, it is very easy to cause failures such as fatigue, cracks, erosion, indentation, etc., which will cause gears such as fracture, sticking, burning, etc. These faults will reduce the rotation accuracy of the gear, generate vibration and noise,...
