With the in-depth study of mechanical transmission system dynamics, there are more and more kinds of software used for transmission system dynamics analysis. Mechanical system dynamics analysis software has its own characteristics and is different from each other. According to the characteristics and research object of the software, the dynamic simulation analysis and dynamic meshing process are studied by using RomaxDesigner software.
RomaxDesigner’s analysis of transmission system mainly includes the following two aspects:
1) Basic analysis of transmission system
(1) For parallel shaft transmission system: load spectrum analysis, static analysis and dynamic analysis of shaft, bearing and gear system are carried out to obtain the stress and strain of shaft and the natural and dynamic characteristics of gear pair;
(2) For vertical shaft transmission system: analyze the static and dynamic characteristics of shaft, bearing and gear system;
(3) For planetary gear transmission system: calculate the rated life of gear working cycle based on AGMA and ISO standards, and accurately analyze the factors affecting gear strength; Analyze the cycle power layout, static analysis and dynamic analysis;
2) Other advanced analysis and optimization functions
(1) Advanced bearing analysis: analyze the working performance of centripetal ball bearing and tapered roller bearing under complex working conditions, and quickly and accurately calculate the impression and contact stress of the rolling element running in the raceway; Allow users to customize the required bearings and bearing lubricants;
(2) Shaft fatigue analysis and Optimization: the ANSI method is used to automatically optimize some parameters of the shaft, and the fatigue analysis of the shaft is carried out based on the manually set stress concentration source and material fatigue properties;
(3) Geometric optimization of helical gear: according to the optimization variables and objectives, a variety of optimization methods are adopted to automatically optimize the geometric parameters related to the gear structure;
(4) Micro geometric optimization of gear: Micro modification of gear. The software has involute modification, diagonal modification and manual modification;
(5) Structural flexibility analysis: considering the influence of structural flexibility on system performance, for planetary carrier, box and other components, it is usually coupled with the transmission system with its finite element model;
(6) System dynamics analysis: system dynamics analysis; Simple shafting dynamics analysis; Flapping analysis; NVH analysis (system noise, vibration and harmonic response analysis).
