Bearings are critical components in a wide range of mechanical systems, and their performance directly affects the efficiency, reliability, and lifespan of the equipment they support. In recent years, the development of simulation technologies has revolutionized how engineers analyze and predict bearing behavior under various operating conditions. Simulation skills in the field of bearings involve using advanced computer models to replicate real-world scenarios. Engineers input key parameters such as load direction, magnitude, rotational speed, and environmental conditions into the software. The system then performs complex calculations to estimate the bearing’s expected service life and evaluate its suitability for specific applications. This approach significantly reduces the need for physical testing, saving time, resources, and costs while allowing early-stage predictions about performance. Leading global manufacturers like SKF and NTN have made significant strides in this area, integrating simulation techniques into their product development cycles. These companies use simulation not only to improve design accuracy but also to accelerate the innovation process. However, despite these advancements, practical application of simulation remains limited in many regions, especially in developing markets. In China, the focus on simulation experiments has been concentrated on high-priority areas such as railway vehicle bearings, automotive wheel bearings, and high-speed grinding spindles. While there are several research institutes and state-owned enterprises capable of conducting simulation tests, the overall scale and depth of these experiments are still expanding. Institutions like the Luoyang Bearing Research Institute, Haishan Institute, and the Hangzhou Bearing Experiment Center play a crucial role in this domain. The methods used for bearing simulation vary globally. Common approaches include tribological wear testing, bench testing, and laboratory simulations. Each method serves different purposes depending on the stage of product development. For example, new products often require extensive tribological testing before moving to more refined simulation or bench trials. In contrast, if the operational conditions change slightly, simplified tests may be sufficient. Foreign companies, particularly in Europe and Japan, tend to apply rigorous real-world testing for critical components like car wheel bearings. These tests ensure that products meet strict quality and safety standards before being released to the market. While simulation can reduce the need for physical testing, it is not yet fully replacing traditional methods in all cases. In China, the adoption of simulation experiments is growing, but there is still room for improvement. More investment in both hardware and software infrastructure is needed to support large-scale simulation studies. Additionally, expanding the scope of testing to cover a wider range of working conditions will help improve the accuracy and applicability of simulation results. As the industry continues to evolve, the integration of simulation technology with real-world data will become even more important. This synergy will enable engineers to make better-informed decisions, enhance product performance, and ultimately drive innovation in the bearing sector.
