Product 1
Development technology/material/manufacturing process nameGear flank twist prediction and micro-geometry optimization based on virtual manufacturing simulation
Innovation Highlights ? The gear virtual manufacturing simulation function can predict the influence of manufacturing deviation on actual tooth surface parameters in the design stage, such as the distortion effect generated during gear grinding, obtain key indicators such as contact spot and transmission error based on virtual manufacturing parameters, and predict the actual working performance of the gear at the design stage, such as fatigue durability, NVH, transmission efficiency and other key indicators. To make the right engineering decisions earlier.
? Estimates gear tool parameters for finishing manufacturing based on the macro and micro geometric parameters of the gear design. Expert users can also manually define grinding process parameters to evaluate the rationality and manufacturability of the micro modification design of the gear.
? When using a finishing machine with precise control of the distortion, the tooth surface distortion can be used as an effective micro gear modification method to improve the NVH performance of the drive system.

Product 1
Development technology/material/manufacturing process nameNVH performance development process for EV gearboxes considering tolerance sensitivity
Innovation Highlights The NVH performance of an electric gearbox is intricately linked to numerous parameters and tolerances of various components, including gears and bearings. The typical NVH design and development process for an electric drive gearbox involves the consideration of almost 60 design variables related to manufacturing tolerances, such as gear surface micro-finishing, misalignment, bearing bore concentricity, and preload. Additionally, it entails evaluating different combinations of tolerances in actual products. This approach utilizes the genetic algorithm and Monte Carlo random method integrated into the Romax software to simulate tolerance combinations in actual products, enabling swift optimization across a large sample size. It leverages statistical probability methods and engineering expertise to identify tolerance combinations for design variables that meet NVH performance requirements. This ensures that the resulting gearbox product exhibits outstanding NVH performance during mass production, facilitating a positive NVH performance development flow for electric drive products while ensuring robust product performance.
