SolidWorks Simulation design simulation makes Daxing Technology laugh
Daxing Technology (Shenzhen) Co., Ltd. has successfully implemented an optimized design approach for folding bicycles by leveraging SolidWorks design and simulation solutions. This case study highlights how the company, a global leader in folding bike manufacturing, enhanced its product development process through advanced digital tools.
Founded in California in 1982, the DAHONCALIFORNIA (INC.) Group pioneered the promotion of eco-friendly transportation, specifically folding bicycles. With well-known brands like DAHON and YEAH!, their products are sold worldwide and have earned numerous international accolades. The company has expanded globally, establishing branches and factories in mainland China, Taiwan, the Netherlands, and Macao. It is recognized by Guinness World Records as the "world's largest manufacturer of folding bicycles."
The company offers a wide range of folding bikes, including city, electric, mountain, and sports models, available in various frame sizes such as 12", 14", 16", 18", 20", 24", and 26". These designs emphasize ergonomics, comfort, speed, and ease of use. Daxing maintains strict quality control, adhering to international safety standards like EN, JIS, CPSC, DIN, BS, and AS to ensure consumer trust.
Despite its success, Daxing faced several challenges during product development. Exporting required compliance with different regional safety standards, while the complex frame structure made manual strength calculations difficult. Prototyping was time-consuming and costly, leading to long development cycles and high resource consumption. Rising material and labor costs also affected profitability, and engineers had to balance cost-effectiveness with safety.
To address these issues, Daxing adopted SimulationWorks, a powerful tool for structural analysis, vibration testing, reliability assessment, and optimization. By following EN standards, they conducted fatigue analysis on the frame under pedal force. Using SolidWorks models, they performed static analysis to evaluate stress, displacement, strain, and safety factors. The Gerber stress correction method was applied due to the plastic nature of the frame material.
Through simulation, Daxing identified areas for improvement, optimizing the frame to reduce weight from 3.35 kg to 2.48 kg, saving 26% in materials. Frequency analysis was used to prevent resonance, ensuring the frame’s durability. The results showed that simulation data closely matched test data, making it possible to replace some physical tests with virtual ones, reducing both time and cost.
Overall, the implementation of simulation-based design significantly improved Daxing’s R&D efficiency, reduced development time, and enhanced product performance. The company gained a competitive edge in the industry, with its new designs receiving strong market responses at major exhibitions in Europe, Japan, and Taiwan.
