Abstract: Measurement fixtures serve as the core tooling for component inspection in vehicle manufacturer model projects. Regarding the two mainstream types of measurement fixtures on the market (integrated measurement fixtures and flexible measurement fixtures), the selection directly affects the project's upfront costs and the hoisting efficiency of measurement fixtures during the inspection process. Currently, the industry faces a core contradiction in measurement fixture selection among cost, efficiency, and accuracy. Meanwhile, with the accelerating iteration of new vehicle models and the widespread adoption of platform-based production in the automotive industry, vehicle manufacturers urgently need a measurement fixture planning solution that balances cost control, inspection accuracy, and hoisting efficiency. Through three years of practical exploration across two new model projects at the Yancheng Branch of China FAW Group Company Limited, this paper addresses pain points of lower-cost flexible measurement fixtures, such as low calibration efficiency, poor stability during inspection, and installation errors. A measurement fixture planning model combining integrated and flexible fixtures has been developed. This model reduces the investment cost of project measurement fixtures while improving hoisting efficiency, all while ensuring measurement accuracy. Experimental verification shows that this planning model can reduce measurement fixture investment costs by 34% to 42% and improve hoisting efficiency by 23% to 32% under the premise of ensuring measurement accuracy. This study provides a theoretical reference and a practical model for measurement fixture planning in new model projects.
