Coin circulation plays a fundamental role in daily consumption and commercial settlements across various civilian scenarios. Traditional coin weighing equipment development has heavily relied on physical prototypes for repeated calibration, suffering from chronic issues such as slow R&D progress, excessive testing costs, and limited adaptability to diverse operational environments, thereby failing to meet practical standards for multiple application scenarios. With practicalization of coin weighing devices as the core research focus, virtual simulation technology has been integrated throughout the development process. This approach establishes a comprehensive lifecycle design and validation framework, clearly defining the design logic, technical implementation methods, and deployment plans. Through virtual modeling combined with simulation testing and continuous iterative improvements, common defects in legacy equipment, including material jamming, measurement accuracy errors, and insufficient anti-counterfeiting recognition precision, have been effectively addressed. The overall structural design, operational functions, and performance of the equipment have undergone holistic enhancement and upgrading.
