introduction
Digital simulation tests are widely used in all aspects of the life cycle of household and similar electrical appliances.
The simulation, prediction, optimization and control of the process can improve the test efficiency, enhance the design quality of the product, reduce the development cost and shorten the product development cycle.
At the same time, digital simulation test is also an important part of digital twin. Digital twin is a specific target with data connection
The digital expression of the entity, the data connection can ensure the synchronization between the physical state and the virtual state at an appropriate rate and accuracy, in the home appliance
The industry will have broad application prospects. Digital simulation provides data support for digital twins and is the foundation and key technology for realizing digital twins.
In the face of the widespread application and technical support needs of digital simulation testing in the home appliance industry, the digital simulation standardization work
It is particularly important to do.
GB/T 45990 "Digital Simulation Test for Household and Similar Electrical Appliances" aims to guide home appliance companies to build digital simulation test platforms.
The platform can be used to carry out digital simulation tests, thereby reducing the investment in physical prototypes, reducing R&D costs, and quickly evaluating the optimization space of product performance.
time, accelerate the iteration of the product's entire life cycle, and improve the company's market competitiveness.
