What technical requirements should be considered in steady-state design and dynamic design?

Technical requirements for steady-state design and dynamic design: Once the characteristics and parameters of each part of the main loop of the system are preliminarily determined, the mathematical model of the system can be established to prepare for the dynamic design of the system.

Steady-state design is a functional stability problem. It is usually because the components that make up the system are not considered to have tolerances, and their characteristics and parameters change with the change of environment. These changes make the products unable to meet the specified performance and technical requirements, and make the products unable to complete the specified functions. Robust design itself is a kind of reliability design technology for product functional stability.

Classification of steady-state design:

The methods of mechanical robust design can generally be divided into two categories: one is the traditional robust design method based on empirical or semi-empirical design, which mainly includes Taguchi robust design method, response surface method, double response surface method, generalized linear model method and so on. The other is the mechanical robust optimization design method based on mechanical engineering model and optimization technology, which mainly includes tolerance polyhedron method, sensitivity method, variable transfer method and stochastic model method.

Robust design includes product design and process design. Through robust design, the performance of the product can be unaffected by various noise factors and has strong anti-interference ability. The product performance is more stable and the quality is more reliable.
