Reliability-based design optimization(RBDO)

Reliability measures generally have three types: reliability, failure-free rate, and failure rate. The study of reliability issues was developed during the Second World War to deal with the unreliability of electronic products. The research on reliability design used in machinery began in the 1960s and was first applied to military and aerospace industries, and then gradually expanded to civil industries.

Sources of mathematical reliability

Mathematics has existed and developed for thousands of years. He originated from practice, but also rooted in human reason. Mathematics has always been effective in the journey of human understanding of the world, and it must be effective in the future, because no learning is more rigorous, rational, and reliable than mathematics.

Important reasons for early die failure

In order to improve the plating efficiency, a negative voltage is generally applied to the workpiece.
The surface treatment technology of forging dies is not widely used in China, so it is necessary to develop in this field. Surface hardening support such as carburizing, nitriding, boronizing, carbonitriding of the whole mold cavity and local spraying, brush plating and surfacing of the mold cavity are very promising.

N95 semi-automatic rotary edge banding machine, model parameters can be edited, equipment drawings are a full set of drawings, including engineering drawings.

What is reliability design

“Reliability of products is designed, produced and managed”, but practice has proved that the reliability of products designed first. Reliability design has a significant impact on the inherent of the product.

Requirements for hygienic design

All materials and components used on the machine shall be compatible with the usual cleaning products used on these production lines.

Face mask ultrasonic welding principle

The principle is the use of sound waves reached the peak position of the gap between the plastic, in the case of pressure, so that the two fusible elements which could be part of the plastic parts in contact with each other to produce the high-speed friction melts, the contact surface of the plastic fusion, achieve the purpose of processing.

39 knowledge points of mechanical design

Failure modes of mechanical parts: overall fracture, excessive residual deformation, surface damage of parts (corrosion, wear and contact fatigue), failure caused by damage to normal working conditions.
