Ergonomic dynamic design method based on chaotic recognition

Abstract

The invention belongs to the field of engineering machinery, and particularly relates to an ergonomic dynamic design method based on chaotic recognition. The method adopting the technical scheme can be used in the fields of the design of various kinds of machinery with the ergonomic design requirements, such as road roller. According to the technical scheme, on the basis of building a dynamic model, the aspects such as the weight of a mechanical equipment machine frame structure to be designed, the rigidity coefficient of a mechanical vibration reducing system and the damping coefficient are subjected to dynamic design through avoiding the chaotic state response due to non-linear vibration of the machine frame system, further, from the driving comfort aspect of a driver in the ergonomics, the non-linear chaotic vibration phenomenon of the system is avoided under the condition that the whole machine of mechanical equipment meets the movable and static loads, the driving comfort is improved, and the service life of each mechanical equipment vibration structural element is prolonged.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to a dynamic design method of man-machine engineering based on chaos recognition. Background technique [0002] In the existing field of mechanical design, it is usually the static design of each component of mechanical equipment. Even if there is a dynamic design, it is a relatively simple dynamic design. The mechanical structures in the aforementioned existing designs, especially the static or simple dynamic design methods of mechanical structures involving human-computer interaction, have at least the following defects: [0003] (1) Static design only considers static analysis, which is too simple to be suitable for applications in fields such as vibration utilization engineering and construction machinery vibration. [0004] (2) The simple dynamic design only considers the impact of mechanism or environmental vibration on the structural damage of the machinery ...

Problems solved by technology

[0003] (1) Static design only considers static analysis, which is too simple to be suitable for applications in vibration utilization engineering, construction machinery vibration and other fields

[0004] (2) The simple dynamic design only considers the impact of mechanism or environmental vibration on the structural damage of the machinery (machine) itself, and seldom considers the impact of mechanical vibration on the physical and mental health of the driving operator, such as the huge impact of vibration on the operator's heart and bones, as well as the impact of the loud noise generated by nonlinear vibration on the operator's hearing, which is likely to cause serious occupational diseases and easily cause psychological irritability for the driving operator
