Research on hilly mountain tractor based on adaptive

摘要

Finite element method is an effective numerical analysis method developed to adapt to the use of computer [1].Its role in engineering practice has been extended from analysis and verification to optimization design,and it has become a computer aided by computer aided design (CAD) Engineering (CAE) an important part.With the increasing complexity of engineering practice problems,the application of finite element method and error analysis method in one of the adaptive finite element method is becoming more and more popular.The adaptive finite element mesh which reflects the physical and geometric characteristics of the structure is the necessary part of applying the adaptive finite element method.With the trend of the development of tractors in the direction of intelligent,lightweight,the application of electronic technology and micro-control technology to tractors is an inevitable way.In this paper,based on the traditional tractor hydraulic suspension system,a tractor system with force adjustment function is designed.Compared with the traditional tractor hydraulic suspension system,the system uses the electronic control technology to realize the deep displacement adjustment and force regulation,control the chip acquisition force sensor and the position sensor real-time feedback signal to raise or lower the hanging rod.Introduction.
