In this paper, the reliability of the loader system is modeled, and the reliability of the loader system is analyzed based on the parameters of the loader system. On this basis, the reliability distribution of loader system is completed. Based on the system reliability allocation criterion, the reliability allocation data of the series model between each subsystem of the loader is calculated. The reliability distribution model will help to solve the problems of short service life and poor operation reliability of wheel loaders developed and produced by our country at present. It will provide a useful reference for the design and optimization of loader system.
Based on ABAQUS platform, this paper completes the simulation of micro-aluminum wire straightening process. Through ABAQUS simulation analysis software, combined with the characteristics of straightening process in metal wire, the straightening process is simulated and simulated; This paper analyzes some state parameters (plastic strain, residual stress, straightening force and straightness, etc.) of metal wire after straightening, and verifies the correctness of structural parameters, technological parameters and straightening scheme design included in straightening device by comparing the change curves of coordinates before and after straightening; It provides a reference basis for further perfecting the straightening theory of ultra-fine metal wire and exploring how to improve the configuration of related parameters in the straightening process.
This paper evaluates the stability of loaders based on stability. The shortcomings of the evaluation method based on stability ratio are analyzed. The longitudinal stability, lateral stability, longitudinal stability and lateral stability of articulated loader on the ramp when the loader does not steer are analyzed and calculated in detail; A new idea is put forward for the research and calculation of loader stability.
