The Mechanical Excavator - Hydraulic System of the Establishment of Co-Simulation and Optimization

Abstract

By using UG and ADAMS software, the mechanical system and hydraulic system model of excavator working device are established. Moreover, together with the application of the parameters of the ADAMS associated technology, the virtual prototyping model of mechanical excavator and hydraulic integration are established; These two software also work on the motion simulation, as well as the optimization analysis of the main components of the system. This parameter association technology research method is characterized by a comprehensive analysis both of the dynamic and static situations. The results provide some reference value for the feasibility of the design and the manufacture of the virtual samples. Meanwhile, it provides some theoretical and engineering significance.

Using wavelet denoising in automatic online efficiency estimation of a hydraulic excavator

“…Currently, computer-based performance detection systems have been widely used in the automobile industry for online detection and estimation of transmission systems (Bumby and Masding, 1988), braking performance (Chen and , energy consumption (Wu et al, 2009) and noise (Liu et al, 2013;Wang DP et al, 2014;Wang GT et al, 2014), with improved detection efficiency and accuracy, as well as providing data support and guidance services for the optimization of product design. They have also been used in measurement and analysis of hydraulic excavators, mainly focusing on fault diagnosis (Ni et al, 2013), auxiliary safe driving (Sun and Zhu, 2013;Winck et al, 2015;Yoshinada et al, 2012), digging trajectory optimization (Predrag et al, 2011) and optimizing core components (Jiang and Jiang, 2012), thus improving the reliability, safety and performance of excavators.…”
