Abstract

For the sake of analyze the dynamic characteristics of the working device of the hydraulic excavator, a three-dimensional model of the working device of a certain type of hydraulic excavator is established, and its four typical working conditions are determined. The finite element model of the working device is established, and the first six natural frequencies and main modal forms of the working device of the hydraulic excavator under four working conditions are calculated, which provides a basis for optimizing the dynamic characteristics of the working device of the hydraulic excavator.
