Analysis and Optimization for Vibration Isolation Performance of a Hydraulic Excavator’s Powertrain Mounting System
摘要
Abstract
The mathematical model and the Adams dynamics model are established for the powertrain mounting system of a domestic hydraulic excavator. The simulation results show that there is a serious coupling phenomenon in the powertrain mounting system, and its vibration isolation performance is poor. Integrating Matlab with Isight software, an optimization model is constructed with the suspension stiffness parameters as the design variables and the energy decoupling as the objective function. Sensitivity analysis and optimization analysis are implemented with the constraints of rational allocation of natural frequencies. As a result, the decoupling situation of the system is significantly improved. This optimization method has valuable reference for real-vehicle optimization of the hydraulic excavator’s powertrain mounting system.关键词
