小型破碎锤液压系统效率仿真与测试OA

The hydraulic breaker is a commonly used operating tool,which is installed on main machines such as excavators for crushing and demolition operations.To study the efficiency characteristics of the hydraulic system during the operation of the hydraulic breaker,modeling,simulation,and experimental testing are conducted on the hydraulic system of a small hydraulic breaker.Firstly,the working principle of the small hydraulic breaker is analyzed.Then,a model of the hydraulic breaker's system is established based on Simulink,and simulations are carried out.Through this,the pressure curve of the nitrogen chamber in the hydraulic breaker and the instantaneous efficiency curve of the system are obtained.In addition,experimental tests are performed on the operation of a mini-excavator with a small hydraulic breaker.The pressure signals of the nitrogen chamber of the breaker and the hydraulic system are collected,and the instantaneous efficiency and average efficiency of the breaker are derived.This research provides a reference for the study on the efficiency of hydraulic breaker system.
