Abstract
A convenient and feasible load collection technology for 5 ton loader working device is proposed in this paper. Based on the force characteristics of the working device and mechanics theory, the theoretical calculation model of external load is established. Firstly, the static load test shows that the relative error of the load value between the theoretical calculation and the actual apply is less than 5%. Then, the loader is subjected to the dynamic load test under a typical clay material. The external load values are obtained based on the theoretical calculation model and Adams dynamic simulation. The results show that the external load values between calculation and the simulation are basically the same. This proves that the load collection system is credible, which can provide the basic data for the structural design and the bench test and the fatigue analysis of the loader working device.
