Paper Title:
Fatigue Strength Analytical Study of Truck-Mounted Concrete Pump
  Abstract

This paper is based on the design of the boom system of concrete pump car.fatigue strength of the boom system is analysed detailedly after completing a series of work, such as the boom system simulation, static strength , the stability analysis and structural optimization. Analysis shows that the easiest damaged location of the boom system is in the joint of the third boom, that is the place of the maximum stress in static analysis of the boom system.The safety coefficient is 1.393 after finishing fatigue analysis,and the numerical value is still bigger than specified safety coefficient, namely 1.3;the minimum life total amount (cycle) is 323500, which occurs in the third quarter boom, that is the place of the maximum stress in static strength analysis of the boom system; the fatigue strength of the boom system satisfy the requirement.These research work provide reliable reference for the design and improvement of the boom structure.
