Modal Analysis of Concrete Pump Truck Boom

Abstract:

Boom is one of key components of concrete pump trucks which can be looked as a projecting beam when unfolded at pumping mode. Under different concrete pumping modes, vibration of boom is serious for the hydraulic cylinder switching over shock, which can lead to the early damage of boom structure. In the finite element analysis software, boom of 37 meters concrete pump truck is simulated for its modal. Natural frequencies and corresponding modes are got and analyzed. To reduce vibration of concrete pump trucks, advices are presented by finite element modal analysis.
