Abstract:

According to occurs fracturing phenomenon of the flameproof diesel engine support of the mining flameproof load-haul dumper (LHD) in underground coal mine, this article establish the modeling basing on the finite element analysis software ANSYS combination flameproof diesel engine support structure characteristics and load characteristic, obtaining the vibration modal chart and stress cloud chart of the flameproof diesel engine support on calculating the model. then according to the result optimizing and improvement the flameproof diesel engine support. But also for other similar transport equipment to solve the problem and improve the design of a useful reference.

Key words: the flameproof load-haul dumper, the flameproof diesel engine, modal, stress
