This paper focuses on the special working condition-accidental loss of the effective load of sub-boom working conditions for combined lattice boom, establishes a rigid-flexible coupled model of the sub-boom system based on ANSYS and ADAMS, and applies multi-body dynamics analysis method to conduct theoretical...

Aiming at the stability problem of crane lattice boom with large slenderness ratio, the applicability and practicability of four kinds of design theories and methods (the allowable stress method based on linear theory, the allowable stress method based on nonlinear theory, the limit state method based...

For a micro partial admission impulse turbine design, the present study analyzed the variable working conditions by numerical methods. The results indicate that the impact loss on the blade cascades will increase under off-design rotational speeds; the influence of admission fraction on the inner efficiency...
