Dispersive characteristics and longitudinal resonance properties of trapezoidal corrugation coaxial slow-wave structure
A finite element study on influence of the sleeper support stiffness and damping on wear-type rail corrugation
Avoiding the friction self-excited vibration of wheelsets, Particularly relaxation vibration of wheelsets is the basic means for avoiding the rail corrugation.
Small performance hall: the whole performance platform is nearly surrounded by audience. The irregular corrugation of inside wall prevents the focus of sound wave. Audience will share the common space.
Bubble water is too long, skin absorbed moisture and expand, change so corrugation knits.
The utility model is favorable for the drying of the clothing in the dryer without corrugation, and the available space is large.
technology of manufacturing corrugation forming machine
The experiments showthat the corrugation can be dispelled after the process of shaping,when the cone explosive charge is used.
Process model of arc corrugation on friction-stir weld
The most effective way to reduce creepage and to inhibit the formation of such noise-initiating corrugation is through improved control of wheel and rail profiles.
After forming, the lining, film and the upper can closely joint, with our corrugation, and sparging.
Bragg structure is usually a kind of periodic structure with continuous corrugation phase, which has excellent mode selectivity and frequency selectivity properties.
