    Abstract: The present invention relates to a two-phase, two-column linear pulse motor propulsion system, and more particularly to a two-phase, two-column linear pulse motor propulsion system which can implement high-speed driving, stopping, and switching directions forward/backward through non-adhesive driving characteristics by improving accelerating performance and torque performance.The two-phase, two-column linear pulse motor propulsion system comprises a field unit 121, 122 prepared in two columns in the longitudinal direction under a moving body 110 so as to generate a magnetic field; an armature unit 131, 132 which is prepared on a travelling track, generates a shifting field by the power supplied from a power conversion device, is prepared in two columns so as to correspond to the two-column field unit 121, 122 and generates the propulsion force of the moving body 110 through interaction due to a two-phase synchronous signal. Thus, it can improve propulsion force and acceleration/deceleration performance, compared to a linear propulsion system with one phase.

    Abstract: A sliding-type apparatus for absorbing front shock energy is disclosed. The sliding-type apparatus of the present invention includes a driver panel (130), which is provided on the front surface of a driver's cab defined by a front part protective shell (110) of a railway vehicle so as to be movable backwards, and a bottom shock absorber (150), which is provided under the lower surface of the driver panel (130). The sliding-type apparatus further includes a front shock absorber (170), which is provided on the front surface of the driver panel (130), and a driver panel shock absorber (190), which is provided at a position towards which the driver panel is moved backwards. Thus, when a railway vehicle is involved in a collision, the several shock absorbers are consecutively collapsed to efficiently absorb shock energy. Furthermore, the driver panel is moved backwards without being deformed by the shock energy. Therefore, the safety of the driver is ensured.

    Abstract: The present invention provides a gate drive for protecting a switching element (IGBT) used for an electrical inertial load controller. A high-voltage IGBT is used as the switching element and an hcp1316j is used as the gate drive of the IGBT, to restrict overvoltage and overcurrent generated in the event of inverter switching, preventing destruction of the IGBT in advance. Furthermore, an RC filter is formed in close proximity to the IGBT to minimize an erroneous switching operation due to harmonics generated caused by noise in case of inverter switching to improve the system reliability and block an increase in abnormal voltage applied across the switching element.

    Abstract: Disclosed are a prefabricated wire mesh assembly for a ballast and a method of constructing a gravel-ballasted track using the same. When a gravel ballast is used by filling a box-shaped rebar mesh with crushed stones and injecting a filling material, the prefabricated wire mesh assembly increases injection efficiency by further installing an internal partition wall to effectively support loads without forming a separate ballast shoulder and injecting a filling material through injection pipes installed on an internal partition wall, and prevents water accumulation on a roadbed by a drainage pipe. The prefabricated wire mesh assembly for a ballast is assembled by installing the injection pipe along with the lower mesh and the internal partition wall, thereby allowing the filling material to be injected without installation of a plurality of separate injection pipes, and securing construction quality by increasing injection efficiency of the filling material through the installed injection pipes.

    Abstract: Proposed is an anti-vibration pallet. More particularly, the present disclosure relates to an anti-vibration pallet that is capable of realizing an effect of an air spring by using only a combination of an auxiliary mount and a main mount that are formed of elastic bodies provided between an upper plate and a lower plate, and is also capable of maximizing an anti-vibration performance by controlling an optimal anti-vibration load according to a cargo load. In order to achieve the objectives described above, the present disclosure includes: an upper plate on which cargo is loaded on a top portion thereof; a lower plate positioned below the upper plate; a main mount installed between the lower plate and the upper plate; and an auxiliary mount installed outside the main mount.
