    摘要: Devices, systems, and methods for modular molding of wind turbine blades are provided. Methods of molding wind turbine blades using a modular molding assembly or system and methods of substituting molds are provided. In some embodiments, a modular assembly includes a first base frame and a second base frame hingedly coupled to one another, a first tooling frame disposed on the first base frame, a second tooling frame disposed on the second base frame, a first shell mold coupled to the first tooling frame, and a second shell mold coupled to the second tooling frame. The first shell mold has a first mold surface and a first perimeter and the second shell mold has a second mold surface and a second perimeter. When in an open configuration, the first base frame is coplanar with the second base frame, and, in a closed configuration, the first perimeter contacts the second perimeter.

    摘要: A battery enclosure for a vehicle chassis having a base member with raised surface features on the upper surface outlining individual cells, each cell configured to receive at least one battery; a cover member having a plurality of depending surface features on the lower surface which are aligned with the surface features of the base member. The cover member includes a channel formed in the upper surface thereof, aligned with and extending along a length of the depending surface feature disposed on the bottom surface. A lattice support structure is also included which has a plurality of support members extending axially and transversely, wherein the lattice support structure is configured to be at least partially disposed within the channel of the cover member and mounted to the vehicle chassis. The lattice support member providing increased rigidity and a load distribution path for externally applied forces (e.g. crash events) to prevent or inhibit enclosure breakage or puncture.

    摘要: Provided herein is a wind turbine blade mold system having built in precision pins to locate structural components (e.g. spar caps) during layup of composite segments. A plurality of pins can be inserted into apertures within the mold, with discs attached to the pins to maintain fixed relative distance to spar caps positioned relative to the pins to ensure precise positioning, thereby preventing/inhibiting movement of the spar cap relative to the mold. The pins can include a first extension that pierce through the layers of composite layups, and protrude above the B-surface of the blade skin. Additionally, the pins can include a marker tip releasably attached to the pin top to provide visual identification of the pin and underlying structural components. The pins can remain embedded within the final molded part.

    摘要: A mold for forming a flange of a wind turbine blade comprising a first flange portion including a plurality of lamina and having a generally planar shape and a second perpendicular flange including a plurality of lamina. A plurality of copper wires are disposed within the lamina for conducting heat delivered from a base portion through the first and second flange portions. The mold is free of fluid conduits with the flange portions moveable relative to the base portion.
