Organic-inorganic composite solid electrolyte, preparation method and application of electrolyte in solid lithium battery

The invention discloses an organic-inorganic composite solid electrolyte. The solid electrolyte is characterized by being prepared from an acrylate material, lithium salt, a crosslinking agent, an initiator, a plasticizer, a fast ionic conductor and a porous rigid support material. The preparation method of the inorganic composite solid electrolyte is characterized by comprising steps as follows:mixing the acrylate material with the lithium salt to completely dissolve the lithium salt in acrylate; adding the crosslinking agent and the plasticizer to the mixed solution, and stirring the mixture evenly; adding the fast ionic conductor to the mixed solution, and performing ultrasonic treatment or stirring to disperse the conductor uniformly; adding the initiator to the mixed solution, and performing stirring uniformly; uniformly pouring the mixed solution on the porous rigid support material; performing heating initiation at 60-100 DEG C to enable the acrylate material to be copolymerized with the crosslinking agent to obtain the organic-inorganic composite solid electrolyte. The solid electrolyte has the advantages that the preparation method is simple, the production efficiency ishigh, and the assembled solid lithium battery has lower impedance and higher capacity.

Integral forming method of weldless axle housing of heavy truck

ActiveCN103252404AReasonable distribution of wall thicknessIncreased strength and rigidityHousing FirstTruck
The invention discloses an integral forming method of a weldless axle housing of a heavy truck. According to the method, reversed central spindle necking is carried out on two sides of the axle housing first, then hydro-bugling is carried out on the middle of the axle housing to obtain a bulging tube blank with sizes of two sides of the axis different, and then necking is carried out on two ends of the axle housing to obtain a preformed tube blank; ends of the preformed tube blank are sealed by a left pressure head and a right pressure head of a die and liquid is filled in the axle housing on a four-way hydraulic machine, integral press-forming is carried out on the preformed tube blank from the upper side, the lower side, the front side and the back side through an upper module, a lower module, a front module and a back module to obtain an axle housing tube fitting, a hemispherical rear oil cap is arranged on the rear side of an axle package part, and the front side of the axle package part is a plane; a round hole is punched in the front side of the axle package, the rear oil cap is reshaped with a stamping die, and then an axle housing workpiece is obtained. The heavy truck axle housing manufactured with the method is weldless, high in strength and rigidity, high in shape accuracy, good in wall thickness distribution, and low in manufacturing cost. Compared with a traditional hydro-bugling technique, the method has the advantages that liquid pressure needed in a manufacturing process is reduced by more than 60% and the tonnage of forming equipment is reduced by more than 50%.

Continuous variable cross-section car front longitudinal beam and preparation method thereof

ActiveCN103600773AHigh impact energy absorption performanceIncreased Strength and RigidityUnderstructuresEnergy absorbingEngineering
The invention provides a car front longitudinal beam structure and a preparation method thereof. The front longitudinal beam is of a hollow type cavity structure which is formed by connecting an inner plate with an outer plate along a longitudinal extension direction, and comprises an energy absorption region located at the front part of the front longitudinal beam, a support region located at the rear part of the front longitudinal beam and a transition region for connecting the energy absorption region with the support region, wherein a plate material in the energy absorption region is thinner than a plate material in the support region, and the plate material in the transition region is continuously and uniformly transitioned from the energy absorption region to the support region. The inner plate and the outer plate are connected through the adoption of a technology of combining laser welding, spot welding and cementation, so that the front longitudinal beam preparation technology is simple; the transition region of the inner and outer plates is continuously and smoothly connected with the relatively thin energy absorption region and the relatively thick support region, so that difference of front and back performances of the front longitudinal beam is realized, light weight and relatively high collision and energy absorption effects are guaranteed; energy absorbing ribs are arranged uniformly on each surface of the inner and outer plates, so that the car front longitudinal beam structure further improves collision energy absorption and is conductive to further improving car safety performance.

Foundation treatment method adopting water penetration pile in combination with vacuum preloading

ActiveCN103628468AAccelerates soil consolidation and settlementIncreased Strength and RigiditySoil preservationPile capStructural engineering
The invention discloses a foundation treatment method adopting a water penetration pile in combination with vacuum preloading. The foundation treatment method comprises the following steps: (1) fabricating the water penetration pile, wherein a pile body of the water penetration pile is a hollow tubular pile and provided with a pile cap; (2) blocking a treatment area of a foundation, forming a zone with a plurality of adjacent single blocks, carrying out synchronous construction on all the blocks during vacuum preloading, and carrying out a flow process between the zones; (3) driving the prefabricated water penetration pile in the foundation in a preloading zone, and fully spreading a sand cushion in a preloading area; (4) laying a vacuum pipe network; (5) paving a sealing film on the surface of the flattened sand cushion for a plurality of times; (6) digging out a seal trench in the periphery of an reinforcement zone, and vertically inserting the edge of the sealing film into weak soil along the inner wall of the seal trench and paving the film at the bottom of the trench flatly; and (7) carrying out vacuumizing and tightening the pile cap. As the water penetration pile is high in rigidity and strength, and good in water penetration performance, the pore water pressure and the settlement respectively accumulated in the foundation treatment process are low, and correspondingly, the post-construction settlement of the foundation is reduced; the bearing strength of the foundation is also improved.
