摘要： A crash can is made of aluminum-alloy casting and provided between a side frame extending in a vehicle longitudinal direction at a side portion of a vehicle and an end portion of a bumper reinforcement extending in a vehicle width direction. The crash can comprises a hollow tube portion extending in the vehicle longitudinal direction and having a cross-shaped section. At least one of an outwardly-projecting corner portion and an inwardly-projecting corner portion of the tube portion is formed by a groove such that a thickness thereof is thinner than that of the other portion of the tube portion. Accordingly, an impact which a vehicle body or a passenger may receive in a vehicle collision can be reduced by the crash can.
摘要翻译：碰撞罐由铝合金铸件制成，并且设置在车辆侧部沿车辆纵向方向延伸的侧框架和沿车宽方向延伸的保险杠加强件的端部。碰撞可以包括在车辆纵向方向上延伸并且具有十字形截面的中空管部分。管部的向外突出的角部和向内突出的角部中的至少一个由凹槽形成，使得其厚度比管部的另一部分的厚度薄。因此，可以通过碰撞罐减少车体或乘客在车辆碰撞中可能接收的冲击。

摘要： The joining method includes a step of lapping the aluminum alloy plate and the plated steel plate via adhesive, a pre-heating step of clamping both metal plates lapped in the lapping step between a pair of electrodes for spot welding and applying pressure thereto, and applying a current between the pair of electrodes, a cooling step of pressurizing both metal plates at a pressing force higher than that at the start of the pre-heating step in a state where conduction between the electrodes is stopped, and continuing this pressurization over a predetermined cooling time, and a welding step of pressurizing both metal plates at a pressing force higher than that at the start of the pre-heating step, and welding both of the metal plates by applying a current higher than the conduction current value in the pre-heating step between the pair of electrodes.

摘要： A main body of an impact energy absorber is formed by integrally molding a deformable portion and a plurality of deformation controlling portions which are adapted to control the direction of plastic deformation of the deformable portion. The deformation controlling portions have such a configuration and shape that, when a compression load equal to or greater than a predetermined value is input to the main body in a tube axis direction, the deformable portion undergoes plastic deformation in at least one of a radially outward direction and a radially inward direction of the main body concurrently with the compressive plastic deformation in the tube axis direction.

摘要： It is an object of the invention to provide high-ductility alloy which is improved both in casting characteristics and elongation without lowering strength by selecting a good combination of ingredients and a proportion thereof. It is another object of the invention to provide a casting which has an good elongation without being heat-treated. It is a further object of the invention to provide a method of manufacturing integral parts having some portions with specific construction which make it impossible for a set of molding dies to be separated after finishing casting by means of in-one-piece molding. Those objects can be accomplished bay providing an high ductility aluminum alloy which contains manganese ingredient, iron ingredient, magnesium ingredient and slice of unavoidable impurity, wherein a content of the iron usually regarded as impurity is set within specified limits, magnesium content is relatively less and manganese content is relatively more than that in a conventional aluminum alloy. More specifically the high ductility Al alloy contains 1.0-2.0% by weight manganese, 0.4-1.5 & % by weight iron, 0.91-0.5% bit weight magnesium and the balance of aluminum and impurities.
