    • This disclosure includes methods for testing hydraulically-actuated devices and related systems. Some hydraulically-actuated devices have a housing defining an interior volume and a piston disposed within the interior volume and dividing the interior volume into a first chamber and a second chamber, where the piston is movable relative to the housing between a maximum first position and a maximum second position in response to pressure differentials between the first and second chambers. Some methods include: (1) moving the piston to the first position by varying pressure within at least one of the first and second chambers such that pressure within the second chamber is higher than pressure within the first chamber; and (2) while the piston remains in the first position: (a) reducing pressure within the second chamber and/or increasing pressure within the first chamber; and (b) increasing pressure within the second chamber and/or decreasing pressure within the first chamber.
    • 本公开包括用于测试液压致动装置和相关系统的方法。 一些液压致动装置具有限定内部容积的壳体和设置在内部容积内并将内部容积分成第一腔室和第二腔室的活塞,其中活塞可相对于壳体在最大第一位置和最大第一位置之间移动 响应于第一和第二腔室之间的压差的最大第二位置。 一些方法包括:(1)通过改变第一和第二腔室中的至少一个腔室内的压力使活塞移动到第一位置,使得第二腔室内的压力高于第一腔室内的压力; (2)当活塞保持在第一位置时:(a)减小第二室内的压力和/或增加第一室内的压力; 和(b)增加第二室内的压力和/或减小第一室内的压力。

    • A Shock Absorbing Horseshoe A shock absorbing horseshoe having a shock absorbing layer/zone of lattice form. The size of the walls and/or interstices of the lattice structure can be varied to vary the compressibility of the shock adsorbing layer. The shoe includes a relatively inflexible member that may be metallic. The inflexible member is arranged to sit nearest most the hoof. The shoe may also include a tread layer for contact with the ground, the tread layer and shock absorbing layer being formed from a single integral piece using a 3D printing process. The inflexible member may be formed of two parts positioned on either side of the frog and joined, and possibly inset within a relatively flexible material.
    • 减震马蹄具有减震层/格子形状区域的减震马蹄。 格子结构的壁和/或空隙的尺寸可以变化,以改变震动吸收层的可压缩性。 鞋包括可以是金属的相对非柔性构件。 柔性构件被布置成最靠近蹄最近坐。 鞋还可以包括用于与地面接触的胎面层,胎面层和减震层使用3D印刷工艺由单个整体件形成。 非柔性构件可以由位于青蛙两侧的两个部分形成并且可以嵌入相对柔性的材料中。
