The invention discloses a frame type undercarriage for a static test. The frame type undercarriage comprises an undercarriage body, two stable buffers and four hinge seats, the stable buffer comprises a buffer pipe, a first spring, a second spring, a balance column, a pull rod, a first hinge lug and a second hinge lug. According to the invention, the stability and precision of the frame type undercarriage in a static test can be obviously improved, the manufacturing, mounting and dismounting of the buffer become more convenient through the simplified structural design, and the labor intensity of operators is reduced. Meanwhile, a non-hydraulic element is adopted as a buffer core, so that the buffer is more reliable to use, performance fluctuation and maintenance difficulty possibly brought by the hydraulic element are avoided, and the efficiency and accuracy of the test process are improved.
本发明公开了一种车架式静力试验起落架,包含起落架本体、2个稳定缓冲器和4个铰接座;稳定缓冲器包含缓冲管、第一弹簧、第二弹簧、平衡柱、拉杆、第一铰耳和第二铰耳。本发明能够显著提升车架式起落架在静力试验中的稳定性和精度,简化的结构设计使得缓冲器的制造、安装与拆卸变得更加便捷,降低了操作人员的劳动强度。同时,采用非液压元件作为缓冲核心,使得缓冲器的使用更加可靠,避免了液压元件可能带来的性能波动和维护难度,从而提高了试验过程的效率和准确性。
