The invention discloses an automatic adjusting portal frame for a body-in-white modal test and an adjusting method. The two movable cross beams are symmetrically and longitudinally connected to the frame in a sliding mode, and the four electric hoists are symmetrically and transversely connected to the movable cross beams in a sliding mode. The displacement sensor is used for measuring the longitudinal movement distance of the movable cross beam on the frame; the electric hoist displacement sensor is used for measuring the transverse movement distance of the electric hoist on the movable cross beam; the height sensor is used for measuring the height of the electric hoist; and the control module is used for determining the height of the hoisted body in white according to the longitudinal movement distance of the movable cross beam on the frame, the transverse movement distance of the electric hoist on the movable cross beam and the height of the electric hoist. The method is wide in application range and suitable for white vehicle bodies of different sizes and different structures. The operation is simple, the portal frame can be simply, conveniently and automatically lifted, the safety risk in the test process is reduced, and the test efficiency is improved.

    本发明公开了一种用于白车身模态测试的自动调节龙门架及调节方法。它包括框架、两根对称纵向滑动连接于框架上的可移动横梁和四个对称横向滑动连接于可移动横梁上的电葫芦;还包括位移传感器,用于测量可移动横梁在框架上的纵向移动距离;电葫芦位移传感器,用于测量电葫芦在可移动横梁上的横向移动距离;高度传感器,用于测量电葫芦的高度;控制模块,用于根据可移动横梁在框架上的纵向移动距离、电葫芦在可移动横梁上的横向移动距离和电葫芦的高度来确定起吊白车身的高度。本发明适用范围广,适用于不同尺寸、不同结构的白车身。本发明操作简单,龙门架可简单方便的自动起吊,降低试验过程中的安全风险,提高试验效率。
