Abstract: The present invention belongs to the technical field of bridge wind tunnel test devices, and provides a free-vibration testing device for simulating nonlinear stiffness of a bridge rigid model. By flexibly designing the shape and the size of the rigid arc-shaped supporting arms, the spatial positions of the fixed bearing pulleys, the initial strains of the springs, and other parameters, this device can achieve multiple vertical-torsional coupled nonlinear stiffness modes, and also can achieve nonlinear stiffness only in the vertical direction while maintaining constant torsional stiffness, so as to carry out large-amplitude vertical-torsional coupled flutter and large-amplitude vertical galloping measurement tests under the nonlinear stiffness of bridge structures. During the large-amplitude vibration process of the model, the springs can always remain in a vertical state and will not experience lateral vibration, ensuring that the testing device has stable low damping, mass, and stiffness.

Abstract: Disclosed is a window shade with a balancing drive system including a base, a power assembly, an adjusting assembly, and a friction member. The poser assembly includes a coil spring. The adjusting assembly includes two reels and a transmission cord connected therebetween. One of the base and a first reel of the reels is fixedly connected to the bracket, and the other can be driven by the roller to rotate. When an extendable component connected to the roller is operated to be wound or unwound, a relative rotation between the base and the receiving reel occurs, causing the transmission cord to be released from one reel and wound onto the other by turn, during which the loops of at least one of the reels gradually varying in radius, thereby adjusting an elastic force provided by the power assembly to the roller. Thus, the user can effortlessly operate the window shade.
