Embodiment
[0078] Some details in the technical solutions of the present invention will be further described below with reference to the accompanying drawings.
[0079] A specific embodiment of the present invention takes a satellite waveguide switch as an example, and designs a reinforcing sheet according to the configuration characteristics of the waveguide switch itself. The area where the stiffness of the waveguide switch needs to be enhanced is the RF housing area near the root of the flange. Under the action of external stress, the RF housing in this area is easily deformed, causing the inner rotor to be stuck. The reinforcement sheet needs to form a closed stress transfer ring between the switch flange and the RF housing, so it can be designed as a trapezoidal reinforcement sheet with a certain thickness H, and is bonded between the flange and the RF housing by structural adhesive. The reinforcing sheet can form a closed stress transfer ring.

Abstract
The invention relates to a flexural rigidity enhancing structure of a satellite waveguide switch, which belongs to the waveguide switch and comprises a driving shell, a driving motor, a radio frequency shell, a radio frequency rotating shaft and a switch flange, a rotor of the driving motor is fixedly connected with the radio frequency rotating shaft, the driving motor is mounted in the driving shell, and the radio frequency rotating shaft is mounted in the radio frequency shell. A switch flange is arranged outside the radio frequency shell and is used for connecting the waveguide; a gap exists between the radio frequency shell and the switch flange, the radio frequency shell is characterized by comprising N reinforcing pieces, N is larger than 1, the reinforcing pieces are bonded between the radio frequency shell and the switch flange through an adhesive layer, and the N reinforcing pieces, the radio frequency shell and the switch flange jointly form a closed stress ring. The stress transfer is in a closed loop, and meanwhile, the original assembly precision requirement of a product is ensured, so that the organic unification of small additional deformation and high rigidity enhancement is realized.
Description
technical field [0001] The invention provides a flexible, reliable and effective rigidity enhancement structure for precision instruments, realizes the organic unity of small additional deformation and high rigidity enhancement, can perform post-remediation for products with insufficient structural rigidity, and has significant economic benefits. The invention belongs to the technical field of mechanical engineering. Background technique [0002] The waveguide switch is a key component of the satellite payload and is mainly used for the loop backup of the amplifier in the satellite transponder subsystem to improve the reliability of the satellite. The working principle of a typical waveguide switch is as follows: after the drive motor receives the command signal, it provides rotational torque, which drives the motor rotor and the RF shaft to rotate toward the target state. After reaching the position, the locking magnet provides the locking torque to keep the switch in worki...
