Four-channel steering engine controller resistant to overload and large temperature impact

Abstract

The invention discloses a four-channel steering engine controller resistant to overload and large temperature impact. The controller includes a controller shel, and an assembled circuit assembly is arranged in the controller shell; an insulating damping layer is arranged at the bottom of the assembled circuit assembly, a throwing cable electrically connected with the outside is arranged on the assembled circuit assembly, the assembled circuit assembly is fixed in the controller shell through a standard part and is encapsulated through pouring sealant, and the controller shell forms a solid body through the assembled circuit assembly and the pouring sealant. According to the four-channel integrated steering engine controller, a digital control circuit and a power driving circuit are integrated, in a limited structural space, the four-channel integrated steering engine controller is electrically connected with the outside in a line throwing mode through circuit integration and potting reinforcement, the ultrahigh overload capacity is achieved, the overload magnitude reaches 23000g, and meanwhile the use requirement of the high-temperature-impact-resistant environment is met. The problem that an electric servo mechanism is small in structural space and high in environment resistance is solved, and the ultrahigh overload steering engine controller is achieved.

Description

Technical field [0001] The invention relates to a four-channel steering gear controller, in particular to a four-channel steering gear controller that is resistant to overload and high temperature shock. Background technique [0002] With the emergence of new materials and new technologies, the rapid development of anti-high-overload guided projectiles has resulted in extremely high overload loads when guided projectiles are launched. This loading environment has brought a lot to the design and assembly of mechanical components of the steering gear. It may cause structural damage and damage to the electronic components of the steering gear controller, making the system unable to operate normally. For this reason, the steering gear controller needs to potting and strengthening the electronic components, and at the same time adopt a cushion to absorb the overload impact energy to achieve the purpose of improving the force environment of the controller. [0003] The conventional stee...
