Method for preventing breakpoint of rotary multi-gear switch

Abstract

The invention relates to a method for preventing a breakpoint of a rotary multi-gear switch. The method comprises the following steps: step 1, determining a coaxial series installation mode of a kinetic potential energy conversion mechanism and a gear switching mechanism; 2, the pre-rotation angle theta < storage > of the kinetic potential energy conversion mechanism is determined, a compression spring with the rigidity coefficient of k1 is selected, the initial installation torque M0 of the compression spring is determined, and the installation radius r < spring > of the compression spring is determined; 3, determining that the design of the kinetic potential energy conversion mechanism meets the monotonic increase of the torque, the maximum torque M < storage > and the elastic potential energy EP; and 4, on the gear switching mechanism, the positioning number n, the wedge angle theta wedge, the rotating angle alpha corresponding to the wedge edge and the rotating angle gamma of the smooth section are determined, and n compressed springs with the rigidity coefficient being k2 are selected. The invention has the remarkable effects that: when the switch gears are switched, the torque of the whole mechanism is not zero all the time, the instantaneous jump of adjacent gears can be passively realized without depending on an operator, the stop between the gears is avoided, and the breakpoint is avoided.

Description

Technical field [0001] The present invention relates to the field of rotary multi-gear switches, in particular to a method of preventing breakpoints in rotary multi-gear switches. Background [0002] In order to improve the agile response and flight reliability of military aircraft combat output, pilots require all types of aircraft to have the ability to achieve a reliable, safe, comfortable, efficient and personalized concept of cockpit. With more and more aircraft functions, the control man-machine interface in the cockpit is becoming more and more complex, the pilot's mental workload will be larger and larger, and its human indicators such as operation response time, speed, and force feedback sensitivity will show different degrees of reduction, especially when multiple functions are operated at the same time, the degree of reduction will be increased several times, greatly increasing the control time. Foreign rotation band operation (4 to 12 positions, non-polar motion) clas...

Problems solved by technology

With more and more aircraft functions and more and more complex man-machine interface in the cockpit, the pilot's mental workload will increase, and the human body indicators such as operation response time, speed, and force feedback sensitivity will all be affected. Shows different degrees of reduction, especially when multiple functions are operated at the same time, the degree of reduction will be increased several times, greatly increasing the operating time

Foreign countries do not have the technology to avoid breakpoints and achieve rapid jumps for core devices operating in the rotary band (4 to 12 positions, infinite movement). Generally, methods such as improving the machining accuracy of parts and optimizing the sense of operating force are used to compensate for the slow operating speed. Insufficient, but when the operation is very slow, there may still be equipment failures caused by breakpoints and asynchrony. For important on-board equipment failures, such as engine shutdown, weapons cannot be dropped in an emergency, etc., causing serious safety accidents
