Recoil suppression device, ultrasonic inspection system, impact inspection system, and recoil suppression program

Abstract

To provide a reaction suppression technology for a work machine that cyclically presses or strikes a desired location (where "cyclically" denotes not only a plurality of cycles but also a single cycle), which requires only suppression of a reaction that is small compared to pressing or striking, and achieves size reduction, weight reduction, and energy saving of means of fixing the work machine.SOLUTION: A reaction suppression device 3 causes the center of gravity of a mass section 31 to vibrate in the direction of pressing or striking by a work machine 1. Here, "vibrate" denotes not only a plurality of reciprocal movements, but also a single reciprocal movement. While the work machine 1 is not pressing (pressing) or not striking (striking), the center of gravity of the mass section 31 has a small (large) acceleration in the same direction as (the opposite direction from) the direction of pressing or striking by the work machine 1. While the work machine 1 is not pressing (pressing) or not striking (striking), the reaction suppression device 3 exerts a small (large) force in the opposite direction from (in the same direction as) the direction of pressing or striking by the work machine 1 on fixing means 2 (work machine 1) to counteract the force of acceleration acting on the center of gravity of the mass section 31.SELECTED DRAWING: Figure 2
