Embodiment Construction
[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0020] Aiming at the problems of numerous and wasteful structure simulation parts in the past, the present invention proposes a design scheme of a mass stiffness adjustable device, and studies the realization of mass adjustment and stiffness adjustment. After the design scheme is determined, the simulation analysis is carried out, and the structural parts are processed for test verification.
[0021] Such as figure 1 Shown is a schematic diagram of the simulation device. It can be seen from the figure that a simulation device with adjustable mass stiffness for impact testing includes a mounting base 1, an adjustable rib plate 2, a supporting vertical plate 3 and a counterweight device 4; the mounting base 1 is placed horizontally ; The installation base 1 is a square plate structure with a side length of 295-305mm; the upper surface of the inst...

Abstract
A mass and rigidity adjustable simulation device used for an impact test relates to the structure simulation device test field. The device comprises an installation pedestal, an adjustable rib plate, a support vertical plate and a counterweight apparatus. The installation pedestal is placed horizontally. The support vertical plate is parallel to a side edge of the installation pedestal and is fixedly installed on an upper surface of the installation pedestal. The support vertical plate is vertical to an installation pedestal surface. The adjustable rib plate is fixedly installed on the upper surface of the installation pedestal. A side edge of the adjustable rib plate is vertically contacted with a side surface of the support vertical plate. The counterweight apparatus is fixedly installed on a side surface of the support vertical plate, wherein the side surface is far away from the adjustable rib plate. Aiming at previous problems that there are many structure simulation components and a waste situation is generated, a design scheme of a mass and rigidity adjustable device is researched and realization modes of mass adjusting and rigidity adjusting are researched. The device is suitable for different models of products. Cost can be greatly reduced and time cost is decreased.
Description
technical field [0001] The invention relates to the test field of a structural simulation device, in particular to a simulation device with adjustable mass stiffness for an impact test. Background technique [0002] Impact test is required for model task product identification and some positive samples. The impact test is characterized by a short time course (millisecond level) and a large magnitude (above 1000g), and the test equipment cannot be closed-loop controlled. Therefore, it is necessary to consider the use of analog parts for test impact and debug the state of the equipment system to meet the required test requirements. At the same time, it is clearly stipulated in the test standard GJB 150.18A-2009 Military Equipment Laboratory Environmental Test Method Part 18: Shock Test, GJB 1027A-2005 Vehicle, Upper Level and Spacecraft Test Requirements and General Environmental Test Specification Documents that the impact test must be Use structural parts to conduct pre-tes...
