Description
Technical field
The utility model relates to a kind of falling device for fall-down test, particularly relates to a kind of ultra-large type falling device utilizing potential energy and kinetic transformation to cushion to fall potential energy and impact.
Background technology
Fall-down test equipment be a kind of utilize earth gravity field to simulate transport, use in product fallen and the important scientific experimentation device of the mechanical collision such as impact.By the importance index that the anti-drop ability of this device inspection product is reliability design, for rational Package Design provides important research means.
Fall-down test device is generally made up of a few parts such as hoisting gear, releasing mechanism, attitude maintaining body, buffer gear and leak control and check equipment.Wherein, attitude maintaining body is control the important feature that product target attitude.The fall-down test course of work is: fall-down test device by experiment product by lift mechanism lifts to certain altitude, control system assigns the instruction once discharged, and attitude maintaining body falls together with experiment product.When dropping to certain altitude, experiment product is separated with attitude maintaining body, and (secondary discharges)---experiment product target, and attitude maintaining body is by buffer gear buffering, the remaining kinetic energy of absorption attitude maintaining body.Therefore, attitude maintaining body and buffer gear are one of emphasis of large-scale fall-down test device design.
Snubber assembly generally can be divided into accumulating type and energy-dissipating type, mainly contains spring-rubber impact damper, draft gear, elastic cement buffer, hydro-pneumatic buffer, bydraulic buffers, combined buffer and utilizes the foamed aluminium impact damper etc. of deformation energy.
Along with the development of related science research is with deep, for meeting ever-increasing falling height requirement, the scale of fall-down test device constantly increases.The thing followed is that the physical dimension of attitude maintaining body and weight increase, and this brings challenge to the structural design of attitude maintaining body and snubber assembly and manufacture thereof.
Usually, attitude maintaining body is by a pair guide rail for sliding, straight down and a guide frame orbited, each guide rail end is provided with buffering energy-absorbing mechanism, in order to opposing and take away from tens of meters of placement in heights, the huge kinetic energy that produces of the guide frame of several tons of weights.On the other hand, the landing area that must be positioned over experimental piece due to buffering energy-absorbing mechanism is overseas, and this makes the distance between two buffering energy-absorbing mechanisms comparatively large, when also just meaning guide frame and two buffering energy-absorbing mechanism contacts, because center of effort span is comparatively large, guide frame subjects larger moment of flexure.Huge kinetic energy and larger moment of flexure make buffering energy-absorbing and guide frame device very easily destroy.For avoiding this phenomenon to produce, not only need when designing to adopt comparatively reasonably buffering energy-absorbing structure, but also need reduce the quality of guide frame and adopt the material having better mechanical property, work in-process requires strict to its mass property.
In order to resist the destruction of larger kinetic energy to guide frame, guide frame is higher to Structural strength calls, makes its quality comparatively large, thus produces larger kinetic energy; The design of snubber assembly then requires the structural safety ensureing self on the basis absorbing this kinetic energy.When kinetic energy is brought up to a certain degree, the structural design of guide frame and snubber assembly and material performance requirement are reached capacity level.Trace it to its cause, mainly adopt Mechanical Contact mode to carry out kinetic energy buffering, force the kinetic energy of offsetting guide frame.Along with falling height increases, the physical dimension of guide frame and quality increase, and huge kinetic energy brings snubber assembly and guide frame very easily produces destruction, and design and difficulty of processing increase, manufacture and use cost are increased.
