Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with embodiment, further set forth the present invention.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; Dismountable staged three-dimensional strength measurement device of the present invention; Mainly form by three-dimensional strength measurement platform 100, stepped support formation 200, guide rail structure 300 three parts; Described three-dimensional strength measurement platform 100 comprises four pressure transducers 110, circuit board 120, objective table, data acquisition system (DAS), an amplifier and a processor, and ergograph is placed on the lattice supporting framework; Described stepped support formation 200 is made up of the many rectangular body rods 210 of aluminium alloy, and on every bar track is arranged all, is convenient to load onto guide rail structure; Described guide rail structure 300 comprises four slide blocks 320, is installed on the track 310 on the bar, and ergograph can be slided front and back; Described staircase boards mainly is made up of a rubber slab, and it is tabular also can be that other material is made, and is placed on the lattice supporting framework through screw.
Described three-dimensional strength measurement platform 100 mainly is made up of four piezoelectric transducers, circuit board 120, an objective table, a data acquisition system, an amplifier and a processor.Ergograph is fixed on the supporting construction through described guide rail structure 300, both can slide in the above, also can disassemble independent dynamometry.Ergograph is divided into two parts up and down, puts four sensors above, circuit board 120 of underneath.In top; Sensor connects above that through screws, bolts, and four piezoelectric transducers are to arrange in the position that the human body sole is put according to stair activity the time, and the right and left has two sensors respectively; Arrange before and after right latter two sensor, just in time the power that receives of two foot bottoms of energy measurement; In the lower part, have only a circuit board to be placed on wherein, through the right cylinder 130 on four angles, the position of fixing circuit board.There is an output terminal lower part of ergograph, comes CC plate and data acquisition system (DAS) through special lead.Mainly be to be used for surveying the human body power that sole receives of going upstairs during experiment, can also measure the power of other types.The power that sole receives is converted into electric signal through pressure transducer, and electric signal is transferred to data acquisition system (DAS) along circuit board, and then resonance-amplifier amplifies electric signal, at last through processor, the electric signal after amplifying is converted into force value, is presented on the screen.
Described stepped support formation mainly is made up of a truss-frame structure and a staircase boards (quantity of staircase boards also can be regulated as required) that comprises many bars (quantity of bar can be regulated as required).Truss-frame structure be shaped as notch cuttype, material is an aluminium alloy, connecting in layer can be put ergograph on it then.The position of especially putting ergograph will increase by two bars to be supported, the power of disperseing ergograph to bear, in case since stressed excessive, damage supporting construction by pressure.Staircase boards is connected on the truss-frame structure through screw, and the staircase boards size is identical with the apartment stair size of standard, but material is the Wood-plastic composite material.
Described guide rail structure mainly is made up of four slide blocks and track.Track is directly on bar, to cut out, and sees the trapezoidal of a band fillet over from end face.Four slide blocks are placed on respectively on the track of two bars, and there are threaded hole 330 in slide block central authorities, are convenient to the fixing of ergograph and slide.
The implementation step of the stressed situation in vola is when measuring stair activity:
Be installed in ergograph on the guide rail mechanism, connect circuit after, whether the inspection circuit has looseningly, prevents loose contact.
Must the proving installation data be returned to zero before the test, otherwise can very big influence be arranged the test result of back.
Also to the vola be stepped down in before the test and see if there is signal output on the ergograph, if it is data show on the computer screen, then normal; If no datat shows, then strengthen the data of observing output again behind the pressure in vola, if still there is not data presentation, then is likely and do not export signal or the output signal is too little, need the connectivity problem and the resonance-amplifier of inspection circuit.
Because the variable of this experiment is a lot; Such as; Speed when going upstairs, have or not wear shoes, posture, position on staircase boards, vola or the like when going upstairs of pin when going upstairs; And everyone sex, age, height, body weight be not the same, so we need constantly carry out reference and contrast, and prerequisite is to keep under the remaining variables situation always.When doing experiment, we have recruited the volunteer from the campus, and for there being following situation person to get rid of: lower limb had injured history in nearly six months, had lower extremity surgery, back and the pelvis of any kind of disease, nerve muscle disease to be arranged and equilibrium problem etc. is arranged.The volunteer who has finally chosen 40 health has participated in this time and has measured, and the essential information of sample sees the following form:
Each sample is measured, guaranteed earlier during measurement that its dependent variable is certain, the people steps down on the ergograph then, upwards walking, and the data on the computer screen can constantly change at this moment, and these instantaneous data also can all be recorded in the computer.
According to the data of being surveyed, but the stressing conditions in analyst vola when stair activity.
This device can also cooperate with motion capture system except above-mentioned application, and the lower limb of human body are carried out dynamic analysis.According to the data that motion capture system and vola power measuring table are gathered, calculate the hip, knee and the ankle-joint that are obtained in a period of motion along X, Y, (black solid line is represented sample average to the suffered joint power change curve of three directions of Z; Fascia cinerea is represented sample variance.Wherein each research object is all got following 1 complete period of motion of each situation, finds the solution average and variance processing acquisition then through normalization).
The go upstairs joint of lower extremity power in when motion of all research objects is added up, obtain the upper limit, lower limit and the whole variation range of table 2 listed lower limb hip, knee and the ankle-joint joint power on three directions when different action.Represented numerical value is the ratio (units) of joint power (N of unit) and its body weight, so their unit is N/kg.Wherein, along the suffered joint power of positive dirction, negative value is represented along the suffered joint power of negative direction on the occasion of expression.Below be that we do the data form that obtains when testing.
The go upstairs joint of lower extremity moment in when motion of all testers is added up, obtain the upper limit, lower limit and the whole variation range of table 3 listed lower limb hip, knee and the ankle-joint joint moment on three directions when different action.Represented numerical value is the ratio (units) of joint moment (Nm of unit) and its body weight, so their unit is Nm/kg.Wherein, along the suffered joint moment of positive dirction, negative value is represented along the suffered joint moment of negative direction on the occasion of expression.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the instructions just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
