Experimenter carries accumulator, the host computer of the output end and operating personnel of spoke type pressure sensor 9 and Hall sensor 22
Signal input part connection.
A kind of application method of portable car-mounted formula taper appliance described in the utility model is as follows：
The first step：To ensure cone index precision, the switching regulator electromagnetism seat 16 in vehicular taper appliance device is adsorbed in
Automobile side car door, the support base 3 by adjusting the telescopic device 1 and telescopic device on the angle of four ends by vehicle body end make
Whole device is bonded completely with automobile side car door, and places level meter in the upper face of bottom plate 7, by adjusting on level meter
Bubble is balanced to ensure that bottom plate 7 is vertical relative to ground；
Second step：Portable taper appliance is in the horizontal position relative to ground, and vehicle operation personnel pass through setting at this time
The 15 drive displacement motor bar 14 of control switch command displacement motor of displacement motor 15 in the car, makes sliding shoe 18 relative to position
The 14 radial extremity movement of motor bar is moved, since sliding shoe 18 and triangular plate 13 are pivotally connected, triangular plate 13 is driven around second
Counterclockwise circular motion is done at angle, and at the same time, 12 first end of gag lever post with 13 third angle of triangular plate due to being pivotally connected, limit
12 first end of bar is done relative to the counterclockwise circular motion that 13 third angle of triangular plate is axle center, and upwards relative to bottom plate 7
Translational motion is carried out, second end and the linear motor holder 5 of gag lever post 12 are pivotally connected, and make linear motor holder 5 with connecting shaft 6 for axis
The heart does clockwise movement, until portable taper appliance is rotated to vertical state, 12 first segment end face of gag lever post and triangle at this time
13 side of plate fits, and closes displacement motor；
Third walks：By the relationship of power and displacement, show that the cone index in car location face, cone index can integrate
Ground reflects soil by machines physical property, he can be used for expressing the rideability of soil, this index is that follow-up off-road vehicle exists
It lays the first stone in the research of road surface passability.
The operation principle specifically measured is as follows, and portable taper appliance is vertical, and experimenter is driven by driving motor 8 at this time
Motor drive rod 11 rotates, and is carried out by the driving nut 19 that 20 level board of taper appliance holder and spoke type pressure sensor 9 clamp
Along 11 radial motion of motor drive rod, the rotation direction of driving motor 8 is adjusted, driving nut 19 is made to be downward uniform motion, this speed
Degree is proportional to the rotating speed of driving motor 8, so that the speed of driving nut 19 straight down is steadily existed by adjusting 8 rotating speed of driving motor
0.5cm/s, driving nut 19 push spoke type pressure sensor 9, taper appliance holder, hollow cylinder 10, nose cone 24 successively.
So the displacement formula of nose cone 24 is as follows：
L=ns
Wherein L is that nut 19 is driven to be inserted into along the displacement i.e. nose cone 24 that 11 axial direction of motor drive rod moves down
Depth in soil.N is the number of turns that motor drive rod 11 rotates, and s is externally threaded helical pitch on motor drive rod 11, due to selection
The external screw thread of motor drive rod 11 is constant, and the external screw thread for the motor drive rod 11 selected in the present embodiment is single thread, institute
Using externally threaded helical pitch s on motor drive rod 11 as known quantity, i.e., externally threaded helical pitch s drives equal to motor on motor drive rod 11
Externally threaded screw pitch p in lever 11；The number of turns n of 8 output shaft of driving motor rotation measures motor driving by Hall sensor 22
The interval times of permanent magnet on bar 11 determine that it is motor drive rod 11 that the interval of Hall sensor 22, which detects permanent magnet once,
It rotates a circle, and when the nose cone 24 that the starting point of number of turns n statistics is hollow cone instrument 10 contacts ground, i.e. spoke type pressure
When force snesor 9 has mutation；Driving nut 19 can be pushed successively under spoke type pressure sensor 9, hollow cone instrument holder 20
The plane at end makes spoke type pressure sensor 9 and taper appliance be identical uniform rectilinear motion, when taper appliance contacts ground,
9 measured value of spoke type pressure sensor has mutation, is at this time the starting point of cone index curve, when taper appliance is inserted into ground depth
Degree reaches 9.5 inches or landing stiffness reach running car by minimum stress 500N when, it is downward to terminate driving motor 8
Driving, measurement process terminates at this time.Driving motor 8 inverts, and drives 13 upward uniform motion of nut, by driving taper appliance holder
20 level board makes taper appliance holder 20, pressure sensor 9 and taper appliance go up, until initial position.It completely completes at this time
The one-shot measurement of ground cone index；
Taper appliance is measured not in contact with the power F before ground by spoke type pressure sensor 91And taper appliance is on ground
Stress F in soil2, it is calculate by the following formula and obtains ground reaction force：
F=F2-F1
Wherein F is ground pressure, is inserted into the variation of depth L in soil with taper appliance and changes；24 parameter of nose cone has been given
Fixed, nose cone 24 is pressed into ground with the speed of 0.5cm/s, and the formula for calculating cone index is：
Wherein CI values are cone index, and A is the conical projection area of nose cone 24, and F is ground pressure required by above formula.
4th step：Rectangular coordinate system is established, using each obtained CI values that measure as the coordinate system longitudinal axis, the circle of the secondary measurement
The insertion depth L of conehead 24 obtains the figure of insertion depth L variations of the cone index CI with nose cone 24 as coordinate system horizontal axis
