Utilize principle that the bionical detection machine people of physical properties of food carries out the bionical detection operation of physical properties of food as shown in Figure 7:
At first, according to the different characteristic of various food and the rerum natura of required detection, mode of motion with bionical detection machine people, interlock, mill are pressed or are sheared, calculate the corner numerical value of the servomotor of the secondary mechanism of six ball pair-moving sets of driving of various modes-ball (SPS), be stored in the database of host computer.
In bionical oral cavity, put into the food of required detection during each the detection, in bionical oral cavity, inject simulate saliva by the saliva inlet; Bionical detection machine people humiture test box be can be put into, needed temperature and humidity controlled; According to actual requirement, from the host computer database, obtain corresponding controlled variable, these numerical value are converted into pulsed quantity send to servomotor by single-chip microcomputer.
The rotation of servomotor realizes the shortening or the elongation of expansion link, thereby makes chin carry out bionical chewing according to the programmed value of setting.When bionical detection machine people carries out masticatory movement, be installed in intraoral various sensor data such as intraoral power, displacement, humidity, temperature are converted to electric signal, be converted to digital signal and send single-chip microcomputer to by modulus conversion chip; Host computer is connected with Single Chip Microcomputer (SCM) system by serial ports, and the data of sensor acquisition are transferred to host computer by the RS232 serial ports.
The trace routine of host computer notes that tested food is stretched, compresses, the stress data when shearing in the masticatory movement process, the physical data of tested food in masticatory movement, for example shape, size etc., the stress data of tooth in the tested food masticatory movement process, the decomposition data of tested food.Utilize these record data, the rerum natura transitivity of calculating food changes, and the mouthfeel of comprehensive assessment food, food is to the oral cavity health affected, the nutrition digestion degree of absorption of food.
Food is drawn stress time curve in the data of the distortion of being chewed the food in the process, stressed and time under the sensor record, is horizontal ordinate with time, and stress is ordinate, and the pressure transducer detected value is for just, and the pulling force sensor detected value is for bearing; Distortion-time curve is a horizontal ordinate with time, is deformed into ordinate; Stress-deformation curve to be deformed into horizontal ordinate, is an ordinate with stress; According to these curves, relevant rerum natura Data Detection method is as follows.
1. bite (hardness): the pairing power of peak-peak on the stress time curve, numerical value is big more, illustrates that food is hard more, has bite more.
2. stickability: the following negative peak area of horizontal ordinate line on the stress time curve, the stickability of expression food, this absolute value is big more, and the expression food viscosity is strong more, and the food mouthfeel sticks to one's teeth.
3. elasticity (pull-off force): represent that with the product of pairing power of peak-peak and stretching distance numerical value is big more on stress-deformation curve, stretching distance is long more, and then food elasticity is good more.
4. extensibility (stretching time): break the food required time from beginning to be stretched on the distortion-time curve, this value is big more, and extensibility is good more.
5. toughness: food is chewed when cutting off on stress-deformation curve, the product of cut-out power and breaking distance, the merit of being done when promptly cutting off; This numerical value is big more, and toughness is just good more.
6. maximum cut-out power: the pairing power of peak-peak on stress-deformation curve, numerical value is big more, and power used when cutting off food is big more.
More than describing is to explanation of the present utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the utility model spirit, the utility model can be done any type of modification.
