Tactile sensors are devices or systems that can provide measurements for objects’ properties or contact events through the process of actual contact between the object and sensor.
Nevertheless, there are significant factors to be accounted for during the sensor fabrication viz. sensitivity, flexibility and stretchability. 2.
Research Aims The objective of this study was to design a conductive fabric tactile sensor with stretchable properties for measuring muscle activity by using commonly available conductive stretchable materials.
These properties were deemed suitable for applications which required low resistance.
The fabric’s beneficial properties in varied e-tactile applications have been proven before.

However, after conventional fusion joining, e.g. after laser beam welding, heat affected zones, porosity or grain growth may occur and impair the local properties [1, 2].
Beside mechanical properties of compound the formation of bonding zone are presented.
Due to the different material properties the production process of compounds has to meet sophisticated requirements.
The emphasis of the investigations is thereby on the formation of the bonding zone and the determination of the compound properties of the compounds.
The influences of the initial joint before the co-extrusion process and the material combination on the bonding properties are of interest.

The main purpose of the critical speed analysis is to determine the critical speed of the rotor, adjust the critical speed according to the experience or relevant technical regulations, and make it properly away from mechanical work speed, so as to get reliable design The Design of Ultra-high Speed Rotary System Three dimensional model diagram of the high speed friction and wear test system is shown in Fig.1.
When high speed wheel rotates, because of the factor of the rotary table mass imbalance, the centrifugal force generated will lead to occur corresponding bending of rotary system axis.
The calculation method of rotor critical speed directly affects the calculation accuracy of each order critical speed, so we should try to choose appropriate calculation method to make the mathematical model and boundary conditions accord with the actual situation as far as possible [6].
Fig.5 Shaft section mechanical analysis Conclusion In the critical speed calculation process using the transfer matrix method in the past, with the addition in spreadsheet frequency ω, it will make the calculated precision below, the reason is that certain factors in the transfer matrix have relation with ω2, it will occur the subtraction between the two close to the value in the calculation of the high-end frequencies and mode shapes, greatly reduces the computational accuracy.
A New Method for Evaluation of Mechanical Properties of Sealing Coating[J].

The treatment of oily wastewater poses significant environmental and economic challenges, necessitating innovative solutions that combine effective separation technologies with enhanced antifouling properties.
Despite the permeability improvement, it is believed that the filtration system should be optimized by incorporating membranes with high antifouling properties, thus has become the objective of this study.
To improve the membrane antifouling properties, a 7wt% of tannic acid (TA, Sigma Aldrich) and 1 wt% of PVP (average Mw ~10,000) were added to the polymer solution containing 15wt% of PVDF.
Result and Discussion Membrane properties.
This improvement can be attributed to two factors: increased surface hydrophilicity and the presence of large surface pores.

Different organized text resouces are related with each other according to similarity of specific topics.As a result, degree of polymerization of content and information of text is improved.However, knowledges of type selection of clutch are still discrete and exist in unstructured and independent text.These knowledges need further to be extracted as knowledge element and processed to form into structrual knowledges.The essence of knowledge structuring is associating and locating of knowledge.Fragmented knowledge can be converted into orderly and structrual knowledge with the back of contextual background knowledge through knowledge structuring.It makes knowledge nodes have ID number, reasonable properties and associations with each other.
The algorithms and steps of extraction of knowledge element are listed below: Name and index information of feature of knowledge element are defined through hierarchical analysis to finishing text; Retrieve the key elements in the text as a triggered mark.Different semantic blocks where the key factors are located in text are processed by pattern matching to determine the legality of factors of knowledge elements.The key elements mainly come from concepts and properties of ontologies which have the similar name as knowledge element; Relations between semantic block and name of knowledge element are established according to critical elements' classification in the factors of knowledge elements; Semantic net based on knowledge elements is constructed according to the struct of knowledge element to realize structurual presentation of knowledge element; Construct relations of factors of type selection according to structurual representation of knowledge element; As is shown in the figure
These criterias are clarity,coherence,extendibility,minimal encoding bias and minimal ontological commitment.Different agents are linked to outer layer of entire knowledge net in the figure 3.Methods, properties and algorithms,etc, related to leaf nodes are encapsulated in the body of Agent.
Knowledge resources can be obtained through triggering intelligent agent program which is satisfied with trigger conditions.Specific domain knowledges are organized in the corresponding intelligent agent with the form of agent directory.It has two advantages to organize knowledge resources of leaf nodes through independent intelligent agent.Firstly,knowledge of relevant attribute class and the factual class can be extracted easily,such as checking formulas and parameters,etc,so it is easy to establish knowledge network with better abstract structure.Secondly, It assure consistency of knowledge and data through encapsulating all kinds of specific factual knowledge resources in different intelligent agent.So knowledge has the properties of mutual independence and it is convenience to access and knowledges can be operated by corresponding intelligent agent.

On the basis of analyzing the �-potential of nanodiamond particles, the influence of chemical mechanical treatment (CMT) on the dispersion stability and infrared spectra of nanodiamond was studied.
But the existence of aggregates affects its characteristics as a kind of nano-scale particle.
When used for ultrafine polishing, (hard) aggregates cause nicks on the surface of workpiece which affect the roughness of finished workpiece.
The formation and properties of nanodiamond aggregates are very complicated.
This work aims at the factors affecting the �-potential of nanodiamond in order to get its disaggregation method.

However the existing test equipments generally can only simulate a single environment of high static fields or shaking load for testing and validating mechanical properties of structures and materials.
Some unknown factors make shakers with stable and high performances produce waveform distortion and instability, even difficult to work [4].
In return, these deformation and movement affect the control performance of shakers.
So hinged shaft is the core component affecting the control performance of shaker and safety of arm, and its stiffness and damping must be designed with calculation and analysis in practical construction of equipments.
High exciting force of shaker makes bucket deform and move, affect the control performance of centrifugal shaker.

Plastic deformation during rotary rolling leads to a change in the size of the blank for ball pins, their strength properties, surface roughness and material structure [2,3].
All this negatively affects the performance of the car’s suspension.
Based on the many experiments carried out, it can be concluded that the main factor in ensuring operability of ball joints is roughness of the head surface, which is in contact with a polymer insert.
In addition, it was found that when protection of the joint is violated, its performance is still affected by wear resistance of the polymer insert and the spherical surface of the ball pin, which depends on its hardness.
