Abstract: In the real venicle testing, evaluating the mechanical properties of the clutch just depend on the related characteristic point on mechanics characteristic curve at present, The evaluation method failed to make full use of the informantion included in the characteristic curve and may lead to miscalculation. According to the stuation, by parameter transform can get clutch undamped mechanical characteristic. Through the method of regression analysis, then the qualify can be judged by comparing the test curves of clutch undamped mechanical characteristics with the curve of modeling. Experimental results show that the new evaluation method is feasible.

Abstract: In order to reduce the cost of washing machine clutch, clutch manufacturing process to improve through conventional washing machine JLX-N-5.0 clutch structure analysis, a new structure of the washing machine clutch, in ensuring the technical performance of the major premise, the clutch brake structure was improved to cancel one-way bearing, narrow diameter brake wheel, change the brake means and planetary gear train positioned. Comparative experimental results show that the clutch brake performance and a substantial increase in operating performance, with simple technology and low cost characteristics.

Abstract: In this paper, we designed a prototype of powered above-knee prosthesis. Compared with other prototypes available in the literature, our designed prosthetic leg employs a redundant actuator concept to overcome the challenge faced by the single-motor transmission systems. The redundant actuator also enables the prosthesis to be partially functional when the prosthesis loses power. Finally, in order to provide optimal control parameters for designed above-knee prosthesis to perform a smooth level-ground walking task, an inverse dynamic model based on Kane’s method is constructed.

Abstract: Based on the embedded flexible clutch mechanism as the breakthrough point, using ADAMS dynamic analysis software and ANSYS simulation analysis software, established the analysis model, the peak impact force between the different conditions of brake wheel and brake claw was obtained, the brake wheel and the brake pawl two allowable angular speed difference. At the same time to brake wheel and brake claw structure impact resistance ability as optimization objective, the different structural forms of brake wheel and brake claw structure peak impact in different conditions and the brake wheel and brake claw two permissible angular speed difference is analyzed and calculated.

Abstract: The analysis of the sliding contact behavior for friction lining is an important issue in design of centrifugal clutches. In this study, a numerical model based on the moment equilibrium and contact mechanics has been developed to analyze the dynamics of a commercial centrifugal clutch. The proposed dynamic model can estimate the rotational speed of initial contact, output torque, and contact pressure for friction lining during the clutch operation. The comparison of the numerical and experimental results for the output torque of the analyzed centrifugal clutch shows the simulation agrees well with the experimental data. The difference for the maximum output torque is around 1.9%, which shows the effectiveness of the proposed method. The proposed dynamic model can reduce unnecessary physical prototypes and experimental cost, and is expected to be used to improve the design of the centrifugal clutches.

Abstract: Thermoelastic instability of multi-disc clutch contributes to the failure of power transmission and as such multi-disc clutch is considered as a research object with a theory model built on perturbation method. The characteristic equations on the thermoelastic instability of geometrically symmetrical and antisymmetrical steel-disc are derived. The results are shown that both wave number and disc thickness have significant influences on the thermoelastic instability of the steel-disc. Choosing a larger wave number or a thicker steel-disc can prevent the thermoelastatic instability state in multi-disc clutch. Compared with the geometrically symmetrical steel-disc,the geometrically antisymmetrical steel-disc is more susceptible to thermoelastic instability.

Abstract: Energy is vital to machines and equipment basic functioning. On the other hand, it has an ambiguity determined by its detrimental side under other circumstances. This paper aims to present a review of simple laws of physics / mechanics in order to understand some benefits of using such energies (kinetic and potential energies), in order to process products or generating movement (mechanical energy). However, also shows its damaging side for driving systems, where such energies may generate catastrophes, usually due to high impacts. This last, which destroys complete or partial systems due to the absence of any robust / preventive protection. There is a safety manner (solution) to protect the systems, described along the text.

Abstract: Establish the simplified model of 215 clutch. Then made grid division and apply the boundary conditions to the model to do CFD analysis in ANSYS CFX module. According to the results, a new pressure plates structure is suggested. The gap between the supporting platforms against the diaphragm spring is designed into bevel and the number of the supporting platform is increased from 6 to 9. The result of the new structure shows that the air flows quickly than the original one. In other words, the convection between the air and the pressure plate is improved, and it contributes to reduce the temperature rise.

Abstract: Based on intensive study to variant design method in product parametric technology,the paper put forward to rapid design system which have been successes used in clutch company, The tabular layouts of article characteristics describe standardization and regularization information of product , can expediently implement the product variant design and variant response of downstream process. The method firstly computes clutch parameters according to outside requirement, then inquired if there is existed product, then decided whether to design a new product or get original product. After this process, then acquire the product main model, which can abstain geometric model and realize some other analysis and virtual simulation, at last, generated satisfying product. The method in this paper have been successful used in clutch company’s design process, and highly improve it’s products creation ability and products competition in market.
