Metallic gas detected in the β Pictoris circumstellar debris disk raises many questions. The origin of this gas is unclear and its very presence is difficult to explain: many constituents of the gas are expected to be radiatively accelerated outward, yet their motion appears to be consistent with Keplerian rotation out to at least 300 AU. Hydrogen has previously been hypothesized to exist in th...

School of Mechanical and Electronical Engineering, East China Jiaotong University, Nanchang 330013, China *. [email protected] Abstract. The multi-objective optimization involves multiple, competing functionality requirements, which is mainly limited to downstream detailed design. Axiomatic design provides the theory to design a complex system top down and deals with multiple functional requirem...

The paper describes the calculation of input parameters for static strength analysis or generative design steering knuckle a Formula Student race car. initial data were: overall and mounting dimensions rim tire, hub brake disk, magnitude force acting on contact patch wheel with road, sliding friction between disk pads, tie rod attachment, location coordinates ball joint mounts caliper. During c...

Brake pad components are important in two-wheeled vehicles because they concern the driver's and others' safety. lining wear is an unavoidable phenomenon. This of concept braking, which involves bringing two things into contact with each other such that press against rub other. pads have not been replaced make brakes unable to work normally, so potential for accidents even greater. One factors ...

Abstract The phenomenon brake squeal has been an ongoing topic for decades, both in the automotive industry and science. Although there is agreement on excitation mechanism of squeal, namely self‐excitation due to frictional forces between disk pad, subject it very complex discover all relevant effects take them into account. Several these problems are related nonlinearities, example, contact p...

Optimization algorithms plays a vital role in mechanical engineering. In this paper we have demonstrated how the Reptile Search Algorithm (RSA) algorithm is able to solve classical engineering design problems. first part, biological reference, as well detailed overview of given. Afterwards, RSA and potential machine class problems The source code for was written using MATLAB R2020a software sui...
