Acceleration Analysis

Shock test of marine diesel engine is the important content for ship anti-shock research. Plentiful shock tests of equipments have been carried out abroad, but there is no detailed test methods of diesel engine. According to simulation results, 8-channel acceleration test points are determined. Because diesel engine is working, the measured shock acceleration is interfered by vibration signal. Orthogonal wavelet decomposition and wavelet noise reduction methods are used to separate shock component from test results. The seperated shock component consists of two parts. One is the low-frequency part caused by the shock from diesel foundation and then attenuation through the isolator, the other is the high-frequency part caused by the secondary shock of the retainer.

This paper presents the steps involved in the design, analysis and fabrication of a six-legged walking machine. The suggested machine uses the basic four bar chain mechanism and slotted lever type quick return mechanism with some modifications. The synthesis of the link lengths is based on Freudenstein’s (algebraic) three accuracy points. The velocity and acceleration analysis of oscillating links explains the effect of change in the crank’s angular velocity and acceleration on all other links. The suggested machine is capable of moving forward and backward, turning right and left and rotating around a point on the commands given.

Special Case

Abstract The screw algebra is used to efficiently derive expressions in compact form for both the angular accelerations of the moving links and the linear accelerations of points on the links of platform-type manipulators. The analysis employs the property that the acceleration state of the manipulator platform can be determined by considering the acceleration states of the links of only one — any one — of the manipulator legs. The obtained expressions provide an ease in symbolic and algebraic manipulation. The analysis is then extended to specify the acceleration center point of ithe nstantaneous motion of the manipulator platform. The acceleration center point is then used in expressing the distribution of the acceleration field of the platform instant motion which is important in manipulator synthesis. The special case of planar manipulators is studied and simpler expressions are derived. Numerical examples are presented for the analysis of a 3-DOF planar platform-type and of a 6-DOF spatial “Stewart Platform” manipulators to illustrate the analysis procedure.

The Impact

Telah dilakukan analisis percepatan tanah maksimum gempa bumi di Kota Manado menggunakan metode Donovan dan McGuire. Kota Manado merupakan bagian dari lengan utara Pulau Sulawesi terletak pada batas pertemuan beberapa lempeng besar sehingga wilayah ini sangat rawan akan goncangan gempa bumi. Upaya mitigasi perlu dilakuakn sejak dini untuk memperkecil dampak resiko gempa bumi tersebut. Salah satu upaya mitigasi adalah memetakan percepatan tanah maksimum (peak ground acceleration) di permukaan. Penentuan variasi nilai percepatan tanah maksimum menggunakan metode Donovan dan metode McGuire. Data yang digunakan adalah data hypocenter gempa yang dikumpulkan dari dua katalog yakni data USGS dan ANSS selama selang pengamatan Februari 1963 sampai Agustus 2017 meliputi radius 500 km dari Kota Manado. Hasil analisis menunjukkan bahwa percepatan tanah maksimum di Kota Manado menggunkan metode Donovan sekitar 42.12 gal sampai dengan 51.82 gal sedangkan metode Mc Guire diperoleh nilai percepatan tanah sekitar 59.13 gal sampai 72.53 gal.The peak ground acceleration analysis in Manado city has been done using Donovan and McGuire method. Manado City is part of the north arm of Sulawesi Island located at the boundary of several major plate meetings so that this region is very prone to earthquake shocks. Mitigation efforts need to be done early to minimize the impact of the earthquake risk. One mitigation effort is to map the peak ground acceleration on the surface. Determination of peak ground acceleration variation using the Donovan and McGuire method. The data used are earthquake hypocenter data collected from two catalogs namely USGS and ANSS data during the observation interval February 1963 to August 2017 covering a radius of 500 km from Manado City. The result of the analysis shows that the peak ground acceleration in Manado City uses Donovan method about 42.12 gal up to 51.82 gal while Mc Guire method obtained the peak ground acceleration a value of  about 59.13 gal to 72.53 gal.
