The vibration signal of diesel engine is typically non-stationary and time-varying signal, with complicated transient components. With adaptive concentration method controlled by an additional parameter m, an adaptive generalized S transform (AGST) is developed in this paper. The simulation shows that the AGST method has a better time-frequency resolution than S transform. The AGST method is then applied to analyze the vibration signal of the cylinder head cover of a four-cylinder diesel engine. The result indicates that the time-frequency representation of the vibration signal obtained by AGST has a good resolution, and the vibration components, such as combustion shock and valve-slap, can be exactly identified. The research is of great significance for the structural optimization and vibration control for the diesel engine.

Cure Shrinkage

In this paper, one kind of low profile SMC (Sheet Moulding Compound) has been introduced and used to produce the cylinder head cover. Two kinds of low profile additives (polystyrene and polyester resin) were blended and added to the resin to compensate for the cure shrinkage. The cure shrinkage of obtained low profile SMC was only 0.05%, which met the requirements for class A surfaces. Test sample were prepared by mould pressing. Properties testing of SMC were conducted according to the National standards. Results showed that all of the indexes of the low profile SMC met the specifications for the production of cylinder head cover. Some properties of cylinder head cover products have been investigated in detail. Experimental and performance testing results showed that this kind of cylinder head cover is suitable for the automotive application.

Mesin pemindai tiga dimensi merupakan suatu alat pemindai titik-titik pada permukaan suatu obyek benda kerja. Keluaran dari alat pemindai ini adalah data titik (point cloud) yang merupakan suatu set data titik titik dalam sistem koordinat. Data-data titik ini digunakan untuk membuat model CAD 3 dimensi. Pemodelan 3 dimensi ini dapat digunakan dalam proses manufaktur, metrologi/inspeksi, visualisasi, animasi dan lain-lain. Makalah ini bertujuan untuk menyusun data-data titik yang didapatkan dari proses pemindaian produk cylinder head cover sehingga data yang diperoleh dapat disusun mirip perwujudan produk contoh yang dipindai. Tahapan yang dilakukan adalah pemindaian 3 dimensi, perbaikan, penyusunan berkas data, analisa simpangan, dan penyatuan berkas. Dengan tahapan-tahapan itu hasil yang didapatkan diharapkan memiliki deviasi rata-rata yang optimum. Hasil analisis deviasi dari data titik-titik (point clouds) menunjukkan bahwa pemindaian berkas pada bagian permukaan luar memiliki batas deviasi rata-rata yang lebih kecil (-0.1983 ~ 0.1912) bila dibandingkan dengan pemindaian berkas pada permukaan bagian dalam dari cylinder head cover (-0.6769 ~ 0.6319).
