Automobile side door glass squeaks and rattles during use. This abnormal noise can make the driver and occupants irritable and reduce the comfort of the automobile. This reduces the sales of this automobile. This paper analyzes and determines the cause of squeak and rattle during the lifting and lowering process of the side door glass of an automobile. The noise is due to four reasons. One is that the distance between the inner waterproof belt and the automobile side door glass of the automobile is unreasonable, causing excessive friction between the automobile side door glass and the inner waterproof belt during the automobile side door glass up and down movement. Other factors affecting squeak and rattle may be the distance between the automobile side door sheet metal and the automobile side door glass, the thickness of the automobile side door glass and the characteristics of the inner waterproof belt. The first two dimensions are analyzed using the 6 sigma method, and the structure of the inner waterproof belt is improved and the flocking position is adjusted. The squeak and rattle phenomenon is explained using the implicit dynamic analysis method ABAQUS, and the compression load deflection after the installation of the inner waterproof belt is 3–9 N/100 mm. This research completely solves the squeak and rattle problem caused by the up and down movement of the side door glass of the automobile. This research has significance for solving practical engineering problems.

Based on requirements of pipe transport systems on deepwater pipelaying vessel, a new pipe lifting mechanism was designed. It was composed of crank-rocker and rocker-slider mechanism with good lifting capacity and high efficiency. When the slider went to the upper limit position, the mechanism could approximatively dwell, meeting the requirement for transverse conveyor operation. According to the theory of dynamics, numerical analysis method was used to the dynamic analysis of the mechanism. The results showed the maximum counterforce was at the joint between the rocker and ground, and this calculation could be a guideline for the kinematic pair structure designing.

Abstract This paper presents an efficient extension of Rosenthal’s order-n algorithm for multibody systems containing closed loops. Closed topological loops are handled by cut joint technique. Violation of the kinematic constraint equations of cut joints is corrected by Baumgarte’s constraint violation stabilization method. A reliable approach for selecting the parameters used in the constraint stabilization method is proposed. Dynamic analysis of a slider crank mechanism is carried out to demonstrate efficiency of the proposed method.

Sektor perladangan kelapa sawit merupakan sektor yang sangat penting dalam industri pertanian dan merupakan penyumbang terpenting kepada ekonomi Malaysia. Namun begitu, isu tenaga buruh di sektor ini sering diperkatakan kerana masih berintensif buruh. Penyertaan golongan belia dalam sektor perladangan kelapa sawit adalah kurang memberangsangkan berbanding sektor lain walaupun sektor ini menawarkan peluang pekerjaan yang lebih luas. Oleh sebab itu, kajian ini bertujuan untuk mengenal pasti golongan belia yang lebih bersedia untuk melibatkan diri dalam sektor perladangan kelapa sawit berdasarkan faktor demografi mereka. Borang soal selidik digunakan bagi mengumpul data daripada responden yang terdiri daripada golongan belia berusia 18 hingga 35 tahun. Seramai 724 orang responden yang telah menjawab soal selidik ini mewakili setiap negeri di Malaysia. Data yang dikumpul dianalisis menggunakan kaedah analisis faktor dan model regresi logistik. Hasil kajian menunjukkan bahawa faktor jantina, bangsa, tempat tinggal, pengalaman, dan penglibatan ahli keluarga dalam sektor perladangan kelapa sawit merupakan faktor yang menyumbang kepada kesediaan belia untuk melibatkan diri dalam sektor tersebut. Faktor gaji, faedah, persekitaran kerja dan keselamatan perlu ditambah baik bagi menarik lagi minat golongan belia untuk melibatkan diri dalam industri pertanian negara khususnya di sektor perladangan kelapa sawit.   Abstract The oil palm plantation sector is a very important sector in the agricultural industry and is a major contributor to the Malaysian economy. However, the issue of labour in this sector is often addressed as it is labour-intensive. The participation of youths in the oil palm plantation sector is less favourable than the other sector although it offers greater employment opportunities. Therefore, this study aimed to identify youths who are better prepared to participate in the oil palm plantation sector based on their demographic factors. The questionnaire was used to collect data from respondents in the age range of 18 to 35 years. A total of 724 respondents answered this questionnaire representing each state in Malaysia. The data collected were analysed using the factor analysis method and logistic regression model. The results show that the gender, race, residence, experience and involvement of family members in the oil palm plantation sector are factors contributing to youths’ readiness to participate in the sector. Factors such as salary, benefits, work environment and safety factors need to be improved to attract more youths to participate in the agricultural industry, especially in the oil palm plantation sector. Keywords: Youth, labour force, oil palm, demographic factors, logistic regression.
