The aim of this research is to create the center of mass testing machine for vehicles with maximum mass 3000 kilograms. By the performance of this machine is able to determine the center of mass 3 axis by horizontal longitudinal and vertical. On the other hand the verities of mass from 50 to 100 kilograms and the several of weight distribution at horizontal and longitudinal are applied to the condition of testing for reasonable to the position of the center of mass. The result of research discovered to the performance of center of mass tester was activated following to test conditions. Furthermore the weight distribution at longitudinal was the highest effect to the horizontal center of mass. By the way the value of weight distribution at horizontal is more effects to the longitudinal center of mass. Moreover increasing of mass was impact to the vertical center of mass and it’s independent to the position of weight distribution.

The aim of this research is to study the varieties of weight density distribution affect to the center of mass and vehicle stability. The weight density distribution tester was designed and changed the position of mass. Base on the center of mass is main points of vehicle stability. On the other hand FMCSA standard was applied to field test for considering of the brake performance and vehicle stability. The results of research discovered to the mass distribution on longitudinal plane are affected to the center of mass and absolutely influence at the right wheel on the front axle. In term of the braking performance it’s depends on the lateral mass distribution especially the center position of mass installed on longitudinal and horizontal plane and close up on the front axle (Y2). For the vehicle stability results the position (Y2) is the highest influence for yaw rate and sideslip. Otherwise the position (Y3) or the position of mass installed on longitudinal plane and nearly at the left wheel on the rear axle. Additionally wheel lock-up condition was appeared on the front axle only. Because the behavior of weight distribution on the front axle was decreased lead to mass distribution on longitudinal plane.

The aim of this research is to study the brake proportional affected to vehicle stability. Braking performance and vehicle stability testing are the main of research purposes. Otherwise learning research center and new researcher in automotive engineering are the minor research objectives. The results of research discovered to the braking performance depend on driver behavior. By the minimum deceleration was appeared on the non-proportion in front axle with braking ratio 0:100. In term of vehicle stabilities yaw and pitch moment are normally occur by the driving behavior. But the sideslip is an absolutely effect to vehicle handling. With the braking ratio 100:0 there is the highest risk for controlling a vehicle cause of the wheels were locked-up condition in the rear axle. Therefore the value of the sideslip was exceeded with the criteria. Furthermore these project researches were got the learning research center and the new researcher in automotive engineering field.

This research project aim is to discover information about the way constmcts the cogitative patterns of Business Management faculty in coherent of the business firms and for who interested in it. Our investigation by the generic questionnaire to survey the participants to probe the relationships among the data from the eager work forces of the students in Business Management faculty at Rajamangala University of Technology Phra Nakhon Dhurakijpundit University and persons they want to improve or to certify in higher certificate by surveyed the banks employees and the government services in totally 117 persons Both of qualification and survey researches were used. The researchers need as much information as possible for the complete testing tools with the 6 curriculums to construct the surveying form for 3 target groups. We used descriptive statistic to show the percentage data results. As described the percentage data from the participant data for evaluated and explained the behaviors of requirement to gain knowledge in the field of studies that they needs by usage the average and percentage of statistical analysis The studied result denotes the continuous studying fields of requirement on the curriculums at Business Management faculty by ordered popularization and higher requirement of 3 study-fields: Computer Information System Business English and Management. Mostly they want to take the periods of itudies during 1-12 months or the 1 year courses. Thus the short courses have to introduce for arrangement and preparation for them to get their certification and punctually respond to the consumers.
