In view of increasing pressures of shortened development cycles and desire to save costs, inverse power law scaling has been devised for operative life estimation based on accelerated laboratory test data extrapolation. Derived from the Coffin-Manson's model of fatigue life, this analytical solution however is not capable in addressing probabilistic nature of fatigue. This paper is aimed to provide further insight into the operative life estimation of carbon steel stub axle using parametric models derived from integration of inverse power law stress-life model and probabilistic fatigue life distributions. Maximum likelihood estimation is applied in deriving the parameters of the parametric models and PSN curves are obtained from reliability function of accelerated laboratory test data. PSN curves at operative life as well as any life region can be estimated based on inverse power law acceleration factors. The procedures presented in this study can be applied in estimating the probabilistic fatigue life curves at an accelerated pace resulting in shortened development cycles.

SUBANG JAYA, 9 July 2015 – PROTON Holdings Bhd (‘PROTON’ or ‘the Company’) celebrates its 30th birthday today from when the first Saga model rolled out to the masses in 1985. In its bid to continuously promote the awareness on vehicle safety to its customers, PROTON starts its modest celebration with its customers by providing free 30 points safety inspection at all of its authorised service outlets nationwide. The programme will be ongoing until 31 October 2015 in all PROTON authorised service centres nationwide. The 30 points inspection include checks on fluid level, battery, wiper blades, radiator cap, pedal operation, suspension system, steering linkage and ball joint system, cooling system, fuel and brake system as well as tyre pressure (including spare tyres). Other than the free 30 points inspection, customers will also be given free consultation on engine and car maintenance, educate on how to differentiate genuine parts against imitation parts as well as enjoy discounts on parts and other promotions. As a kick-start to the free safety inspection, Dato' Abdul Harith Abdullah, CEO of PROTON was with the media at the launch ceremony which was done at a Petronas station in Damansara-NKVE. "We would like to thank our fellow Malaysians for the support they have given to us for the last 30 years. Therefore, this is a small token to our customers to get closer to them instead of just waiting for them to send their cars to our service centres. Our teams will be stationed at 5 different areas consisting of Petronas stations and an R&R area to cater to the needs of customers who are already on the way to their Kampung and holiday destinations," said Dato' Harith. “In previous years, PROTON has been offering between 18 to 20 points free inspections to our customers. However, in conjunction with the 30th anniversary celebration this year, we have increased the inspection to 30 points to give a more in-depth check on customers' cars. They include checks to the ABS module, alternator, transmission, power steering, fuel main pipe/pressure hose, radiator fan, starter, lamps, fusible link and accessories. This is partly our way of saying thank you to our customers,” Dato' Harith added. As part of the 30th Anniversary, PROTON is also offering various discounts on selected parts such as absorber, brake, clutch and timing belt. Elaborating further, he said that since PROTON was established, PROTON’s role has gone beyond designing and building vehicles. The Company provides value across the business value chain and drive the landscape of Malaysia's automotive industry. “PROTON’s 30 years journey is not just about making cars. It involved facilitating the development of an entire eco-system in the domestic automotive industry. This extends to the acquisition of technology; continued investments in research and development; training and retraining to develop highly-skilled and knowledgeable talent force; creating technically-superior supporting industries; and most importantly, promoting greater awareness and higher benchmark for vehicle safety to all consumers. As such, our responsibility for the next 30 years will remain, that is to produce globally competitive, good, safe & affordable cars for Malaysians,” Dato’ Harith added further. Apart from that, he said as a car maker, PROTON also has a social responsibility to educate and promote safety awareness to users, especially in supporting the government’s call to reduce road accidents during the festive seasons and school holidays. “The best way would be to reach out to our customers and help them be conscious on the condition of their cars as this can greatly reduce the number of accidents,” said Dato' Harith. Customers who take advantage of the free inspection will also bring home a goodie bag each. This programme, which is jointly organised with PETRONAS Dagangan Berhad (PDB) will be held on 9 to 15 July 2015, from 3 pm to 7 pm. Sharing the goal for road safety, PDB will also be distributing free PETRONAS Coffee Break pouches to motorists that drive into any of its 40 participating stations nationwide on 15 to 16 July, and 20 to 21 July 2015. The pouches, which contain tinned coffee and snacks, will be distributed from noon until stocks last. Further details can be found at www.mymesra.com.my. “PROTON takes seriously the safety and comfort of its customers. Through the services and offerings available in this campaign, we hope to contribute towards creating awareness to our customers and road users in the importance of vehicle maintenance & safety. The vehicles should also always be in good condition especially for use in long journeys. Hopefully, these efforts will help to reduce cases of road accidents which occur more frequently especially during the festive seasons,” said Dato’ Harith. Customers are advised to call in to our Customer Care Hotline 1800 888 398 or email to firstname.lastname@example.org for any enquiries and assistance.

SUBANG JAYA, 18 June 2015 – PROTON Holdings Berhad (PROTON) today launches the PROTON Design Competition 2015, which is into its second year. The theme for this year is "Design A Concept Car For The Malaysian Family". There are two categories, Category 1 - Secondary School, for those aged 13-17 years old and Category 2 - Individual, for those aged 18 years old and above. Secondary school students can send their entries in a group of 3 students and submission must be under their school name. For the individual category, anyone above the age of 18 years old can send their entries as an individual entry. The contest is only open to Malaysians holding a valid identity card and cash prizes of up to RM15,000 can be won. Other than cash prizes, 10 winners from both categories will also bring home a medal or trophy and certificate from PROTON. According to the Chief Executive Officer of PROTON, Dato’ Abdul Harith Abdullah, the Competition is one of the ways to nurture the spirit of creativity and innovation. “When we started the competition last year, we received such encouraging suggestions to allow a larger age group to show their talents in automotive design. So, instead of just opening up the competition to secondary school students and youths up to the age of 25, we have now open up Category 2 to anyone over the age of 18. We have talented Malaysians in the art of designing and we hope that we could further spur the interest in the industry especially with entries from aspiring car designers," said Dato' Harith. "This Competition will also give PROTON the opportunity to connect with the youth and allow Malaysians to get a first-hand experience in car designing. The process is a delicate one as it is not just about drawing a design but they would have to think of the overall concept as well in order to justify and sell to others the ideas behind that design," Dato' Harith added. All participants are required to design the exterior of the car according to the theme and submit the development sketches and renderings. If the participant has the advantage of using a design software, they can also submit a 3D digital visualisation of the exterior. Additional to this, participants for Category 2 must submit the interior vehicle packaging diagram for occupants and engine layout, and the illustrative renderings of the interior of the car. 3D digital visualisation of the interior is also welcomed. All sketches and renderings must be on A3 size paper and cannot be mounted, laminated or bound together. For the entry to qualify, participants must also provide a Design Brief in an A4 size paper containing not more than 350 words, the title of the design, the design concept and the unique selling proposition of the car. Participants can submit a maximum of three (3) designs and mail the entries to: PROTON DESIGN COMPETITION 2015 PROTON Holdings Berhad P.O BOX 07067 PEJABAT POS BESAR SHAH ALAM 40704 SHAH ALAM Entry closes on 1 September 2015 and participants are advised to read the Terms and Conditions thoroughly.
