Refuse Trucks are used to pick up garbage from houses. These trucks have huge robotic arms connected to the frame which are operated by hydraulic mechanism operated by the driver sitting inside the cab of the truck. The operator of the truck controls the robotic arm using a lever. Once the truck is positioned aside the garbage can, the operator moves the robotic arm outwards, grabs hold of the garbage can, picks up the garbage can and dumps the garbage into the truck. During this operation, the frame articulates and moves due to the frame suspension causing the cab to move along with the frame. This operation is performed about 1000 times a day, 5days a week for 12 years which could result in some amount of damage to the cab over its life. Since the time rate of application of the forces during the Automatic Side Loading operation is small compared to the lowest flexible mode of the cab, modal amplification is considered unlikely.

Abstract The aim of the paper is to describe how Volvo Construction Equipment uses a virtual product development process to analyze potential risks, find root causes and optimize future product development. A model based method is used to analyze a potential risk in the design of Wheel Loader transmissions. The risk was recognized from failure mode and effect analysis (FMEA), and a simulation model using AMESim modeling tool was developed to analyze the behavior of the new design. Together with test rig result, it is proved that the model based method gives a considerably accurate prediction of the system behavior. By using the model based approach, lead time for development process is reduced and important feedbacks from simulation model are obtained on early stage of the development. This paper further presents the use of the simulation model as a tool to predict the potential risks in the extreme operating conditions, which are difficult to test on the vehicle test bench.
AB Volvo and Deutz AG have signed a nonbinding memorandum of understanding (MOU) to explore the potential to extend their long-term cooperation with joint development of next-generation medium-duty engines for off-highway applications.
More powerful design tools, faster microprocessors, and software standards are a few of the tools that will help make possible a system-wide approach toward vehicle design.
The newest in Volvo's line of short-swing excavators, the ECR305CL is comparable in performance to standard-overhang configurations but can work in narrow confines and takes up just a single road lane for flexibility on the job.
Still a computer-based concept, the Fenix is a think-outside-the-box solution to the logistical and equipment difficulties that come with road paving. Using pods of asphalt mix and incorporating several features into one machine, the Fenix raises new ideas to solve an ongoing problem.
Heavy trucks that weigh less but still carry the same payload—that’s the future according to Volvo Group engineers. Though lightweight technology has mainly been the domain of Volvo Aero for its aircraft engine components, engineers at AB Volvo’s research company, Volvo Technology, believe using similar technology can reduce the weight of the cab and chassis in heavy trucks by at least 20% within 10 years.
Volvo CE is investing SEK 341 million in a new paint shop in the company’s articulated hauler plant in Braås, Sweden. This investment will lead to an increase in capacity in the plant, a reduced impact on the environment, and added improvement in quality.
The Volvo EC360CHR demolition machine, featuring an arm and claw able to tear buildings apart precisely, is able to reach further while keeping debris under control.
The first Volvo hybrid city bus pilot will start in the first half of 2016 in Navi Mumbai with Navi Mumbai Municipal Transport (NMMT). To promote environmentally friendly vehicles, the Indian government has recently launched the FAME India (Faster Adoption and Manufacturing of Hybrid and Electric vehicles in India) program, offering incentives on electric and hybrid vehicles.
A collaborative effort of AVL, Eberspächer, Topsoe Fuel Cell, Volvo, and Forschungszentrum Jülich, called the DESTA project, is exploring the benefits of utilizing solid-oxide fuel-cell APUs to help meet heavy-duty truck anti-idling requirements. In 2014, a vehicle demonstration on board a U.S.-market Volvo Class 8 truck will be performed.
