Dr. Grossi consults with clients on solving complex engineering problems involving consumer products, industrial machinery, process plant equipment, and a wide range of vehicles and components in the rail, automotive, and mining sectors. Drawing on his expertise in mechanical engineering, Dr. Grossi frequently directs and/or performs laboratory testing and advanced computer simulations. As an ISO-certified vibration analyst, Dr. Grossi is qualified to establish, direct, and perform programs for condition monitoring and diagnostics of machines, process plant equipment, and industrial systems.

Consumer Products

Dr. Grossi conducts engineering investigations of consumer products and has presented his findings to the U.S. Consumer Product Safety Commission (CPSC). His consumer product work includes targeted testing and analysis of products, product performance evaluation, failure analysis, and engineering analyses in the context of product safety, compliance, and recall investigations. Specifically, Dr. Grossi has investigated a wide range of consumer products including, but not limited to, kitchen appliances (e.g. pressure cookers, blenders, coffee makers, ice cream machines, drinkware, can openers, ice makers, electric ranges), home appliances (e.g. washers, dryers, water heaters), indoor and outdoor furniture (e.g. beds, office mats, chairs, chaise lounges), lighting fixtures, toys, strollers, garden hoses, exercise equipment, robotic pool cleaners, air compressors, e-bikes, e-scooters, and bicycles.

Industrial Machinery and Process Plant Equipment

Dr. Grossi performs investigations involving failure analysis, risk assessment, and safeguarding of industrial machines, often in the context of worker injuries or fatalities. Dr. Grossi is also experienced in investigating the failure of process plant equipment such as pipes, piping components, pressure vessels, flexible hoses, and auxiliary equipment, such as pumps, compressors, valves, and couplers. Some of the machines and products he has investigated include press brakes, lathes, milling machines, pressure vessel explosions, boom lifts, forklifts, various CNC machine tools, construction tools, escalators, elevators, and automatic doors.

Railroad

Dr. Grossi conducts failure analysis, performance evaluations, and mechanical integrity assessments of railcar structures in both freight and passenger service. His investigations have included, for example, derailments, engineering analysis of truck (bogie) components, railcar rollover events, railcars transporting hazardous materials, and hopper cars with corroded structure. Dr. Grossi also performs stress calculations using finite element analysis (FEA) and evaluates derailments, vehicle stability, and vehicle dynamics using various analysis tools, such as multibody dynamics (MBD) simulations.

Automotive

Dr. Grossi performs mechanical analyses of trucks, trailers, passenger cars, and vehicle components, including failure analysis, performance evaluations, compliance reviews, and durability testing. Some of the vehicle systems he has investigated include specific aspects of pneumatic tank trailers, flatbed trailers, hydraulic mechanisms, internal combustion engines, electric motors, tires, wheels, brake hoses, fuel pumps, timing chain systems, and alternators. During his employment at Gamma Technologies, Dr. Grossi has analyzed the mechanical performance of several engine architectures, with major focus on vibration and bearing analysis.

Mining

Dr. Grossi performs engineering evaluations related to the mechanical performance of heavy machinery including excavators, haul trucks, wheel loaders, and surface miners. Dr. Grossi worked at Caterpillar, where he performed design evaluation and multibody dynamics analysis of a wide range of heavy machines. Dr. Grossi is Mining Safety and Health Administration (MSHA) Part 46 trained.

Dr. Grossi's academic expertise includes dynamics and vibration, multibody dynamics analysis of rigid and flexible bodies, and nonlinear finite element analysis. His doctoral research focused on the advanced computer modeling of specific aspects of rail vehicles, railcar tanks, liquid storage tanks, trucks, and tires. Dr. Grossi often serves as instructor at the Vibration Institute, a U.S. institution accredited by the ANSI National Accreditation Board, where he teaches courses on vibration analysis of machines to industry professionals.
