Abstract: This report outlines a load simulator design for MacDon Industries Ltd. for tractor performance testing. The load simulator is designed to receive hydraulic and mechanical loads induced by an external source and convert the loads into heat. This results in the external source experiencing a resistance, thereby simulating in-field harvesting action. The main objective of the load simulator design is to simulate a resistance of up to 60 horsepower. The main processes built into the load simulator design include: power input, heat generation and heat dissipation. The power input consists of multiple shaft and hydraulic couplers. This power is directed into a hydraulic pump, which transforms it into high pressure hydraulic flow. This is throttled by a valve, which decreases the pressure and increases the temperature of the flow. Thermal energy is dissipated from the flow using a radiator, to prevent overheating. Various concepts and components were considered during the development of this design. A concept that allows for quick and convenient switching between mechanical and hydraulic inputs was developed. The final dimensions of the design are 5.5 feet wide by 3 feet deep by 3 feet high. The load simulator is self-contained with a mass below 1000 kg, which allows it to be moved by a forklift. A heating element is implemented in the oil reservoir to allow testing in cold temperatures. The budget for this design project is $15 000. The estimated cost of the proposed design is $15 400.
