Project Review

Competition Objectives Mission Objective: Produce a vehicle for the Human Powered Vehicle Competition (HPVC) that a rider will mechanically power and control through their input force. Project Budget: $2,000

Competition Objectives Mission Objective: Produce a vehicle for the Human Powered Vehicle Competition (HPVC) that a rider will mechanically power and control through their input force. Project Budget: $2,000

Human Powered Vehicle

Functional Breakdown Targets/Metrics Top speed of 40 km/h Brake in 4 m at a speed of 25 km/h Turning radius of 6.0 m Supports 2670 N applied to top roll protection system (rps) in the event of a rollover Supports 1330 N applied to roll bar at shoulder height

Concept Generation

Concept Generation Concept #42 Concept #85 Concept #92 Figure 1: Concept 42 Figure 2: Concept #85 Figure 3: Concept #92 Concept #42 Concept #85 Concept #92 -Push/Pull lever actuate rim brakes -Hydraulic Steering -No fairing -Hand lever steering -Brake lever on handle actuate rim brakes -Nose, front, and rear wheel fairings -Hand lever steering -Brake lever on handle actuates disc brake -Full fairing with open sides

Concept Generation Concept #24 Concept #58 Concept #87 The next three most plausible concepts for comparison.. Concept #24 Disc brakes Partial Fairing Tie rod steering 3 point safety harness Concept #58 Direct tie rod steering Belt and CVT Car strap restraint Leaf spring suspension Disc Brakes Concept #87 Rack and pinion steering Steering column with wheel Partial fairing Hand lever brake actuation
